Half 4 Meters High Light Semi Gantry Crane High Herformance
This semi gantry crane is a general purpose light crane used in
workshop or outdoors. The leg height of this single girder
semi-gantry crane can be different according to the engineering
needs on the construction field. The semi gantry crane has the
features of simple structure, easy installation, light weight, good
wind resistance. The Main girder is mostly bias rail box type
structure. Compared with the double girder gantry crane, the
lifting capacity is smaller, generally ≤50t, and the span ≤35m.
Semi gantry crane can be used with CD1, MD1 hoists. It can be
remote control and floor control.
Depending on the environment and application, gantry cranes can
sometimes provide the same material handling capabilities as a
comparable bridge crane system, but with a significant cost

Safety Protection of Half 4 Meters High Light Semi Gantry Crane:
1. Overload limiter;
2. Polyurethane buffer, long service life and impact resistance;
3. Crane travelling limit switch;
4. Loss pressure protection, fault phase protection;
5. Emergency stop system;
6. Lifting height limiter;
Motors: The motors are used special 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.
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,
fuses less circuitry, ducted wiring and compact terminals. Motor
overload protection to prevent overloading.
