Hoist Trolley
Gorbel’s hoist trolleys provide the connection between the lifting device and the bridge. The trolleys are designed for effortless movement along the bridge. The stamped body fits most rigid hook or eye lifting devices.
Wheels are tapered to match the 2° taper of the track. This reduces rolling resistance and wheel wear. Wheels contain ball bearings that are sealed and lubricated for life.
End Trucks
Gorbel end trucks provide the connection between the bridge and runways.
They are designed for effortless movement along the runway.
Wheels are tapered to match the 2° taper of the track, which reduces rolling resistance and wheel wear. Wheels contain ball bearings that are sealed and lubricated for life.
Two horizontal wheels center the end truck within the runway which prevents binding of the bridge. As a result, the position of the load on the bridge has little effect on the amount of force needed to move the bridge along the runway.
Any slight runway track misalignment is taken up by the bridge floating in one end truck, while the other end truck is firmly clamped to the bridge.
Extended End Trucks
The extended end truck is designed for longest bridge lengths and helps evenly distribute the weight of the load to maintain easy bridge movement and prevent binding.
Festoon Trolleys
Gorbel festoon trolleys (optional) are used to support flat cable or air hose along the runway or bridge.
The trolleys have four wheels and a pivoting festoon saddle support. They are ideally suited for long runways (greater than 19m) or with round cable or air hose.
With runways greater than 19m or with an all aluminium system, festoon trolleys are standard. Special festoon trolleys for vacuum hose are also available.
Festoon Gliders
Festoon gliders are used to support flat cable along the runway and bridge and they are standard on steel runways of 19m or less.
No tools are required to attach the festooning to the gliders.
Festoon Clamps
Festoon clamps anchor the festooning at the start of the runway and bridge.
They also prevent the festoon gliders from exiting the track and they can provide a redundant stop for the end trucks and trolley.
Festoon tow clamps are also available for systems with standard end trucks.
End Stop Bumpers
High-impact moulded end-stop bumpers are provided on all runways and bridges to prevent the end trucks and trolley from exiting the track. The bumpers are bolted to the track to physically limit the travel of the end truck and trolley.
Festoon Stack Section
A stack section at one end of a runway serves as an extension that allows festoon carriers to be stored on the end of the runway without reducing crane coverage.
Flat Cable and/or Air Hose
A flat cable festooning system is included in all Gorbel Work Station Bridge Cranes.
Plenty of cable is provided for 1m loops on the runway and 500mm loops on the bridge.
Optional air hose is also available and is supported by optional festoon trolleys.
Gorbel Work Station Cranes can utilize optional conductor bar electrification, but this results in an increase up to 40% of the amount of effort required to move the system.
