Lift hoist should be defined as

Lift hoist should be defined as: Lift hoist up and down in the vertical channel to carry people or cargo lifting platform or lifting machinery or apparatus semi-closed platforms.cheap wire rope hoist By the platform as a whole as well as equipment, motors, cables, and other auxiliary equipment operated by the composition.
lift hoist Introduction.
Lift hoist into the following mobile, fixed, wall-mounted, towed, self-propelled, vehicle-mounted, retractable total of seven categories.During rotation operation of the lift platform must be played before the next boom lifting height rotating, slowly rotating,manual chain pulley block and cut arm and a platform from a variety of equipment meets safety requirements.

Liftech Equipment Wire rope winch accidents


1.Wire rope winch fixed and firm, not solid ground anchor set,cheap wire rope hoist leading to hoist shift and overturning.
No guards or protective devices to prevent slippage of the rope unreasonable, unreliable, resulting from the hoist rope on a 2 roll.
3 is not the end of the rope does not meet the requirements of the fixed or stationary, so that the rope off.
4 winch brake failure,lifting clamp unable to locate.
5 rope drum axle shaft end position is not accurate cause fatigue fracture.

Application of the technology in electric hoist hook

electric hoist trolley hook is a hook hoisting machinery in the most common. By electric hoistand pulley block part is hung on the hoisting mechanism of the wire rope or chain.According to the shape is divided into single and double hook hook, according to the manufacturing method for forging and laminated. three phase electric hoist hook is made of gold, steel, heat treated, chain, annealing, surface anti-corrosiontreatment produced, we understand in detail the application of the technology in electric hoist hook.
Electric hoist single hook has the advantages of simple manufacture, convenient use,but the stress condition is not good, mostly in the weight for the workplace 80 tons; big lifting weight often use force symmetrical double hook. Laminated hook which is composed of a plurality of cutting steel plate riveted together, the hook will not damage the cracks of individual plates, security is better, but the large self weight,mostly used in large capacity or the lifting of the molten steel ladle crane. The hook is often affected by the impact during the operation, the good toughness of high quality carbon steel manufacturing.
Mainly because of cheap wire rope hoist  in the use process, there are rarely have an overload situation. In this case, there will be deformation of the hook. And hook groupgeneral in the hanging point, is not easy to detect, if there are serious consequences.The hook is very easy to see the visual hook changes, minimize risk hook deformationalso continue to work. So the artificial let tensile strength hook group is different, it is necessary to.

Single rope winding lifting equipment

An earlier onset , it is reliable, simple structure, but only for shallow and medium depth of the mine , and the terminal load is not too large . For deep wells and the terminal load is large, a large rope and hoist upgrade roll diameter , resulting in a hoist equipmentlarge volume , gravity soared, making the hoisting rope and hoist the manufacture , transport and use on both inconvenience. Thus , to a liftech cheap wire rope hoistcertain extent, limit the single rope winding hoist used in deep well conditions. Friction appears to enhance its development machine , to a certain extent, solve the single rope winding hoist that appear under the condition of deep problems. However , things are always divided into two . Generally used to enhance the friction tail rope balanced tension at both ends to reduce the error and improve reliability. Thus , the container connection with hoisting rope rope section , the static stress changes with position changes of the container . When the container is located in the unloading liftech hoist and trolleyposition the wellhead , the gravity of the entire container and the end of the gravity are acting on the rope of the section ; arrival when the container bottom before loading position to withstand only the gravity of the section of the container. In other words, the entire upgrade process, with the hoisting rope section of the vessel to bear in connection with an amplitude of . static stress changes σj = qH / S0 of (q is the tail rope per meter gravity , N / m H as lifting height , m S0 to enhance the cross sectional area of ​​the wire rope , cm2).
