Function/Operation

! WARNING
If parts of the hoist are dropped, they can cause injury, death or property damage. Adequately support the hoist during
installation.
Hand operated manual chain blocks are actuated by pulling on the hand chain that is fitted to a pocketed wheel that when
rotated acts on the brake and either raises or lowers a load.
The hoist may be used at ambient temperatures between -40°C (-40°F) and +50 °C (+122 °F). Consult the manufacturer in the
case of extreme working conditions.
Note: Before use at ambient temperatures of less than 0°C, check the brake for freezing by lifting and lowering a small load 2 -
3 times. Before operating the hoist in special atmospheres (high humidity, salty, caustic, alkaline) or handling hazardous
goods (e.g. molten compounds, radioactive materials), consult the manufacturer for advice.
Loads can be moved horizontally with the use of a trolley. Always transport the load in the horizontal direction slowly, carefully
and close to the ground. Alternatively, refer to the section on cross hauling (Chapter 4)
Operation
Face the hand chain wheel side of the hoist.
Lifting the load
Pulling the hand chain in clockwise direction will raise the load.
Note: Depending on the type of load picked up, the lifting height may be reduced for units fitted with a chain container.
Lowering the load
Pulling the hand chain in anticlockwise direction will lower the load.
Note: The clicking sound of the pawl when a load is being raised indicates normal operation.
On TCB hoists with two chain block heads, use two operators, one on each of the two hand chains. To keep the load chain
centred in the block assemblies, operate the units simultaneously and at the same speed. An equal amount of unloaded chain
must be maintained under each hoist body.
! WARNING
Stop operating in the lifting direction when the hook block contacts the hoist body, as noted by the sudden increase in the
hand chain pull or the tipping of the hook block.
The operator must ensure that the hoist is suspended in a manner that makes it possible to operate the unit without
exposing himself or other personnel to danger by the unit itself, the suspension or the load.
Stand clear of all loads and avoid moving load over the heads of other personnel. Warn personnel of your intention to
move a load in their area. When the unit is not in use, position the suspension (e.g. bottom block, load hook) above normal
head height, if possible.
Do not allow load chain on hoists with two chain block heads to accumulate on one side (under one hoist body). Excessive
loading to load chain anchor may occur resulting in a falling load which can cause death, injury or property damage.
