JACKS WITH LOCKING COLLARS (TYPE SR)

All models can be supplied with threaded pistons and locking collars to

mechanically support the load without relying on the hydraulic circuit.

When the load is at the required position, rotate the locking collar clockwise

until it rest hand-tight on the top of the jack body.

To undo – operate the jack so that the hydraulic circuit just takes the load of

the locking collar. Rotate the collar anticlockwise until it reaches the top of the

piston.

JACKS WITH LIFTING CLAWS (TYPE C)

Claws are supplied as an accessory to provide a low height lifting point. When

fitted, lifting must always and only be carried out on the toe of the claw. See

Figure 2.

The capacity of the claw is 40% of the capacity of the jack to which it is fitted.

Lifting claws must NOT be fitted to threaded piston jacks. Lifting claws must

only be used with jacks having extended bases that extend under the toe of

the claw. They must ONLY be used for vertical movements of loads.

The recess on the underside of the top of the claw fits around the top of the

piston. The heel of the claw rests against the front face of the jack. Ensure

that the claw is seated properly before use and that the toe is as far under the

load as possible.
