ELECTRICAL SAFETY
Ensure that you check the equipment thoroughly to ensure it is safe
and fit for purpose before each use. It is important that you inspect
all plugs, sockets, power cables and electrical fittings for wear and
damage and repair or replace any defective components. The risk of
electric shock can be minimised by the correct use of the appropriate
electrical safety devices. We recommend that you fit a Residual
Current Circuit Breaker (RCCB) in the main distribution board and
that a Residual Current Device (RCD) is used when operating this
equipment.
The Electricity at Work Act 1989 includes legislation that places legal
implications on employers to ensure the safety of electrical devices in the
workplace. The regulations dictate that all portable equipment must be
inspected regularly and tested to ensure that it is safe for use. 'Portable
equipment' means any electrical item that can be moved and this is often
referred to as Portable Appliance Testing (PAT). PAT testing should be
carried out regularly on this equipment by trained, authorised personnel, as
required by the legislation.
The Health and Safety at Work Act 1974 states that it is the responsibility
of the owner of electrical appliances to ensure that both the equipment and
working environments are maintained to ensure safe operation at all times.
Check that all equipment power cables are secure, correctly insulated,
free from damage, and protected against short circuit and overload before
connecting to the power supply. Do not use worn or damaged cables,
plugs, sockets or other fittings.
This equipment is supplied with
a BS1363/A UK 13 Amp 3-Pin
plug. Ensure that the power supply
matches the voltage requirements
specified on the equipment and
that the plug is wired correctly
and fitted with the correct fuse. If
the electrical fuse blows, ensure
it is replaced by an identical type
of fuse with the same rating. (See
Fig.2
)
Ensure the power cable is kept away from heat, oil and sharp edges. We
recommend that the equipment is connected directly to the power supply
without the use of extension leads as the resulting voltage drop can reduce
motor performance.
Always disconnect the equipment from the power source before servicing,
inspecting, maintaining, cleaning, replacing or checking any parts.
INSTALLATION
The hoist is fitted with a specially designed bracket system that allows it to
be fitted to a suitaby sized square box section beams as shown in (
Fig.3
below).
The hoist can be configured with a single or double cable setup depending
on the weight of load you need to lift.

OPERATION GUIDE
BEFORE LIFTING
:
Before beginning to operate the machine, ensure that the steel
cable is correctly wound on the spool and the pitch is equal to
the cable diameter. Leave at least 3 complete windings of cable
on the hoist, to avoid damage to the cable fixing. (See
Fig.4
).
Fig.4
Correct Cable Spool Winding
Press the lift button before loading to eliminate any slack in the
steel rope, before lifting the load. Avoid winding over 15m of
cable on the hoist.
IMPORTANT:
In an emergency press the emergency
stop button to halt the hoist. To release the emergency
stop button, turn it clockwise.
LIFTING
:
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.
2.
With mains power switched on, operate
the Lift-Lower Control Switch to bring the
hook to load height. Press the lower half of
the control switch to lower hook and upper
half to raise hook. Release the control switch
to stop hoist.
3.
Attach the lifting hook to the load, ensur-
ing that safety bar is fully closed.
4.
Use the control switch to raise or lower
the load to the required height.
DOUBLE LINE LIFTING
:
To carry out a double line lift, first hook the single line hook in the hoist
aperture. Then take the double line pulley and hook, remove the ‘R’
pin, shaft and washers and undo nyloc nuts and remove the small
bolts. Place the pulley on the cable loop between the 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 with the lifting procedure
outlined above.
IMPORTANT:
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.
Do not wind loose cable onto the drum - ensure that
cable is always under tension.
