3. MOUNTING

3.1.

Unpack the hoist and check contents against the items listed below. Should

there be any damaged or missing parts contact your supplier immediately.

Contents

1. Hoist assembly.

2. Double line pulley and hook (loosely assembled).

3. Four each of: bolts, spring washers and washers.

4. Two mounting brackets.

3.2.

Ensure that the selected hoist support is sufficiently strong and will also hold

the hoist in a horizontal position. If alternative mounting brackets are

fabricated, ensure that these are at least as strong as those provided, and

align with the mounting holes (fig.1.A) in the hoist.

4. OPERATION

fig.1

WARNING! Before using the hoist ensure that you have read, understood

and apply the safety instructions in Section 1.

IMPORTANT: In an emergency press the emergency stop button to halt the

hoist (fig.2.7), to release the emergency stop button, turn it clockwise.

4.1. Ensure that the load to be lifted is directly below the hoist and that any lifting

straps, ropes or chains being used are capable of supporting the weight.

4.2.

With mains power switched on, operate control switch (fig.2.1) to bring hook to

load height. Press lower half of switch to lower hook and upper half to raise

hook. Release switch to stop hoist.

4.3.

Attach hoist hook (fig.2.2) to load, ensuring that safety bar (fig.2.3) is fully

closed.

4.4.

Use control switch (fig.2.1) to raise or lower the load to the required height.

4.5.

To carry out a double line lift, first hook the single line hook in aperture in hoist

frame (fig.3.1). Then take double line pulley and hook (fig.3.2), remove 'R' pin,

shaft and washers and undo nyloc nuts and remove small bolts (fig.3.3).

Place pulley on cable loop between hoist drum and single line hook. Replace

hook and refit shaft, washers and 'R' pin, then refit small bolts and tighten the

nyloc nuts on them. Ensure that pulley is free to rotate. Proceed as above in

4.1. to 4.4.

Notes: 1. It is important not to completely empty the cable drum, it is designed so

that if the cable is run out to it's end, the cable will engage with the safety

bar (fig.2.6) and cut the motor out, and there will still be sufficient

windings on the drum. If however the cable is being pulled out of the hoist

at an angle, it may not engage with the safety bar, so caution is needed in

this situation.

2. In order to prevent the motor/gearbox from overheating, the hoist

should not be operated for longer than four minutes at any one time. Any

period of use should be followed by a similar period with the hoist at rest.

3. Do not wind loose cable onto drum - ensure that cable is always under

tension.

DO NOT use more than one hoist to lift a load.

DO NOT leave the hoist unattended with a suspended load.

DO NOT wrap the hoist cable around the load.

DO NOT use the hoist to lift dangerous materials.

DO NOT use the hoist to lift people.

Use a qualified person to lubricate and maintain the hoist.

When not in use and before carrying out repairs/maintenance isolate the hoist from the

power supply.

DANGER! Ensure that personnel are prevented from passing beneath the hoist and load.
