Advantages of Double Girder Gantry Crane:

· Because gantry cranes ride on the ground rather than on overhead runways, they don't require a runway structure.

· Nor do they usually require concrete foundations.

· Their installation is fast and simple.

· Gantry cranes sometimes can provide a significant cost saving than bridge crane accodring to the environment.

· Simple and compact structure

· Light weight

· Steady performance

· Easy maintenance

· Less wastage

Electric Trolley Lifting Mechanism:

· DESIGN: Compact dimensions, low weight, easy to operate and easy to maintain, modular design with direct fits between components.

· MOTORS: Axon uses sturdy cylindrical / conical rotor pole-changing motors with elegant continuous cast aluminum sections, integrated safety brakes insulation class F, IP54 protection.

· GEAR BOXES: Precision flat helical / spur gear units in light alloy housings with case-hardened gears, high-grade surface treatment and permanent oil / grease lubrication.

· BRAKES: Single / Dual-disc electromagnetic DC brakes featuring automatic braking on power failure. Environmentally sound brake linings designed for approx. 1 million braking operations allow long maintenance intervals.

· ELECTRICAL PANEL: Modular design, covering a very wide operating range. The systems are designed for ease of installation and maintenance and reliable operation, with fuse less circuitry, ducted wiring and non-screwed terminals. Each drive group is equipped with a motor overload protection device to provide effective protection against inadmissible overloading.

· PAINTING: Every component & part is thoroughly scrubbed & painted with two coats of primer before assembly & two coats of polymer based quick drying acrylic polycot paint after testing.
