2.1 Critical Installation Considerations
2.2 General
Radio-controlled material handling equipment operates in several directions. Cranes, hoists, lifting devices and
other mobile hydraulic equipment can be large, and operate at high speeds. Quite frequently, the equipment is
operated in areas where people are working in close proximity to the material handling equipment.
The operator
must exercise extreme caution at all times.
Workers must constantly be alert to avoid accidents. The following
recommendations have been included to indicate how careful and thoughtful actions may prevent injuries, damage
to equipment, or even save a life.

Only properly trained persons designated by management should be permitted to operate radio-controlled
equipment.
Radio-controlled cranes, hoists, lifting devices and other mobile hydraulic equipment should not be operated by

Radio-controlled equipment should not be operated by any person with insufficient eyesight or hearing or by any
person who may be suffering from a disorder or illness, is taking any medication that may cause loss of equipment
