Indoor Use Bridge Type Single Beam Travelling Crane For Iron And
Steel Plant 3T
Description of single girder overhead crane
1, LD type electric single beam crane is designed and manufactured
according to JB/T1306-94 standard, its main beam structure form has
I-steel main beam, box main beam and flower frame main beam
structure, with reasonable structure, the rigidity of the whole
machine is strong.
2, LD type electric single beam crane and CD1 type, MD1 type
electric hoist supporting use, electric hoist hanging on the main
beam I-steel or the main beam under the edge, its lifting weight is
1T-20T, span is 7.5-28.5m, the working level is A3-A4, the working
environment temperature is -25℃ ~ 40℃.
3. LD type electric single-beam crane is provided with two
operating forms: ground and control room.The ground operation
usually adopts the operation mode of handle button and remote
control.Operation room and open type and closed two, according to
the situation can be divided into left and right installed two.
4. LD type electric single-beam crane usually USES conical brake
motor for lifting and operation, and gear reduction device for
transmission;The whole machine is equipped with lifting, lowering
limit switch, trolley travel switch, handle button, overload
limiter and other accessories.
5. LD electric single-beam crane is widely used in factories,
warehouses, material yards and other occasions to lift goods. It is
prohibited to use in the environment of inflammable, explosive and
corrosive media.
6. Electric single-beam crane with low headroom structure can
effectively raise the lifting height;The construction cost can be
greatly reduced through the reasonable design of girder structure
and the selection of suitable girder structure.

2) Light duty
3) Stronger structure
4) Safe traveling
5) Fluent starting and stopping
6) Noise-less
7) Good appearance
8) Easy and convenient maintenance
Details of Single Beam Girder Overhead Crane:
Metal schemes
The main beam is made of U steel rolled by steel plate, and welded
with flange beams to form a box design.
The end beams are made by the same technique and material as the
main beam.
In case of heavier load or larger span, the end beams and main beam
will be made of welding U shape groove.
The main and end beams are connected by intensive bolts for
convenient transportation and assembling.
Electric hoist
The LDA model crane adopts CD or MD type hoist. CD type has single
speed while MD type has dual speed to satisfy accurate operation.
The travel unit
This crane is driven in two separate ways. The cone shape braking
motor or solid rotary motor (with magnetic brake) is the driving
part.
While the transmission part is “ open-close” gear, and the close
gears are LDA or LDH gear box.
Electric devices
The motors are cone-shape cages ZDY, or YSE solid rotary ones.
These two types have different electric control system.
The hoist and the crane are protected by safety devices, such as
lifting limit switch, terminal limit switch, over load limit, wrong
phase and over current protection etc.
Applications:
Packing and shipping of single girder overehad crane
