2 Critical Installation Considerations
2.1 General
Radio-controlled material handling equipment operates in several directions. Cranes, hoists, lifting devices
and other material handling equipment can be large, and can operate at high speeds. The equipment is
often 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, prevent damage to equipment, or even save a life.
