with suspension hook for stationary use.

Illustration 2

4.3 Functions

The load is lifted, lowered or tensioned by operating the lever. The load pressure brake prevents automatic

lowering of the load.

NOTICE!

If used "overhead" or "lashing" undefined forces may appear. We recommend to use a hoist with

slipping clutch for these cases.

NOTICE!

The best protection against functional failures in case of extreme environmental impact is the regular use of

the equipment.

4.4 Important components

Gearbox

Gear box parts are made of high-quality material.

Load pressure brake

Holds the load in any position.

Housing

Made of steel plate.

Load chain

According to EN 818-7-T high quality chain. All components match precisely to each other. Use only original

chains.

Please read chapter "Safety".

Before loading the hoist make sure the hooks are placed safely. The safety catch of the hook must be

closed.

Make sure that the fastening position cannot be changed either by the load nor by other influences.

7 Operation

Only people that are familiar with the operation of the lifting devices and cranes may be entrusted with their

operation. They must be authorized by the employer for the operation of the equipment. The employer must

ensure that the operating instructions are available near the equipment and that they are accessible for the

operating personnel.

7.1 Devices from 750 kg up to 6000 kg

Before start up please make sure the free-wheeling mechanism is deactivated.

Forcible pulling may possibly close the brake and stop the chain. Should this be the case place the switching

pin in position "▼", do some lowering operation movements and begin lifting again.

Lifting or pulling

Turn the switching pin in position lifting (1) or

pulling (2) as marked on the type plate and move

the load by operating the hand lever.

Lowering or relieving

Turn the switching pin in position lowering or

relieving (2) and move the load

by operating the

7.2 Brake and pawl

The brake system needs a minimum load of 3% of the capacity.

Only this minimum load makes sure that the load-pressure-brake closes correctly. When the brake closes

correctly, the load is safely held.

DANGER!

Working situations with no guarantee that the minimum load is charged, are forbidden!

The brake remains closed (stuck) if:

The ratchet lever hoist is uncharged without lowering the load, i.e. in case of vertical lifting/lowering or in

case of horizontal pulling/tensioning.

The load hook is pulled against the housing and got stuck there.

The chain does not move, the load cannot be lowered.

Remedy:

Charge the ratchet lever hoist again

Release the brake by setting down the load.

OR: Turn the switching pin to position "Lowering" and release the hand lever with a strong jerk in direction

"▼".
