Overhead Cranes-Pendant Controlled C30

DESCRIPTION

Unit Standard (SAQA Reg. No 116235)

What is an overhead crane? Commonly called a bridge crane, and is a type of crane found in industrial environments.

An overhead bridge crane is a configuration of a single girder or double girder design. In simple terms, a bridge girder, or beam, is the support structure that allows the operator to move trolley and hoist from side-to-side along the bridge. The trolley is used to precisely position the hoist prior to raising or lowering a load in a safe work manner.

A crane can be controlled by an operator on the floor using a push button pendant system that is attached to the crane itself, or a wireless control that utilizes a radio transmitter and receiver.

Unlike mobile or construction cranes, Pendant controlled overhead cranes are typically used for either manufacturing or maintenance applications, where efficiency or downtime are critical factors.

If a crane operator is trained properly, pendant and radio controls can both be perfectly safe methods for controlling and operating a crane. Training is a vital issue and DMR 18(11) prohibits the operation of Overhead cranes by untrained persons.

Successful candidates credited with this unit standard are able to:

  • Demonstrate knowledge of the functions of a pendant controlled overhead crane
  • Identify the safety and suitability of the crane
  • Apply the recognized methods for inspecting and recording the operational fitness of all components of the crane
  • Operate a pendant controlled overhead crane
