In the cold winter, the electric hoist operation is very inconvenient,the construction is more difficult especially after the snow,  1 ton electric chain hoists  are often unable to work because of the weather factors, how to deal with it? In general, the electric hoist prone to failure in the motor in winter, because the weather is too cold, easily lead to electric hoist motor can not boot, in this case, do not unload the electric hoist rashly, the basic reason lies in the frozen brake ring. If forcibly boot, easily burn out the motor. So when the electric hoist is unable to boot in winter, must not act rashly, the best solution is to open the motor cover, to pry the motor with a crowbar, which can make it rotate freely, then power up the  electrical chain block , it can work normally.

Lever hoist  is a clamp body which through manually pulling the handle, with the lever principle to obtain the linear traction which matched load, acting on the load in the movement, to drive the load operation.  Manual lever chain hoist  has the advantages of compact structure, light weight, small size, easy to carry, labor saving, safe and reliable, long service life, small hand pulling force, small wear on the wire rope and so on. Lever hoist can be used to lift, drag, drop and calibrate. If set the special device, not only can be used for non linear traction operation, but also can easily select the appropriate operating position, or in small tonnage equipment multiplied the load capacity, for the large tonnage load can be used in parallel operation of several machines.

Chain lever hoist  as the upgraded version of fixed pulley , has all the advantages of the fixed pulley, and the combination of reverse non-return brake deceleration device and chain pulley, symmetrical arrangement of two gear rotating, which is simple, durable and high efficiency. Manual lever chain hoist  by rotate by pulling drag chain and chain wheel, the friction plate ratchet wheel and the brake seat are pressed into one to rotate together, the tooth long axis turn the piece gear, gear shaft and short splined gear. Then, the chain wheel arranged in the splined gear drive the chain, thus smoothly lifting the weights.The friction ratchet one-way brake, can automatically brake under load. Under the action of the spring, the pawl is engaged with the ratchet wheel, brake safety work.

In process of electric hoist running in I-steel is prone to problems which is the object is swing, so how to solve this problem, let WOKAITE which is a  china electric chain hoist manufacturer  to answer your questions: The running distance of  chain electric hoist  on the the end beam should not be too long, or install fixed device in the middle of the end beam. Do not lift the load on the side of the beam in operation. When the lifting load is swing might hurt people and objects even fall to the ground, result in death or serious injury and other accidents. If the load is swing, the more powerful the swing, the more difficult the operation of the trolley, accompanied by danger. Don’t sway the load in principle. Therefore, please observe the following operations. 1.Don’t pull hanging obliquely. 2.Move slowly when it moves laterally 3.Do not lift the load sharply. When start and stop the transverse movement of  electric chain hoist , even if obey the above operation rules, lifting

Nowadays,  single girder overhead EOT crane  is widely used in all aspects of the industry, and the corresponding is that many enterprises are lack of single beam crane operator. Before use The use of  single beam crane  is not a simple matter, should be completed on the inspection of operating personnel before start-up, including whether the crane components are in good condition, the wire rope can continue to use, and the crane hook is intact. In addition, before running the crane, the operator should also be recognized that there is no one above the table, in order to prevent accidents. In use In the use of the  EOT crane  also notes a lot, firstly every time before formal lifting, the operator should try the performance of crane is suitable to lifting, should lift heavy object up half meters high, ensure there’s no problem and then continue to use. After use After using the single beam crane, the crane operator should lift the hoist in a certain height, then fixed, after fix

Winch and  electric chain hoist  as the most commonly used light lifting machinery, because of their convenient to maintenance and many other advantages is widely used in all aspects of industrial production. There is little difference from the appearance, perhaps can find some difference from the actual use process. We distinguish in detail from the operation mode, lifting height, lifting speed, appearance and other aspects. 1.From the view of operation mode, the electric hoist can shift around, while winch can only use fixed. 2.From the view of speed, the commonly used  electric wire rope hoist  lifting speed for 8M/ minutes, a slow mode winch can reach 10M/ minutes. 3.From the view of lifting height,  electric cable hoist  can usually lift to 6 ~ 12 meters, and the installation of wire rope is not convenient, the installation will bring a series of problems. The lifting height of winch depends on the capacity of the drum, 100 meters in general. 4.From the view of appearance, elec
