    1 Safety instructions 1.1 Symbols In these operating instructions, the following symbols indicate particularly important information on risks and safety in operation. Safety at work This symbol marks all information on safety at work where risks to life and limb are entailed.

  • Page 5: Use For Intended Purpose

    1 Safety instructions 1.3 Use for intended purpose • Chain hoists are intended for lifting freely movable and guided loads that cannot tilt. Depending on their design, they are for stationary or mobile use. If loads are to be towed horizontally, or in the case of guided loads, automatic operation, continuous deadweight or constantly repeated hoisting motions, the individual application must be assessed.
