Product introduction:
LXB type explosion-proof electric single-beam suspension crane is used in conjunction with HB (BCD) and HBS (BMD) electric hoists to become a light and small crane that runs on rails.
Used in flammable and explosive places such as machinery, assembly and warehouses. This product is ground operation and remote control remote operation. Working environment temperature -25°c-+40°c. Used for working in flammable, explosive and corrosive medium environment
Product introduction of single beam suspension crane
The installation method of single beam suspension crane is that the
crane is hung on the I-beam fixed on both sides, so it is named
suspension. The single beam suspension crane has a large space
utilization rate because it does not use the column and other
foundation, and is suitable for the workshop with narrow space and
upper fixation. The single beam suspension crane is used together
with CD1 single speed electric hoist and MD1 double speed electric
hoist to become a kind of light and small crane with rail
operation. It is suitable for places where the height from the rail
surface to the bottom chord of the roof truss of factories and
warehouses is less than or equal to 500mm. The single beam
suspension crane is operated on the ground. The working environment
temperature is 25 ℃ ~ 40 ℃. It is forbidden to work in flammable,
explosive and corrosive medium environment. Lifting capacity: 1 ~
10t; Span: 7.5 ~ 22.5m; Lifting height: 3 ~ 30m
The structural features of single beam suspension crane are as
follows:
The bridge of single beam suspension crane is composed of main
beam, end beam and running mechanism; I-steel + channel steel
composite frame; There are three types of box girder, I-beam and
steel plate. The end beam is composed of channel steel, with simple
structure and convenient manufacturing. The end beam and the main
beam are connected by pin (small tonnage, small span) or fixed
welding (large tonnage, large span) as a whole, which is the main
body to bear the load. The running mechanism of single beam
suspension crane is composed of wallboard and running wheel. The
driving wheel group and passive wheel group are placed on the end
beam through double head screw, suspended on the lower flange of
I-shaped steel beam, and driven by motor through deceleration
mechanism, so as to achieve the purpose of reciprocating operation.
The electric hoist of single beam suspension crane is CD1 and MD1
type electric hoist designed by our country. The electric hoist is
a lifting machine with compact structure, which can complete the
lifting of heavy objects and run back and forth along the
longitudinal direction of I-beam. The electrical control of single
beam suspension crane is mainly completed by DK2 electric control
cabinet, which is easy to operate. The single beam suspension crane
is also equipped with lifting limit device and crane end travel
limit switch protection. At present, DHG type safety sliding
contact wire is mostly used in the crane guide wire of single beam
suspension crane to ensure the safe and reliable operation of the
crane.
Single beam suspension crane is a general purpose crane, which is
mostly used in low buildings and warehouses. It is the leading
product of single beam suspension crane in China in recent 20
years. The working environment temperature of single beam
suspension crane is - 25 ℃~ 40 ℃, and the relative humidity is not
more than 85%. It is not suitable for inflammable, explosive and
corrosive gas filled working environment.
Working principle of single beam suspension crane:
The hoisting mechanism of single beam suspension crane includes
brake, motor, reducer, drum and pulley block. The motor drives the
drum to rotate through the reducer, so that the wire rope can be
wound on the drum or put down from the drum to lift the heavy
objects. The trolley frame is a frame supporting and installing the
lifting mechanism and trolley running mechanism, which is usually a
welded structure. The driving modes of the operating mechanism of
single beam suspension crane are divided into two categories: one
is centralized driving, that is, driving the driving wheels on both
sides with a long drive shaft driven by an electric motor; The
other type is separately driven, that is, the driving wheels on
both sides are driven by a motor. Medium and small bridge cranes
mostly adopt the "three in one" driving mode of combining brake,
reducer and motor. In order to facilitate the installation and
adjustment of ordinary bridge cranes with large lifting capacity,
the driving device often adopts universal coupling.
