Brief introduction of double girder gantry crane

The double main girder gantry crane has strong bearing capacity, large span, good overall stability and many varieties, but its own quality is larger than that of the single main girder with the same lifting weight, and the cost is also higher.According to the main beam structure, it can be divided into two types:Box beam and truss.Generally, a box-shaped structure is used.

ProductionConfiguration & production technology

Beam	High technique, torsion-free box girders, no welding one whole type, strong and beautiful
Electrical parts:	Siemens brand/Schneider brand
Motors	Frequent starting , reversing & braking, dust proof construction foot / flange mounted TESC / TEFC , Sq.Cage motors with integrated safety brakes, insulation class F, IP54 protection for hoisting, CT & LT motions.
Brakes	Independent Hydraulic Brake
Gear Box	Accurate hob cut helical / spur gears & pinions having hardness 250 to 350 BHN made from carbon alloy steel, smooth operation & long life, can equipped with SEW/ABB brand high quality gear box
Electrical Panel	Modular design, ease to install and maintain, reliable operation, fuses less circuitry, ducted wiring and compact terminals.Motor overload protection to prevent overloading If cabin control, it can be equipped with Air-conditioning and with easy and conveniet control panel.
Limit Switch	Safety limit switches for stoppers will be provided to prevent over traveling in all motions
Safety feature	Overload protection.Main lifting motor with thermal protection.Hooks with latch.Rubber buffers.Protective earthing.Crane switch and travel end switch.Emergency switch can stop all movement when any dangerous happened.Sub-assemblies characteristic are tested before assembly.All cranes must be pre-assembled and tested before leaving factory and offer the certification of test

Features and Advantages:
1) Reasonable structure
2) Favorable performance
3) Smooth starting and stopping
4) Safe and reliable traveling
5) Low noise, commodious cabin and good view
6) Convenient maintenance, excellent exchangeability for parts and components
7) Energy saving,reduce energy consumption
8) Using transducer for travelling or traversing crane to realize step speed or stepless speed change
9)Primer and finishing paint
10)Crane structure:Steel box type
