Gantry Cranes C30/31
DESCRIPTION
Unit Standard SAQA Reg. No 242976)
What is a Gantry Crane? A gantry crane is a crane built atop a gantry, which is a structure used to straddle an object or workspace. They can range from enormous “full” gantry cranes, capable of lifting some of the heaviest loads in the world, to small shop cranes, used for tasks such as lifting automobile engines out of vehicles. They are also called portal cranes, the “portal” being the empty space straddled by the gantry.
However a gantry crane is similar to a bridge crane, but instead of moving on suspended runways, the crane uses legs to support the bridge, trolley, and hoist. These legs travel on rails that are embedded in, or on top of the floor or ground structure.
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 gantry cranes by untrained persons.
Successful candidates credited with this unit standard are able to:
- Demonstrating knowledge of the functions of a crane.
- Identifying the safety and suitability of the crane type prior to utilization.
- Inspecting and recording the operational fitness of the components of a crane.
- Operating an overhead crane in a safe and competent manner.
- Accessing available support systems and emergency services in case of incidents and accidents
