1. Preface
Our high quality winch systems, are based upon our unique hydraulic piston motors, developed through a wealth of experience accumulated over 30 years in marine and industrial areas. Today this ongoing development work has resulted in the powerful COMPACT winch. New, as well as established technical solutions, contribute to the creation of this product. The most desirable features and operating reliability have been designed in this winch.
This instruction provides necessary information for installation of the winch. In order to find particular information, just search for the wanted section as listed in the table of contents. However, changes in the equipment may occur. We therefore reserve the right to introduce amendments in the manual as we deem necessary without notice or obligations.
2.2 Application area
All new and rebuild applications, should always be ap-proved and supervised by MacGREGOR personel.
2.3 Mounting
Carefully follow the instructions and be aware of the high weights and forces during lifting.
2.4 Before starting up
Before starting up new, rebuild or just worked on appli-cations, all accessories and safety arrangements func-tions, should be controlled/tested.
2.5 Periodic maintenance
Notice the intervals in Maintenance chart, section 5, and keep a record.
2.6 Dismounting
Carefully follow the instructions and be aware of the high weights and forces during lifting.
2. Safety precautions
It is of high importence that the safety precautions are always followed, if you are unsure about something, please don´t hesitate to contact your nearest MacGREGOR-office for advice.
2.1 Warning signs
In this instruction you will find the following signs which indicate a potential hazard, which can or will cause personal enjury or substantial property damage. De-pending on the probability of the hazard, and how seri-ous the injury or property damage could be, there are three levels of classification.
DANGER!
Is used to indicate the presence of a hazard which will cause severe personal injury, death, or substantial property damage if the warning is ignored.
WARNING!
Is used to indicate the presence of a hazard which can cause severe personal injury, death, or substantial property damage if the warning is ignored.
CAUTION!
Is used to indicate the presence of a hazard which will or can cause minor personal injury or property damage if the warning is ignored.

3. The COMPACT winch
This COMPACT winch instruction is including the COMPACT motor and the MDA brake. The COMPACT motor has also a seperate instruction, section 6.1.
The MDA brake has also a seperate instruction, section 6.2.
The COMPACT winches features both hoisting and luffing winches. The drums are guided at the bearings

inside motors and brakes.The pulling force is transmitted by spline shafts in the centre of the drums, to the motors, brakes and brackets.
The hoisting winch (Fig. 2) stand on feet bolted to the floor, and the luffing winch (Fig. 1) hang in brackets on the wall.

5.2 MDA 14 & 21
- Grease the spline on the driven shaft with Texaco Multifac EP2 or equivalent.
- Align the brake with the driven shaft (Fig. 6).
- Push on the brake by hand.
- Open the brake with hydraulic pressure, 20 bar, turn and align with the M20-holes.
- MDA 14 & 21 are mounted with M20x70 (strength class 10.9). Tightening torque 540 Nm.
5. Mounting the Brake onto the Winch
5.1 General
The brake is of the fail safe multi disc type. During normal operation hydraulic pressure keeps the discs within the brake separated, allowing shaft rotation. If hydraulic pressure is lost, springs force the discs together, stopping rotation of the winch drum.

Fig. 7. Brake MDA 42.
5.3 MDA 42
- Align the brake with the driven shaft (Fig. 7).
- Push on the brake by hand.
- Open the brake with hydraulic pressure, 20 bar, turn and align with the M20-holes.
- MDA 42 are mounted with M20x70 (strength class 10.9). Tightening torque 540 Nm.
- Fill up the brake with hydraulic oil, 1 litre.
Note:
Be careful not to damage the pin in the centre of the brake!
