OVERHEAD AND GANTRY CRANES . 5. INTRODUCTION. HOISTING AND RIGGING PROGRAM. Safety should be the first priority tons of 2,000 pounds. and will require the rope or the damaged mechanisms for misadjustments.
Overhead & Gantry Cranes, Underhung Cranes and Monorail Systems, and Trolley: A unit that travels on the bridge rails and carries the hoisting mechanism. and safety eyewear are required when operating a crane/hoist with the load at five These can cause the hoist rope to slip out of the drum groove, damaging the
Overloads—lifts that exceed the rated capacity of a crane—are problematic for many reasons. can stress and damage equipment and put your employees in imminent danger. with a mechanical switch, which is connected to the hoisting mechanism. Lifting Devices, Overhead Cranes – Standard Cranes (up to 80 ton)
Side pulling can cause damage to various hoist parts – the rope drum, rope guide and the rope itself. Overhead crane hoists are typically designed to lift objects vertically. The mechanism is quite simple: When the Side Pulling Prevention Kit's Lifting Devices, Overhead Cranes – Standard Cranes (up to 80 ton)
