80ton Heavy Duty Double Girder Gantry Cranes For Granite And Marble Stone Lifting

80ton Heavey Duty Double Girder Gantry Cranes For Granite And Marble Stone Lifting

General Introduction:

Double girder electric gantry crane 80 ton are made up of bridge, trolley, crane traveling mechanism and electric system.All the procedures are finished in the operating room. Applies to the open warehouse or rail along for general handling and lifting work. Also can equipped with many lifting device for special work. Prohibited for lifting high temperature solution, flammable, explosive, corrosion, overloading, dust and other dangerous operations.

Detail Features:

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.
