(1) Move the crane to the firm ground. Fully retract the suspension lock cylinders to lock the suspension. (2) Set the PTO switch to the "ON" position.
The ACS will begin its self-diagnostic process at that point. (3) Outrigger setting
1) Use the outriggers to set the crane in a level position. As a rule, fully extend all outriggers as far as possible when leveling the crane and inset the stopper pins in each outrigger to check the extension width.
2) Check that all tires are lifted off the ground.
(4) ACS setting
1) Set the outrigger setting status that corresponds to the outrigger extension width on the working status setting screen.
2) Set the boom status that corresponds to the boom operation status on the working status setting screen. 3) Press the ACS display switch to complete the ACS setting.
(5) Perform the ACS preoperational check procedure.
Be sure to perform the ACS preoperational checks before starting crane operations. 1) Press the function switch to display the ACS preoperational
check screen. Check that the ACS is working correctly.
possible danger in an emergency of the ACS system. Therefore, give the key to the safety supervisor when on the work site.
The ACS emergency switch is only used to take emergency action to avoid a serious accident. Before crane operation, take the key off the switch and it must be kept by the safety supervisor. If the ACS emergency switch is set to the"release" position intentionally when operating the crane, the crane tipping over or other serious accident can be caused.
(541A-0157-0E) (7) Lever position
Sit in the operator's seat and lock the console lock lever to set it to the working position.
(8) Set the crane operation switch to the "ON" position.
The crane is automatically stopped when the left console is tilted (raised), so there will be no response to movement of the crane control levers, prdals etc.
graph, the sound alarms, and voice alarms. In particular, it is necessary to be especially cautious during slewing operations. Slewing is not stopped automatically.
(2) If the ACS automatically stops the crane motion, immediately take measures to avoid the danger, such as by raising the boom, retracting the boom, lowering the load, or reversing the slewing direction.
(3) If an error code is shown on the ACS auxiliary display, perform an inspection of the problem and contact your authorised KATO dealer if the error cannot be resolved.
: Set the crane operation switch to the "ON" position and push the right control lever left to derrick the boom. : Set the crane operation switch to the "ON" position and push the right control lever right to lower the boom.
When the boom is long or the jib fitted, the crane will tip over if the boom is lowered below the critical angle even if there is no suspended load. Refer to Service data to find the critical angle.
(4210-0039-1E)
Precautions on derricking and lowering the boom ・ Work the lever gently.
Sudden lever operation causes strong shocks in the structure of the crane, particularly when a load is suspended, so work with care.
・ The working radius increases as the boom lowers, possibly causing an overload which could tip the crane, so proceed with caution.
・ Never try to drag a load sideway or toward the crane by derricking the boom. ・ Rapid, careless derricking and lowering of the
boom causes the hook to swing and strike the underside of the boom, making dents and deformation which harm the boom. Be particularly careful when the boom angle is large and when the hook is close to the boom top.
: Set the crane operation switch and main or auxiliary winch switch to the "ON" positions and pull the right or left control lever backward to wind up the winch.
: Set the crane operation switch and main or auxiliary winch switch to the "ON" positions and push the right or left control lever forward to lower the winch.
(1) Set the crane operation switch to the "ON" position.
(2) When operating the main winch, set the main winch switch to the "ON" position.
(3) When operating the auxiliary winch, set the auxiliary winch switch to the "ON" position. (4) Use each winch lever to hoist or lower.
When you return each winch lever to neutral, the automatic brake device automatically applies the brake. (5) Drum rotation detector switch
The rotation of the winch drum which is selected by this switch is detected during winch operation and a buzzer will sound to
indicate that the winch drum is rotating. NOTE
The buzzer sound is the same for hoisting and lowering. NOTE
The buzzer sound becomes faster the faster the drum rotates. When the drum speeds up f urther, the buzzer sounds continuously and then dies away.
Precautions on hoisting and lowering
・ Never drag a load sideways, pull it towards the crane or operate the lever violently as they are extremely dangerous to cause a serious accident.
・ Never continue lowering after the hook has reached the ground as this can cause the wire rope to tangle on the drum.
(4210-3250-0E)
・ Where it is absolutely necessary to use "joint hoisting" between the main hook and the auxiliary hook with the jib mounted, set the "boom operation status" to "jib operation" on the ACS "working status setting screen" and work at less than the rated lifting capacity of the jib.
・ Further observe the safety regulations and laws of the country where the crane is used.
(611A-0042-0E) NOTE
Using the flow control system, you can hoist or lower the load at a constant speed regardless of the weight of the load.
Use the boom extension/retraction switch to select the boom extending or retracting sections.
Extend : Set the crane operation switch to the "ON" position and depress the boom extension/retraction pedal forward to extend the boom.
Retract : Set the crane operation switch to the "ON" position and depress the boom extension/retraction pedal backward to retract the boom.
