3. INSTALLATION
Before installing the HH250150P hoist make the following checks:
1. Check that the hoist is in good condition.
2. Check that the correct hoist capacity is to be used.
3. Check that the hooks and safety latches are in good condition.
4. Check that the low limit stop is in place.
5. Check that the load chain is correctly fitted.
6. Check that the anchor point is sufficient to take the intended load.
After successfully completing the preliminary checks, install the HH250150P hoist on its anchoring point and
perform the following checks:
1. Check that the HH250150P hoist is properly suspended by its suspension hook (item 5, fig. 1) and that the
hook safety catch (item 6, fig. 1) is properly closed (see figs 2 and 3).
2. Check that the load chain has not become twisted during installation.
3. Without load, check that the up and down functions operate correctly.
4. When using the hoist with a push suspension trolley, without load, check that the trolley moves freely. If
using a geared suspension trolley, without load, check the direction of movement by pulling on the trolley
hand chain. The movement should be carried out on a strictly horizontal plane.
After successfully completing these checks, place the load in position and ensure:
1. The anchoring accessory of the load sits fully in the hook and does not prevent the catch from closing
correctly (see figs. 2 and 3).
2. The load on the hoist is free to align itself with the machine’s anchoring point.
4. OPERATION
4.1 OPERATING PRINCIPLE
The HH250150P hoist is operated by means of an actuating handle (item 7, fig. 1) which is moved back and
forth by the operator to lift or lower a load, pull a load, or apply tensioning.
4.2 INSTALLING THE LIFTING HOOK ON THE LOAD RIGGING POINT
If installation of the lifting hook requires adjustment of the chain length, proceed as follows:
1. Make sure that there is no load on the chain.
2. Set the movement selector lever (item 8, fig. 1) to the neutral position “0”.
3. With no load on the machine, turn the load wheel (item 9, fig. 1) anti-clockwise to open the brake; the
chain is released.
4. If it is not possible to turn the load wheel put the selector lever in the down position and operate the
lever handle wrilst exerting some force on the hook side of the chain with your hand. Place the selector
lever in the “neutral” position and pull on the chain, which is thus released, using the low limit stop.
5. Secure the lifting hook to the load (or to a fixed point), or to the point where tension will be applied.
Apply a slight tension to the chain by pulling on the chain using the low limit stop.
6. Turn the load wheel clockwise; the brake is closed. The chain is engaged in the hoist.
