Product Description   

LH type Overhead/Bridge Crane with Electric Hoist

Brief Introduction 
LH double girder overhead crane systems with trolley  is the most popular crane for all types of workshop.                 
It is composed of box type bridge frame, lifting trolley, crane traveling mechanism and electrical system. 
It employs fixed electric hoist, which is fitted on trolley frame as the hoisting mechanism.  
It could be used in mechanical processing workshop, metallurgical factory and subsidiary workshop,  warehouse, material yard and power plant for transferring, assembly, inspection maintenance and  loading procedures.
It can also replace common overhead crane, used in light textile industry and food industry manufacturing Workshop.

Components
Crane girder: 
The crane girder is of welded girder construction. This result in lower dead weight with a high degree of  vertical and horizontal rigidity and small wheel loads being transmitted to the crane runway!  
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 more safe 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 anti friction type  ball / roller bearings in totally 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 tech) which make 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. 
Optional Features: 
Variable speed through VVF Drive 
Soft starter 
Slipring motors 
Wireless Radio Remote control 
Shrouded DSL system for power feeding 
Flameproof

Looking forward to receive your enquiry with the below details information: 
1. lifting capacity. 
2. span length. (cantilever length)
3. lifting height. (hook center to ground)
4. Power supply: Voltage. 
5. Do you need rails? How long is the crane traveling distance? 
6. Working condition: which material to lift? temprature? 
7. Would be better if you have drawings of your plant.
