HC/HM Electric Wire Rope Hoists are light and small-sized lifting equipments for lifting small and heavy cargoes, with more reasonable and tight structure, more convenient assembly, their property is more superior than normal electric wire rope hoists. HC/HM electric wire rope hoists have excellent control characteristics with minimal setting force required, both double hook use and single use are ok. 

The lifting capacity of the electric wire rope hoists ranges from 16ton to 100ton, the lifting height from 9m to 30m, and the control models are pendant pushbuttons or wireless remote control. They can be suspended on I- beam track for straight or curve traversing (of Single-girder Cranes) or mounted on a fixed frame. They can also be used together with Electric Hoist Double girder, gantry crane and slewing cranes to hoist different items and so on. What’ s more, Model HM electric wire rope hoists provides two speeds: normal speed and low speed. At a low speed, it can do precise loading and unloading, mounding of sand box, maintenance of machine tools.While Model HC has only one normal speed, which can satisfy normal application and deal with tough environments. Thus, model HM’s applications are more widely than Model HC. 

Besides, altitude less than 1000m, Lifting height is 6m-30m, working duty is A3, ambient temperature is -20~40°C, and air relative humidity should not be more than 85%(+25℃), with non- corrosive gases, high temperatures should not be lifted or toxic, flammable and explosive materials. 

There are normally 4 Types of Electric Wire Rope Hoists as below, and HC, HM Serise belong to the first 2: 

Fixed Position electric wire rope hoists: Manufactured for basic installations where the hoist will be in a static position, most can be upgraded to feature a trolley at a later date, also named Foot mounted fixed position hoist units (supported or suspended). Monorail Wire Rope Hoists: Designed to travel horizontally along a beam with a standard headroom configuration, also named Standard headroom monorail hoist 

Low Headroom electric wire rope hoists: Designed to gain the maximum hook path in applications where the headroom is low or where hoist dimensions need to be kept 'Low Profile' bringing the hook right up to the beam, also called Low headroom monorail hoist 

Twin Beam (Crab Units Including special gauges) Electric Wire Rope Hoists: suitable for dual girder Overhead Cranes where the hoist sits on top of the girders instead of running along the bottom flange like the other variations. This also allows maximum hook path and higher capacities 

HC/HM electric wire rope hoists are widely applicable for lifting heavy goods, stacking materials, hoisting prefabricates and cement pipes, and installing equipment in machinery factories, mines, harbors, docks, ports, warehouses, logistic, good yards, construction industries, hospitals, cargo storage areas and repairing shops, food products factories, wharfs, to hoist materials directly, essential in raising working efficiency and improving working conditions.
                                                 

1. Lifting motor 

          Lifting motor adopt the best quality motors with bigger torque so it can be adapted to moving frequently,the Maximum torque is 2.4-3 times than the rated torque. Motors are equipped which has safety limiter in both up and down directions. They are produced by China top brand motor from Nanjing.
          Lifting motor uses tapered rotor motor with braking (Conic rotor brake motor/ tapered rotor conical motors), with strong staring torque to adapt frequent direct staring in the intermittent work, to brake asynchronous motor and does not need extra arrester, The motor’load duration factor is 25%, the motor uses B frade and F grade insulation and its grade of protection isIP44/IP54.High efficient energy-saving motor, asbestos free brake systems are available. HC electric wire rope hoists use ZD type single speed motor and HM electric wire rope hoists use ZD double speed motor. The ratio of ZDs type motor’s constant speed and slow speed is 10:1.            

2. Speed reducer 

           The electric wire rope hoists use helical gear three stage reducer (Third-class dead axel helical gear transmission structure is adopted), Gear and shaft are made by alloy steel and high carbon steel and through proper heat treatment to ensure its reliability, high mechanical efficiency and service life.                             Case and case cover with precise assembly and good seal are made of quality cast iron, the reducer is independent, so it’s easy to load and unload it. Box body and cover is made of cast iron to ensure hoist's good damping performance and reliable sealing. 

3. Rope drum 

           Rope Drum is made of cast iron or seamless steel tube, using/with the help of spline transferring power. its shell is welded with steel plate. The drum device is the central part of hoists Grooved drum, seamless pipe of adequate length to be wounded in one layer and to provide proper support for the rope to minimize abrasive wear is provided.Drum Shaft resolves on Ball Bearings for ensuring smooth running. Rope drum is the central heart of a electric wire rope hoist. The upper side is linked with traveling mechanism through equalizing beam. Both ends are connected with lifting brake and motor respectively. The lower side works together with hook through wire rope. Up front of the cover, limiting stopper guide-rod and heavy punch stop block are installed.

5. Limit switch 

           Limit switch devices are fitted at both top & bottom ends, switch off power automatically to prevent load chain from running out. 

6. Safety brake 

           The dual-disk electromagnetic brake features automatic brake in the event of a power failure. As best of free brake linings designed for approx.1million braking operations make for long maintenance intervals.Pushbutton swith is rain proof plastic for severe impact and corrosive atmosphere resistance and mechanically interlocked. 

7. Traveling mechanism 

           Traveling mechanism is made of electric crab, traveling motor, traveling reducer, driven crab and so on. Main engine hangs under the traveling mechanism moving reciprocally. The normal traveling speed is 20 or 30m/min. If the lift capacity is 1~5t and the lift height is or more than 12m, another driven crab is installed. 

8. Electric device 

             The electric device of HC electric wire rope hoists consists of electric control box, button switch,Limiting stopper,connecting wires and so on. The normal operating voltage of button switch is 380V or 36V.Pressing the correct button can control the hoist through controlling on and off of the relay in the control box, according to the direction symbols on the button switch. The control has wired type and wireless type (or cord operation and cordless remote control),It can be choosed by your requirement, Its features are with waterproof protection, light and durable, In addition, the control box has device with up an down stroke protection of break off limiter and can cut off main circuit in an emergency, which ensures safe operation of electric hoist, Electric elements are of long servicelife and operational safety. 

9. Steel wire rope 

           It uses GB1102-74(6*37+1) hoist steel wire rope which is durable in use, Improved plow steel pre-formed cable for maximum strength and life. Hoisting ropes comply with the exporting standards. The leading rope taken by the drum does not slip sideways when slack. The factor of safety, on the nominal breaking strength of the rope is six. 

10. Lifting hook 

           Lifting hook is forged with specialized steel, heat treated and fracture resistant, In case of dangerous overloading or abuse, the hook does not fracture but will slowly yield. In the use of trust ball bearing, lifting hook is linked with shekel through hook beam making lifting hook go slick. If lifting capacity is five ton or less than five ton, slide wheel is single. If lift capacity is ten ton or more than ten ton, slide wheels are double.The Hook Block is tested to 150% of full load before assembly, with 360 degree rotation and high bearing strength.
