Including upper and lower hook , load chain , push button , chain spring , chain bag etc .
3. Core components materials
Hoist body housing : High strength Cast Aluminum Alloy , Die- casting molding .
Hoist motor : self-made motor with high quality cooper wire winding , using die-casting Aluminum motor housing , be good for heat dissipation .
Gears : High strength Alloy steel and heat treated , with high precision .
Chain Wheel : Be made of ductile , wearable and lubrication .
Casting Parts : HT, QT serials material .
Steel Plate Parts : Q345B .
Load Chain : High strength FEC G80 Alloy steel chain , or Chinese Super heat treated Alloy Steel .
Upper and lower hooks : Hot forged and heat treated , DG20Mn .
Chain container : Canvas or steel chain container , depends on different lifting height .
4. Electric chain hoist advantages :
Customizable – chain hoist can be customized according to different requirement from different customers , related to the site working situation . Different capacity , lifting height , power voltage , service environment situation , speed , even different color favorite . OEM service is also available .
High production efficiency – By lifting heavy weight , electric hoist reduce the intensity of the workers' work, and lowering the risk of injury . Meanwhile, increase the production efficiency . High cost -performance - compared with wire rope hoist , generally , electric chain hoist is much cheaper , but can meet the same requirement of lifting .
Portable – electric chain hoist can be easily transported from one site to another . Indoor/outdoor use – Hoisting equipment can be used with equipment both inside a facility and outside, on the dock or in the yard .
Lower maintenance cost –Due to the smaller compact structure , light and portable ,electric chain hoist maintenance cost is lower than those large size lifting equipment .
Safety – With high quality , being operated by well trained operators in specified area , electric hoist is a safe lifting device .
Electric chain hoists are usually matching used together with bridge crane (overhead crane ) workstation crane , monorail crane , mobile gantry crane and different type jib cranes . They are widely used in different industries , such as manufacturing factory , warehouse material handling , logistics transportation , railway , building construction , port , mining and so on , used for lifting , loading or unloading heavy weight . The electric hoist can be controlled by operator with push button on the ground , can be also controlled by wireless radio remote .
There are different model of electric hoist :
Hook fixed type - with upper hook suspension on one position , just lifting up and down functions .
Hoist with monorail beam trolley - electric beam trolley / hand push trolley / chain pulley geared trolley , acting the functions of lifting up / down , traveling East / West .
