MZ Type Double Girder Grantry Crane With Grab Cap.5~10t

MZ Type Double Girder Grantry Crane With Grab is widely used in ore, limestone, coal, sand and other granular material in the warehouse.I t is a heavy duty working system, an ideal crane with high efficiency, and full functions; the lifting capacity includes the weight of the grab.  Electric grab can be used to capture granular materials, such as ore, sand, carbon stone, slag, coke, coal, loose clay, etc.
All operation is completed in the driver’s chamber. If clients have special requirements, our company is able to carry out design and production of non-standard equipment.
 

The double girder cranes are used when heavy loads, wide spans or high working frequency are required than single girder gantry crane. Double girder gantry cranes consist of two torsion-free box girders and four legs to achieve perfect construction stability. This makes double girder gantry cranes especially suitable for lifting and transporting loads over 10 T and for span of more than 25m,load capacities up to 500 T and with spans up to 50 M.

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

Standard Features:


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 antifriction 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 technic) ) 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.

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