then match them. The application, environment it is to be used in, the size and type of load, the
attachments to be used and the period of use must also be taken into consideration in selecting
the right chain block for the job.

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 +80°C (+176°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.
