MD-type electric hoist

MD-type electricelectric hoist, it has a light weight, simple structure, in the form of a novel, smooth characteristics, when running with a small car, MD electric Electric wire rope hoistcan be made straight and curved reciprocating circular motion in the horizontal direction, which can be in made on the beam overhead track use, but also with other metal structures supporting electric or become subject to manual single-beam, dual beam, cantilever, gantry cranes and stacking etc.

PA mini electric hoist

Mini electric hoist, also known as the civilian electric Electric wire rope hoist. For various occasions, can enhance the cargo of 1000 kg or less, mini electric hoist is particularly applicable to high-rise buildings tenants to lift heavy items from downstairs. Simple structure, easy installation, small size, and with a unidirectional power as a power source. Mini electric hoist in the production design are up to international standards to ensure the safety of the use of motor heat sink made of cast iron structure, improve the service life. Mini electric electric hoist speed can reach 10 m / min, rope length is 12 meters early design (longer can be customized), the hook, the hook specially designed with advanced settings, greatly increasing the mini electric hoist lifting weight mini electric hoist 220V civil power, especially for daily use, industrial production lines, freight logistics and other occasions

Proof electric hoist

Explosion-proof electricElectric wire rope hoist for the occasion containing flammable gas, vapor and air to form an explosive mixture of, with a compact, light weight, small size, large lifting capacity and so on. HBJ series explosion-proof electricelectric hoist for having IIA, IIB, IIC class, temperature class T1 ~ T4 group place flammable gas or vapor and air explosive gas mixture composition.

Electric chain hoist

Electric chain hoist chain is soldered Park as the bearer of the Electric wire rope hoist. Compared with the wire rope hoist, the structure more compact, cheaper. PK-type electric chain hoist, the product has a compact structure, small size, light weight, easy operation, safe and reliable. PK-type electric chain hoist can be installed on floating beams, curved rails and fixed-point lifting heavy objects, especially in the construction of the plant is not suitable for low bridge cranes, beam cranes places, and the choice of wire rope hoists volume the place is too large, PK-type electric chainelectric hoist has its unique advantages. Because of the small size, with a variety of ways according to

installation, in addition to the use of fixed suspension, you can also configure the chain sprocket car, electric car run for in a clean studio, laboratory; you can plant in a single room for the high-precision machine tools, machining center, engine testing and other commissioning lifting workpiece. Configured to run electric car simple structure, light weight, easy handling, permanent installation, can also be used temporarily. Electric chain hoists are widely used in the wharf, construction and modernization of production lines

CD1-type wire rope hoist

CD1 wire rope Electric wire rope hoist is a small light lifting equipment, with a compact, light weight, small size, parts versatility, easy operation. CD1 wire rope hoist is a small light lifting equipment, it can be installed in a single girder crane, bridge crane, the gantry cranes, jib cranes and other cranes, a little change, you can also do hoist, CD1 electric electric hoist lifting normal speed, to meet the requirements of the general situation, and suitable for factories, mines, ports, warehouses, shops and other venues to use.

Double girder crane precautions during the use

Double girder overhead crane is lifting the transport of modern industrial production and production process to achieve brake mechanization and automation of important tools and equipment. Double girder Light duty electric winchs in the indoor and outdoor industrial and mining, iron and steel industry, railways, ports and logistics flow and other departments and establishments have been widely used.
Double girder cranes stop Precautions
1, after the job is completed, the crane open to designated locations: one end of the car to open the cab, hook rises, all the control panel to "zero", cut off the power and wipe clean and keep clean.
2, good operating records and shift work shift. Double girder crane use surface cracks will appear, there are a variety of reasons

1, the load force can not change the direction of the back and forth: double girder crane lifting process, moving back and forth due to heavy attack has changed, especially in the severe load condition, the formation of discontinuity average beam, the beam will attack crack form life began double girder crane lowered.
2, wind can affect double girder electric hoist: When using double beam crane outside after midnight, the wind blowing through the inevitably large wind start, double girder cranes will attack shaking phenomenon, the appearance will attack cracks.

Electric single girder crane girder institutional analysis

Electric single girderelectric hoiststructure has 70 years of history in the form of a single beam of variety, such as: add truss beam, I-beam tube plus, plus a triangular box girder beams, rectangular box girder beam plus more.
These single girder crane girder composite section has many deficiencies, such as the thickness of the beam height is too high, and cover the same web (n-type orange), material utilization is not reasonable, composite section of the welding process and repression increase the cost of production.
In recent years, the domestic electric single girder crane (LDA type 1 to 20 ton electric single girderElectric wire rope hoist http://www.cn-cranes.com/html/danliang/40.html) girder section some new patterns. In this paper, local bending stress flat flange steel plate at the edge of the wing hoist wheel pressure effects arising from analysis.

First was the distribution of local bending stresses measured by simulation, structural analysis and then use the MAS program to compute the finite element model analysis, the maximum stress calculation charts and curves. From the experimental results and finite element analysis results obtained local maximum bending stress flange plate mainly in the loading point and the corresponding free edges and roots.

Electric hoist

There Column, wall-mounted and balanced electric hoist three forms.
① column cantilever Electric wire rope hoist boom can be fixed in a given column around the base of the swing, or cantilever column and turn rigid, support within the base together with respect to the vertical centerline of rotation composed by columns and cantilever cranes. It applies from the weight of small, round or job scope of services sector occasions. General machine tools and other artifacts for chucking and handling. Column cantilever crane use more electric chain hoist as lifting mechanism and operation mechanism, less use of wire rope hoist and chain hoists. Rotation and horizontal movement to use more manual work, only play a greater weight
When using electric.
② wallr electric hoist is fixed to the wall of the cantilever crane or jib cranes can along the wall or on an elevated track running other supporting structure. Wall crane line using the occasion to span large building height larger workshop or warehouse, close to the wall when lifting operations more frequently near the best. Cranes line the walls and above the multi-beam bridge crane or with the use of the service on a wall near a rectangular space, responsible for lifting small light objects, large borne by the beam or bridge crane.

③ balance electric hoist known as balance suspended, it is the use of four-bar linkage principle to make the load and the counterweight constitute a balanced system, you can use a variety of spreader flexible and easily lifting loads in three-dimensional space. Balance electric hoist lightweight and flexible, it is an ideal for lifting small items of lifting equipment, is widely used in factory floor machine loading and unloading, inter-process, automatic line, production line of the workpiece, lifting sand box, parts assembly, and stations, docks, warehouses and other occasions
