Heavy Duty Double Girder Gantry Crane Used In Automobile , Construction And Engineering Industries
General Introduction
Gantry crane 50 ton s are self-pushed cranes running on rails introduced at ground level. GANTRY CRANES are additionally alluded to as GOLIATH CRANES. GANTRY CRANES/ GOLIATH CRANES are utilized for overhead materials taking care of where existing segments don't have overhead sections to underpin gantry & rails. GANTRY/ GOLIATH CRANES are regularly utilized within open zones where sections can't be suited. The top principle brace is mounted on two A shape segments which are further resting on wheel mounted closure carriages. These finish carriages have wheels which run on rails which are grouted to the ground.
These GANTRY CRANES/ GOLIATH Cranes could be seen working in open mixes of concrete plants, throwing of concrete braces for scaffolds/ flyovers. These GANTRY CRANES/ GOLIATH Cranes are likewise seen being broadly utilized within substantial creation yards.
The design and manufacture follow the GB/JB standard

3. Easy to Operation, Precise Position, More Safety
LIMIT SWITCHES – To prevent over hoisting & over lowering of hook.
PUSH BUTTON STATIONS – Extra light, handy, easy to operate. Wireless Radio remote controls are also conveniently and widely being used now.
SOFT STARTS – Electric / Electronic soft start modules electrically coupled to the long travel drives to achieve jerk free, cushioned & smooth starts.
MAINTENANCE PLATFORM WITH HAND RAILING – Easy, simple & safe maintenance of the Crane extended partially or along the full length of the girder.
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.
