3.3 MAIN COMPONENTS AND OPTIONS
MAIN COMPONENT ALTERNATIVE
COMPONENT
Feeder
The feeder ensures even and continuous material flow into the crusher. The feed material smaller than the opening of the feeder grizzly goes through the grizzlies passing the crusher. This increases the capacity and prevents material packing in the crusher.
TK11-42-2V
Crusher
The Nordberg C jaw is the heart of the Lokotrack. The crusher crushes the feed material into smaller pieces.
C110
Tracks
The Lokotrack moves with the tracks. The tracks ensure the movement of the machine.
D57-LONG
Engine
The operating power of the Lokotrack is generated from the Caterpillar diesel engine. The engine runs the hydraulic pumps.
C13
Main conveyor
The main conveyor transfers the crushed material from the crusher to the stock pile or to the next process.
3.4 ADDITIONAL EQUIPMENT
• Side conveyor
The optional side conveyor transfers the material that has passed the feeder grizzlies to the stock pile beside the machine.
• Magnetic separator
The optional magnetic separator is installed above the main conveyor. It separates magnetic objects from the crushed material and transfers those to a separate pile beside the machine.
• Screen module
The screen unit is connected to the unit’s frame structure with locking pins. The screen module requires own hydraulic connections and it is driven by the unit’s hydraulics and controlled by the Lokotrack IC system.
• Dust protection by high pressure water injection
The high pressure water pump is installed into the unit's hydraulic PTO and located under the hydraulic cabin.
• Hydraulic outlet
The hydraulic PTO (Power Take Off) connectors are installed to the bottom of the hydraulic cabinet. The outlet has quick couplings.
• Engine preheater
In cold climates the engine pre-heater
(WEBASTO) can be engaged to heat the engine block and coolant water.
• Radio control for feeder and track drive The radio controller can be mainly used for driving the unit and adjust the feeding device.
• High voltage generator (400/460VAC) The generator is installed to the end of the hydraulic cabinet and its driven by the hydraulic PTO.
• Feed hopper extensions
The extension wings, which can be installed into the side walls increase the feed hopper size from 6m3 to 9m3.
• Automatic lubrication of the C-jaw crusher bearings
The centralized and automated lubrication device greases the crusher bearings according to the set intervals.
• Breaker for C-jaw crushers
The impact breaker can be installed to break oversize material in cavity.
• Fuel filling pump
The fuel filling pump is electrically (24VDC) driven and can be controlled from separate control switch in the hydraulic cabin’s electrical box. The fuel filling pump has a protection for the
overfilling.
• Intake air pre-cleaner
This system is recommended for extremely dusty conditions.
Pre-cleaning takes place in the special tubes. In the tubes the dust particles are separated from the intake air. Pre-cleaned air goes to primary filter and the dust goes through the scavenge hose to the exhaust ejector and is ejected with the engine exhaust.
3.5 HYDRAULICS AND ELECTRIFICATION
The main hydraulic power is produced by
variable-displacement axial piston pumps installed directly into the engine.
Hydraulic operations are controlled electronically by IC-system or/and by manual valves. The IC-system controls the engine revs, which create the power to the pumps. The hydraulic pressure created by the pumps is then delivered through hydraulic valves to the drive device in question. The hydraulic circuit also includes a
thermostat-controlled cooler, a hydraulic main suction valve, a pressure filter and a return filter.
The 24-VDC electrical system is used for the functions of the engine and the IC-system to control the hydraulic valves, for working lighting and for the functions of the possible accessories.
The optional high voltage electrical system is used for the functions of possible accessories. The electric power is generated by the generator connected to the hydraulic system.
3.6 CONTROLS
• The control center (1) is located on the right side of the LT.
• The hydraulic center (2) (on the left side of the machine) has controls to the main functions of the hydraulic system.
• A portable drive control box equipped with a 6-meter connection cable functions as a drive controlling device. A radio control is available as an option. The cable connection plug (3) is located below the control center and under the feeder. The drive control box is stored in the
equipment cabin next to the main control center (5).
• Under the feeder in the rear beam, there is a hydraulic valve set (6) for controlling the side walls of the feedhopper.
• The control panel (7) on the working platform next to the crusher can be used to control the feeder and to crusher operations.
A more detailed description of the controls is in chapter 4 “Component locations”.

Figure 5.19 Crushing postion
IMPORTANT!
Observe great care when driving the unit onto the low bed due to the reduced ground clearance at the conveyor end.
IMPORTANT!
The LT must be on an even ground, before the discharge conveyor can be folded.
8. Check that there is no uncrushed material left in the crusher.
9. Make sure that the whole length of the tracks is consistently on the ground in order to avoid excess vibration and swinging. 10. Check the spirit levels in the inner walls of
equipment cabin to ensure that the LT is in the horizontal position.
NOTE: If the unit is equipped with a screen
module, lower the screen module support legs down. Refer to screen module instruction manual.
Figure 5.20 Make sure that the crushing site is steady enough.
Figure 5.21 The spirit levels in equipment cabin
WARNING!
Hydraulic support legs may be lowered automatically when the process is started.
Risk for severe injury if person gets under the moving support legs. To prevent this, lower the support legs manually close to the ground before starting the process.
5.4.6 By-pass chute
Location of the by-pass chute hatch.
The material flow that passes below the feeder grizzlies can be directed towards the main conveyor (fig. 5.22) or towards the optional side conveyor (fig. 5.23). With the optional screen deck, materials larger than the mesh openings can be directed towards the main conveyor (fig. 5.24). Turn the lever to change the direction of the material flow. When using the centre position, lock the lever in place using a bolt.
Figure 5.22 The chute has been directed towards the main conveyor.
Figure 5.23 The chute has been directed towards the side conveyor.
Figure 5.24 The flow of materials has been screened and directed either to the side conveyor (pass-through) or to the main
conveyor.
WARNING!
Make sure that the machine is stopped (feeder, crusher, conveyors and engine) before entering to chute. Ensure that it can not be started during cleaning operation.
5.4.7 Crusher speed selection
The IC system of the Lokotrack controls the crusher speed. The crusher can run either on target speed or with a stabile fixed speed.
5.4.7.1 Target speed
When the target speed is set on the IC system, the crusher tries to maintain the desired speed value by adjusting the control current to the crusher pump. Refer to the IC system manual for more details.
5.4.7.2 Stabile fixed speed
When the target speed function is disabled the fixed control current can be used to drive the crusher. With this way of control, the IC system keeps the control current stabile all the time. Therefore it does not effect to the increasing and decreasing loads, which alter the speed of the crusher.
5.4.8 Feed control
The feeder can be stopped and restarted again during the crushing process. The “feeder start” and “stop” buttons are located in the remote control box on the service platform. If the machine is equipped with a radio control feature (optional), the feeder can be started and stopped using the radio control feature.
To stop and restart the feeder do the following: 1. Stop the feeder during the crushing process
by pressing the "feeder stop" button. 2. Restart the feeder after it has stopped
completely by pressing the "feeder start" button.
NOTE: The feeder starts automatically when the
process is started and stops when the process is stopped. If the hydraulic temperature of the unit is extremely cold (-5oC/23oF), the system will ask to carry out a cold start of the process. The feeder will not start until the temperature of the oil has reached a certain temperature.
When the process is running and the feeder is in automatic mode, the IC controller adjusts the feeder speed according to the crusher and other device operations in the LT. The IC controller tries to keep the best and equal material flow to the crusher to prevent overfilling.
In order to stabilise the feed rate, the feeder always starts at minimum speed regardless of the speed setting. After a while the speed changes to the set value.
In order to control the capacity, the feeder speed can be adjusted using the feeder speed +/- switch, but only in feeder manual mode. The switch is located in the control box on the service platform. The speed can also be adjusted by using the optional radio controller.
NOTE: When the process is running, the
automatic control controls the stopping of the feeder. The feeder will stop if the speed of the crusher decreases or the level indicator (optional) of the crusher indicates an alarm.
NOTE: If the feeder speed is too high, stones may
fall over the flanks of the hopper.
NOTE: Radio control will by-pass the feeder
controls located in the remote control box on the service platform.
The best capacity can be reached by having the feeder remain running for as long as possible. An overfilled feeder will reduce the capacity and cause unnecessary wear.
5.4.8.1 Feeder Automatic Control
The feeder control mode can be either manual or automatic. The selection is done in the feeder parameter F5. Refer to the IC Instruction Manual for the parameter change.
If manual speed is selected, feeder speed is controlled by a remote control housing or radio control. If the crusher operation pressure or speed exceeds the preset alarm values, feeder speed will automatically be reduced in prior to stop. It is recommended to use manual speed when the unit is followed with a secondary stage crushing or a screen. Feed rate does not fluctuate as much as with automatic feeder speed.
It is recommended to use automatic feeder speed when material throughput fluctuation does not interfere the following process, eg. recycling. With automatic feeder speed the throughput of the crusher can be maximized.
5.4.8.2 Feed Material
Refer to the C-Jaw instruction manual for the feed material.
5.4.9 Crusher setting
The crusher setting is the most important crusher parameter since it determines the crusher's capacity as well as the top size of the crusher product. It is therefore indispensable for everyone to understand how the crusher setting is measured.
Refer to the C-Jaw instruction manual for setting measurement
5.4.10 Clearing of the jammed main conveyor
NOTE: Never try to clear the blockage with
excavator.
If the conveyor stops, follow these instructions: – Stop the process immediately.
– Clear the jammed main conveyor as well as possible. When most of the material is removed, the main conveyor can be started by using a manual lever in the hydraulic valve manifold.
NOTE: Do NOT use this method if the rock is too
big to pass under the magnetic separator!
5.4.11 Removal of the steel
Always stop the machine (feeder, crusher,
conveyors and engine) before removing metal from it. Make sure that the machine can not be started when removing metal from it.
WARNING!
Risk of falling if the crusher setting is measured from above the crusher. Use safety harnesses!
5.4.12 Crushing site
The unit should be located near the material pile to make loading easy and quick. Shape the feed material pile with a wheel loader or excavator so that it is distributed over a small area and piled high enough for easy loading (fig. 5.25).
Figure 5.25 First shape the material pile The location of the discharge pile must be chosen so that it doesn't cause any danger to workers or passers-by. Make sure that there is enough space for the discharge pile, the discharge machinery (wheel loader or excavator) and the lorry
(fig. 5.26).
Figure 5.26 General measures taken on the site.
The place where the crusher is to be located must be even. The machine must not be allowed to sway. The surface below the crusher must be levelled and evened out. Spread some fine-grained material on the ground, distributing it evenly (fig. 5.27). Next, harden the underlying ground by driving the unit back and forth over the site (fig. 5.28).
Figure 5.27 Spread some fine-grained material on the ground and even it out.
Figure 5.28 Strengthen the underlying ground by driving the unit back and forth over it.
During the crushing process, make sure that the unit is in horizontal position. The maximum inclination allowance is 1 degree in lateral direction and 2 degrees in longitudinal direction
(fig. 5.29 and fig. 5.30).
Figure 5.29 The maximum lateral inclination permitted during the crushing process is 1
degree.
Figure 5.30 The maximum longitudinal inclination permitted during the crushing
5.4.13 Feeding measures 5.4.13.1 Loading Equipment
The unit can be loaded with the help of either an excavator or a wheel loader.
• LOADING USING AN EXCAVATOR The unit can be loaded from the side or the rear. Find a suitable loading site and move the excavator bucket to its loading position. Then drive the unit into a suitable position below the excavator bucket. The operator of the excavator must have full visibility to the upper part of the feeder (fig. 5.31).
Figure 5.31 The operator of the excavator must have full visibility to the upper part of the feeder. Load the material into the back wall of the feeder, on top of the solid base (fig. 5.32).
Figure 5.32 Load the material into the rear of the feeder, on top of the solid base.
If the feed material contains metals, someone should stand next to the feeder and remove the metal pieces before they are able to enter the crusher.
• LOADING USING A WHEEL LOADER The unit can only be loaded from the rear. The maximum bucket width is 2400 mm (95") for standard-size hoppers. In the case of 6 m3 hoppers, the maximum bucket width is 3200 mm (126"). If required, use the feed material to make a loading ramp to ease access to the feeder.
Drive the unit as close to the pile as possible to make loading quick and easy.
NOTE: The feeder has two basic applications:
a. stabilising the feed rate
b. separating the fine material before it enters the jaw crusher.
If the feeder is too full, it will not separate the fine material, which in turn will result in decreased operating capacity.
NOTE: Do not drive the excavator bucket into the
material or try to force the material into the jaw cavity.
5.4.14 Recycling
In recycling applications the metal objects should be removed from the feed before entering the crusher.
Maximum alloved diameter of the steel Ø16 mm. Maximum allowed length of the steel in the feed 1,0 m.
The most efficient way is to prepare the feed material and remove all the metal from it before loading it to the LT110C.
The optional magnetic separator can be used for the removal of small metal objects.
5.5 STARTING THE CRUSHING PROCESS
1. After a cold start, let the engine idle for a few minutes or until it has warmed up. 2. Make sure that there is nobody on top of or
near the LT. Warn everyone in the vicinity. 3. Start the process with the button (2) on the
control panel. Monitor the messages appearing on the display screen of the process control system (4).
4. When the equipment has started up, proceed with the crushing.
The crushing parameters are adjusted via the process control system. Further instructions are provided in the separate instruction manual for IC-system.
5.6 DURING RUNNING
When the LT is running, observe the normal function of the machine parts. If abnormalities occur (loud noises, strong odors, components that heat up intensively, etc.), the equipment must be shut down and the cause determined immediately. Any error messages concerning the operation of the machine will appear on the process control system screen. If the machine gives an alarm or shuts down, check the messages on the display screen first.
Figure 5.34 Starting from the control center
WARNING!
Shut down the crusher before climbing on top of the machine. Blockages, etc. must be cleared with the engine shut down.

5.7 MOVING ON THE CRUSHING SITE
1. Stop feeding the material and let the fed material pass through the crusher and the conveyors.
2. Stop the process by pressing the button (3) on the control panel.
3. Wait for the crusher and the conveyors to stop (If the unit is equipped with a screen module, lift the module support legs up before moving. Refer to screen module instruction manual).
4. Drive the equipment as instructed in section 6.2.
5.8 STOPPING THE CRUSHING
Stop the crushing process by pressing the button (3) on the control panel.
5.9 SHUTTING DOWN THE ENGINE
Let the engine idle without load for a few minutes before shut-down to allow the temperature to settle. It helps avoid ‘after-boiling’ of the coolant and cool the supercharger, which extends the operating life of the engine and reduces operating failures. Shut down the engine by turning the key switch (1) to the “0” position.
Figure 5.35 Shut-down from the control center.
WARNING!
The crusher may rotate for several minutes after the crushing process has been stopped.
IMPORTANT!
Do not shut down the engine before the crusher has stopped completely.
WARNING!
After the engine has been shut down, some pressure remains in the hydraulic system and in the cooling system of the engine. Let the machine cool down sufficiently before opening the pressurized components, and always make sure that the system is pressure-free before performing any servicing or checks.
