Product Details

20 ton box girder monorail electric hoist gantry crane with cantilever

Design, Features & Specifications:Traveling rail crane, light crane rail is the best light crane, which is used both in multi-wind area and workshop for inside and outside. It is composed of metal structure, cart operating mechanism, electric device and trolley (electric hoist). The surface of facing wind is very small, because of its steel-pip leg, and is characterized in the light deadweight and strong hoisting capacity. It has ground-controlling and remote-controlling. The lifting capacity is 2~20t, the span is 10~30m, the ambient temperature is no more than 40°C, and wind-pressure is less than 125Pa.

 

The profiles of the main girder are optimally produced using an integrated technology which is weldless, so that maximum performance with a minimum of deadweight can be achieved.

Features

Brand MH model trussed electric hoist single beam gantry crane is designed & manufactured accordance with ISO 9001:2000 ISO 14001:2004 and OHSAS 18001 considering factor of safety in respect to appropriate class of duty.

Motors: The motors are used specially crane duty suitable for frequent starting , reversing & braking in accordance with ISO 9001:2000 ISO 14001:2004.Motors are totally enclosed in 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 make the crane safer and easier to control

Gear Box: The entire gear boxes are made of accurate hob cut helical / spur gears & pinions having hardness 250 to 350 BHN made from carbon alloy steel. All gears & pinions running on antifriction type ball / roller bearings in totally are enclosed oil bath giving constant splash lubrication. The helical / Spur gear designed for adequate strength and optimum wear resistance for smooth operation & long life.

 

Wheels: The wheels of crane crab, main beam and end carriage are produced in our special Vacuum casting workshop (No sand inclusion technique) which makes our wheels more elastic and outer surface hard-wearing and durable.

Electrical Panel: -Modular design, ease to install and maintain, reliable operation, fuse less circuitry, ducted wiring and compact terminals. Motor overload protection to prevent overloading.

Limit Switch: Safety limit switches for stoppers will be provided to prevent over traveling in all motions.

Painting: -Two coats of primer before assembly & two coats of synthetic enamel after testing.
