Double Girder Grab Bridge Crane for Lifting Scrap in Steel Mill Factory

Bridge cranes are high-capacity FEM class heavy duty cranes that can meet customer demands in iron and heavy industrial plants or energy sectors. These cranes are specially designed for customer satisfaction and they are designed with high engineering techniques.

General descrption:

Two girders are simply stronger than one, making double girder traveling cranes the ideal solution for the area coverage handling of heavy loads up to 32/5t. Like all factory cranes, these units are available with a number of main girder connection versions to best suit new or existing buildings and the best in functionality, versatility and convenience. double girder cranes feature welded box beams. All the sections used for main girders and end girders are computer-optimized for high performance and low weight, benefits that pay in terms of strength and cost efficiency.

Mechanical feature:

Double welding box girder, DIN/FEM standard deflection.

Material Fe37 or Fe52.

Whole length CNC cutting for complete web plate, high deflection accuracy.

Trolley rail is high strength flat steel bar (hot rolled ,16Mn).

High quality automatic welding and NDT inspection.

Shot-blasting Sa2.5 for complete girder after welding, stress release.

Epoxy zinc rich high quality painting, 2x2 with 140μm.

10.9 class High tension bolts mounting between girder and legs, life time safety connection.

Compacted gear motor driving, continuously variable control, harden gear, safety disc brake.

High protection class IP55, F class, 40% ED.

Double flange or flat wheels, anti-friction bearings, cellular buffers, derailment protectors.

Full-length service platform along the crane bridge is supplied,where it is equipment with protective hand railing and toe strips.

Electrification and outfitting:

Conductor power supply.

Phase control guard opens the main contacts in case of phase failure.

All hoist and crane movements are independent and can be run simultaneously.

Contacts meet crane applications, rated for severe vibration.

The control panels are finished to withstand corrosion, IP55.

Heavy duty plug head.

The components are positioned in a maintenance friendly way, and the whole layout provides good protection against accidental contact.

The integrated plug type fixed cables with plastic insulation are intended for crane usage.

Cables are coded either with numbers, colors or tags for easy identification.

The flat cables used for festoons are PVC insulated flexible flat cables rated for 450/750V, specially designed for cranes, hoists.

Festoon cables are suspended on cable saddles, fixed to cable trolleys, running in a galvanized C-track, which is connected to the main girder with bolted or welded support brackets.

Application:

It is specially fit to the areas of dense equipments, transportation in short distance, telescopic beam crane system and high work frequency.
It is vastly used in the following industries, aerospace industry, Auto-mobile, ship building, electronic assembly, food-production, mechanical production, warehouse, etc.
