Tractel Tralift Manual De Empleo Y Mantenimiento página 4

1. DESCRIPTION OF THE HOIST
The tralift™ is a portable manual hoist for lifting which can be used on a fixed lifting point or with
suspension trolleys. Information about suspension trolleys can be obtained from TRACTEL
request.
Using a double spur gear mechanism the tralift™ has been designed to give optimum working
efficiency, to be light and to require only a short headroom.
tralift™ is supplied with ISO grade 80 load chain for a lifting height of 3 metres as standard. An optional
load limiting device is available and further information can be obtained from TRACTEL
2. INSTALLATION
Before installing the tralift™ make the following checks:
2.1. Check that the hoist is in good condition.
GB
2.2. Check that the correct capacity hoist is to be used.
2.3. When using a hoist with 2 or more falls of load chain ensure that there is no twisting.
2.4. Check that the load chain is correctly fitted with the link welds on the outside of the load
sheave especially when lifts other than the standard 3 metres are used.
2.5. Check that the anchor point is sufficient to take the intended load.
Once these checks have been carried out and the hoist is installed on its anchor point the following
procedure should be carried out before any work commences :
2.6. Check that the hoist is correctly attached to the anchor point and the top hook safety catch
is closed.
2.7. Check that the load chain has not become twisted during installation.
2.8. Without load check that the up and down functions operate correctly.
2.9. 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.
ATTENTION: The user should check that :
3. OPERATION
The tralift™ chain hoist is operated by means of a hand chain which is pulled by the operator to lift or
lower a suspended load.
With the handwheel casing facing towards the operator the following procedure actions lifting and lowering:
3.1. To lift pull the right hand chain.
3.2. To lower pull the left hand chain.
It is not recommended to pull the hand chain at excessive speed as this will lead to an uneven
movement of the load. It is recommended to pull the hand chain in a steady movement to prevent any
unnecessary jerking of the load.
4. REMOVAL FROM SERVICE AND STORAGE
When taking the hoist out of service ensure that any load is placed safely and securely on the ground
and that the load chain is slack enough to enable the bottom hook to be removed from the load.
It is recommended that the hoist be stored hanging so that the load chain does not become tangled.
Store the hoist in a dry and weather-proof area. Before storage clean the load chain with a brush and
lubricate with machine oil.
The hooks and catches are in good condition.
The anchoring accessory of the load seats fully in the hook and does not
prevent the catch from closing (see illustration).
The load on the hoist is free to align itself with the machine's anchor point.
