Hoist features

Advantages wire rope hoist for small length dimensions, the motor is mounted inside the hoist drum.
Compact metallurgical hoist crane structure, the motor axis is perpendicular to the axis of the hoist drum using a worm gear. Its disadvantages are: the length of large size, large size width aspect, clumsy structure, the low mechanical efficiency, processing is difficult and the like. . Hydraulic system for dual control, the overflow valve, magnetic contact pressure gauges can be precisely controlled. Electrical control department uses a low voltage control, increasing the safety of the disposal system, has no manufacturers of this type of construction product.
Structure and features: The machine uses an electromechanical design, changing different molds, you can suppress the different specifications of wire rope, domination simple, safe. Its main drawback is the motor cooling premise poor, poor groups, inspection, equipment, easy maintenance motors, power supply unit complex. Electric motor axis parallel to the axis of the drum hoist, wire rope hoist its advantages for small height and length dimensions. The disadvantage of a large width dimension, packet poor, manufacturing and assembly complexity.
Classification and narrative component departments explosion proof electric hoist wire rope hoist are: motor, transmission structure idea, drum and sprocket. The mutual positions of the motor and the spool can be roughly divided into four different types. Suppress rope Rally, beautiful, fast, crimping a rope just a few minutes to complete, greatly reduce the labor intensity, improve work efficiency.
Motor mounted on the outside of the drum hoist, the advantage is for the group is good, high degree of common, easily changing the lifting height, unit testing convenient.
The use of electric hoist, can be very extensive, but can the correct use of the advantages of electric hoist for personnel actions may be few and far between, and I am here to suggest that you need to better understand the characteristics of electric hoist, this knowledge, this is more of Hoist use better.

What is the installation of electric chain hoist needs attention?

A: First, install the chain hoist chain need to install the box;

Second, connect the power cord
   When connecting the power cord, must be cut off in advance. Meanwhile ground should be well grounded, otherwise the operator when touching any part of the hoist or chain, are likely to feel a shock feeling.

Third, lubrication chain hoist load chain
   Chain lubrication degree is an important factor in the life of the load chain impact. Timely and effective lubrication of the effective life of the load chain, in order to ensure the chain.
Fourth, check the chain arrangement
   For multi-line chains, electric chain hoist, make sure not to be flipped under hook rack. If you flip to restore it to a normal state, to ensure that the chain of welding mouth arranged in rows. Do not twist the electric wire rope hoist manufacturers suspended load.

Finally, check the operating voltage
   Because when the chain hoist factory, is based on user-specified voltage or high voltage equipment (only dual voltage terms), such as 230 / 460V, need to check the wiring and make sure the power supply voltage requirements are met. If not, refer to the manual must be corrected in order to meet the requirements of the operating voltage.

    Tips: Installing electric chain hoist, if operated at improper voltage electric chain hoist might cause serious damage. To prevent this situation, it is necessary to meet the requirements needed to ensure that the power supply wiring.

Electric chain hoist use? Features?

A: for low-speed material handling aspects of a small stroke, equipment installation, mining and engineering construction, cheap, safe and reliable, bring convenience to your work.

It retains the chain hoists lightweight and convenient features, and improved manual chain hoists, lifting speed and slow enough that it combines the advantages of explosion proof hoists  and chain hoists in one, using the disc brake motor powered, planetary gear decelerate, with a compact, small size, light weight, high efficiency, easy to use, reliable braking, easy maintenance features.

What is the difference between chain hoist and wire rope hoist is?

A: The chain is a chain hoist, wire rope electric hoist is a rope, chain hoist the quality of my company guaranteed low prices.
CD1, MD1 type explosion proof electric hoist is a small light lifting equipment, with a compact, light weight, small size, parts versatility, easy operation.

General Electric Hoist

Electric hoist is a small light lifting equipment, installed in the top of the crane, with a small size, light weight, simple operation, easy to use features for industrial and mining enterprises, storage terminals and other places. Weight is generally from 0.1 to 80 tons, lifting height of 3 to 30 meters. By the motor, transmission and rolls or sprockets, divided into wire rope hoist and electric chain hoist two. explosion proof hoists into two kinds of imported and domestic; wire rope hoist points CD1 type (single speed upgrade), MD1 type (double speed upgrade); mini electric hoist, hoist, hoist multi-functional. Starting weight: 0.25t-60tELK electric wire rope hoists crane _ _ ELK chain hoist _ _ crane lifting height: 3m-30m working level: M3 running speed: 20 (30) m / min Lifting speed: 8m / min

Problem hoist rails might encounter

The vast majority of metallurgical hoist crane is installed on a handful of fixed rail. Before installing hoist rail beam must first understand the type, length, with or without seams, with or without bumper and grounded. Only rail model and implement a mechanism to be able to adjust to run the installation space. If the rail is too long and way too weld the best in the "front rail lifting" the welds polished to avoid future rail and hoists are installed after the completion of the sports car appeared blocked walking "slip" or even "bounce" that could not explosion proof hoist Road, rail joints smoothly beyond the situation. Treatment could have increased the difficulty of solving the problem on the ground have had to deal with starting the fire and aerial job ticket, fill paint corrosion occurs only cause duplicate scaffolding erection problems also added a safety hazard. Road, rail Although it is not our work, but I think we all know that "interdependent", "gates of fire adverse impacts to fish," the truth. This requires that we implement on-site technicians often run rail installation progress and keep good communication with technicians brothers rail mounted unit is responsible for the post-commissioning, acceptance of work to do preliminary groundwork. Otherwise, when the relevant technical personnel responsible for the installation of rail have been removed from this work truly become "historical issues" after dealing with them is extremely difficult.
Besides bumper. In many cases the ends of the bumper rail away from walls and other equipment or buildings too close to explosion proof electric hoist the body longer and therefore they are easily accessible in the welding bumper level best to hoist the end face of the front wheel from the car to walk the distance as bumper welding actual position basis. Often a lot of cars stand in front of the factory rail welding is completed, but the actual site conditions must prevail before lifting. To avoid the trouble to produce bumper complete transformation of the ground and do the best are embalmed. Some bumper design a buffer or cushion rubber block of wood which requires that we must be optimistic about the drawings are often not so fine for content on our own installation crew received the drawings, it is necessary to consult other departments on rail details condition. In the transfer of rail when we must implement the above, or not receive.
