double girder electric overhead traveling crane Q235B steel
materialsLH type Double-girder electric hoist bridge crane is a new
type of double-girder bridge crane. Based on the introduction and
digestion of foreign advanced technology, our company takes the
modular design theory as the guide and modern computer technology
as the means to introduce optimized design and reliability. It
adopts the unique design method, adopts imported configuration, new
materials and new technology to complete the new crane with light
weight, generalization, energy saving and environmental protection,
and high technology content. The hoisting mechanism of this type of
crane is a fixed electric hoist in the form of CD/MD/HC.The design,
manufacture and inspection of this crane all comply with the
relevant national standards, and equivalently adopt some foreign
standards such as FEM, DIN, and IEC. The core components of the
transmission mechanism,the reducer, are all made of hard-toothed
surfaces and high-precision gears. The pair plus the application of
steel drums, forged wheels and frequency conversion speed control
systems make this type of crane a replacement for both economic and
social benefits crane.Application:LH type double girder electric
overhead traveling crane is suitable for general workplaces,
the working environment temperature is -25~40°, the
working duty is light, and it is not suitable for heavy
workshop work. Usually used in machinery manufacturing, assembly,
petrochemical, warehousing and logistics, power construction,
paper-making, railways industry, etc., where the lifting
frequency is low or the rated lifting tonnage is small and the
number of lifting times is small.Features at a glance:Compared with
the general QD type double-girder bridge crane, LH type crane
has the advantages that the self-weight is reduced by about 15-30%,
and the wheel pressure is reduced by about 10-35%, which can reduce
the crane's requirements for the plant structure and save plant
manufacturing costs in the early stage of construction.(1)The
main beam adopts the off-track box structure, and the end beam is
connected with high-strength bolts, which is convenient for
transportation. Specialized processing equipment ensures the
connection accuracy of the main and end beams and makes the crane
runs smoothly.(2)The hoisting trolley is an open and compact
hoisting structure, and European-style hoist trolleys can also be
used for medium tonnage according to
customers' requirements.(3)The running mechanisms of the
trolley and crane adopt the European technology three-in-one drive
form, and the hardened surface reducer has a compact structure with
low noise, no oil leakage and long service life.(4)Due to the use
of European-style compact trolley and high-strength materials, the
overall crane is small in size and light in weight. Compared with
QD type traditional crane, the height of the plant can be reduced
under the same lifting height, which effectively reduces the cost
of the plant.(5)Modular design, short design cycle, high degree of
generalization, and improve the utilization rate of
parts.(6)Compact structure, low headroom, small size, large working
range, effectively improve production efficiency.(7)Full frequency
conversion control, stable operation, no impact, slow speed for
heavy load, fast speed for light load, energy saving and
consumption reduction. Product specification:Electric hoist
