3.3.3 Determining the operating group of the hoist
When the load spectrum and the average daily operating time of the hoist are identified, the hoist's
operating group is obtained from the table below.

3.4 Safe working principles
Carefully following safe working principles is one of the most effective ways of preventing damage to
property and injury to personnel. The operator, serviceman and work manager for the hoist should be
familiar with the safe working principles for the hoist. A service organization authorized by the
manufacturer can provide training for operating the hoist and any maintenance services needed under a
separate agreement.
Misuse of the hoist or improper servicing may result in an accident that cannot be prevented by the safety
equipment. Crane Operator, operation and safety training will introduce the operator to the essential safe
handling of loads with the hoist equipment and safety procedures to follow. Service training can also
provide the preventive maintenance requirements of the hoist to prevent equipment failure effecting
production and/or safety.
Work management has an important role in implementing the principles for using the hoist safely. Work
management must ensure that the hoist and its accessories are fit for the intended purpose, and that
servicing and maintenance of the equipment is carried out as scheduled. Management must also ensure
that personnel are adequately trained in the safe operation of handling loads.
!
The hoist operator, the hoist serviceman and personnel in charge of hoist operation and
servicing shall be familiar with and comply with the safe working principles described in the
instructions.
!
Read all safety instructions supplied with products.

Study meaning of stickers on products.
3.5 Using the pushbutton controller
The hoisting and travel motions of the hoist as well as crane travel motions are controlled with the
pushbutton controller or by remote control. Some pushbutton controllers and remote control units are
provided with a selector switch that allows the same controller unit to be used to control several hoists
and/or cranes. If the hoist has remote control (infrared or radio control) separate operating instructions for
the remote controller are provided with the hoist. The direction symbols on the pushbutton controller
conform to local requirements.
