DOUBLE BEAM GANTRY CRANE

TECHNICAL CHARACTERISTICS

Structures
The master girders, legs, and connections, are welded structural steel plate material, reinforced by diaphragms and cross bracings. A gangway can be provided, on request, along one of the master girders.

Longitudinal travel
Properly dimensioned steel wheels running on roller bearings. Movement for high lifting capacities and large size cranes is achieved by means of double wheel articulated carriages.
Only highest quality casehardened and temperated oilbath gearboxes are used.
On request an inverter is available in order to have soft start, tht prevents dangerous load swingings.
It is installed on any crane gearmotors directly coupled on the wheel (very low maintenance).

Lifting and trolley
For single girder cranes a high quality hoist-trolley runs along the girder lower flanges, while double girder cranes are supplied whit a structural box crab, produced by ourself, which runs on four steel wheels rotating on roller bearings. Lifting winding drum directly splined on its gearbox. Electro-hydraulic shoes brake on the lifting movement.
Motor and gearbox fixing bases are manufactured by numerical control machine in order to assure the perfect ranging among the components.

Electric equipment
• Placed in a water tight metallic cabinet with high quality components.
• Double safety limit switch is mounted on the crab lifting movement.

Control
Usually controlled by means of low-tension pendant push-button panel. Remote control also available on request.

Painting
Steel structures are mechanically brushed, chemically degreased and protected with two coats antirust primer and one enamelled coats. Sandblasting on steel works is available on request.

Every machine is designed according to the customer requirements.
