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.
