Telescoping Light Crane System

The telescoping light crane system is a suspension crane whose girder can be pulled out sideways beyond the runway. It is used when the load has to be picked up or set down outside the area covered by the crane tracks: inside a machine, on a truck or in a container, next to an assembly line or across an aisle.

The crane girder is built in two levels. The upper girder travels on the runway like a normal single girder light crane. A second beam carrying the hoist runs on trolleys underneath it and slides out to one side. When the work is done the beam is pushed back, so nothing projects into the neighbouring area or blocks a traffic route.

A fixed girder overhang is limited to a few hundred millimetres, because a longer cantilever would tip the crane under load. The telescoping beam reaches up to 1.3 m beyond the runway with loads of 125 kg, 250 kg or 500 kg.

Hoisting is normally electric, while crane travel and the extension are moved by hand. On aluminum rail systems a spring balancer can be fitted that pulls the extended beam back to its home position automatically.

Standard sizes

Span, girder length and extension are engineered for each project. Send us the load, the required reach and a sketch of the building for a layout.

1. Reaches beyond the runway
The hoist travels out past the crane tracks to places a normal suspension crane cannot serve.

2. Retracts when not in use
The beam slides back under the girder and leaves aisles, doors and neighbouring cranes clear.

3. No extra steelwork
The working area is enlarged without extending the runway or adding columns.

4. Easy manual operation
The extension runs on the same smooth internal trolleys as the crane itself.

5. Automatic return option
On aluminum systems a spring balancer brings the beam back to its home position.

6. Part of the modular system
Uses the same tracks, suspensions and hoists as our single girder light crane systems.

Typical uses for the telescoping light crane system:

1. Loading and unloading machine tools, presses and furnaces from the side.

2. Loading trucks and containers from inside the building.

3. Feeding an assembly line or conveyor that runs outside the crane runway.

4. Passing loads across an aisle or between two neighbouring crane bays.

5. Tool and fixture handling in automotive production.
