Top Quality Factory Steel Project Gantry Crane
Top quality factory steel project gantry crane is used both in
multi-wind area and workshop for inside & 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 & is characterized in
the light dead weight and strong lift capacity. It has
ground-controlling and remote-controlling. The lifting capacity is
2~20t, span is 10~30m, 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.
Design: ‘WEIHUA’ 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.
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.
Independent Hydraulic Brake make the crane safer and easier to
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.
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.
Modular design, ease to install and maintain, reliable operation,
fuse less circuitry, ducted wiring and compact terminals. Motor
overload protection to prevent overloading.
Safety limit switches for stoppers will be provided to prevent over
traveling in all motions.
Two coats of primer before assembly & two coats of synthetic
enamel after testing.
Variable speed through VVF Drive
Wireless Radio Remote control
Shrouded DSL system for power feeding
Crane hook block
The rope sheaves are fully guarded with protective steel casting.
All sheaves rotate on ball bearing. The pulley is thicked and
dilated than domestic common pulley.
