Wire Rope Electric Hoist

CD or MD model monorail Wire Rope Electric Hoist is a kind of light-duty lifting equipment with advantages of tight structure, light weight, small volume, wide common use and convenient operation etc.If reducers with hard gear surface are applied, it will have long life and high mechanical efficiency. Conic rotor brake motors are equipped which has safety limiter in both up and down directions.

CD model electric hoist has one lifting speed.

MD model electric hoist has normal lifting speed and slow lifting speed which make it lift steadily and accurately.
CD or MD model electric hoist can be widely used to hoist heavy objects, or installed on the straight or curve I-section steel beam of single beam cranes. They can also be used together with Electric Hoist Double beam gantry cranes and jib cranes. All the above has made the electric hoists common in industrial and ore enterprises, railway, wharfs and warehouses.
The standard capacity of this type electric hoist: 0.5T, 1T, 2T, 3T, 5T, 10T, 16T, 20T.
Lifting height: 6m, 9m, 12m, 18m, 24m, 30m, and Max. 100m.

Boat Lifting Gantry Crane-nucleon crane group

Ruber Tyre Mobile Boat Lifting Gantry Crane

 Detail specification 

1.Electro-hydraulic transmission system is adopted in hoisting and traveling parts and features small volumn, light weight, compact structure, smooth running, quick response, small inertia, easy operation and automation. The crane is able to high-speed start, brake and turn. ]

2. Multipoint hoisting disperses forces acting on the hull without strongly pressuring. Movable hoisting points and dynamic balance are suitable for boats of different types and can automatically adjust the deflection angle for adaption. 

3. Radar anti-collision method is safe and effective.

 4. Adoption of load sensitive control technology enables the crane to produce output as actual demand to prevent energy wasts.

 5. Soft but sturdy hoisting belts make no damage on hulls surface.

The Overhead Crane Purpose and Feature-nucleon crane group

The Overhead Crane Purpose and Feature-nucleon crane group

The Overhead Crane Purpose and Feature

Overhead Crane is mainly used for loading and unloading materials and handling of materials, is an important modern production equipment. Using of lifting and transport machinery can reduce labor intensity, reduce loading and unloading costs, reduce the damage of goods and improve labor productivity, production process mechanization and automation indispensable machinery and equipment. It is widely used in factories, mines, ports, railway stations, construction sites, power plants and other production areas. Hoisting machinery is the intermittent, repetitive work, lifting hook or other spreader lifting, lowering, or lifting and transporting heavy machinery and equipment. Its working characteristics are cyclical. In each working cycle, its main body for a forward and reverse movement, each cycle, including the loading and unloading of items, moving objects and the work of the trip after unloading empty hook return, between the two before and after loading There is a brief stop including assist preparation time.

Comprehensive work characteristics of lifting appliances, from the perspective of security technology can be summarized as follows:

(1) Electric Hoist usually has a large structure and more complex institutions, to complete a lifting movement, one or more horizontal movement. Operation process, often several different directions of movement at the same time operation, technical difficulty.

(2) the lifting of a variety of heavy loads, the load is changing. Some heavy objects weighing hundreds of tons or even thousands of tons, and some objects up to tens of meters, the shape is very irregular, so that the lifting process is complex and dangerous.

(3) most of the lifting machinery, need to run in a larger range, and some to install rails and wheels (such as tower Overhead Cranes, bridge Overhead Cranes, etc.), and some to install tires or track walking on the ground (Such as passenger, cargo aerial ropeway), a larger space, once the impact of the area caused by the accident is also larger.

(4) Some hoisting machines, need to direct transport personnel in the rails, platforms or wire rope to do lifting movements (such as elevators, lifting platform, etc.), its reliability directly affect personal safety.

(5) Much more exposed, active parts, and often direct contact with the lifting workers (such as hooks, wire rope, etc.), potentially many risk factors.

(6) operating environment is complex. From the large iron and steel joint ventures, to modern ports, construction sites have hoisting machinery in operation; often encounter high temperature, high pressure, strong magnetic and other risk factors, the formation of a threat to equipment and operations personnel.

(7) operations often require people to cooperate, to conduct an operation, command, strapping, driving and other operating personnel with skilled, action coordination, take care of each other, the operating personnel should have the ability to deal with emergency situations on the spot. A number of workers working closely with each other, there is a greater difficulty.

It is precisely because of the above-mentioned factors, the Overhead Crane injury accidents are more, so when using the lifting equipment must be strictly good safety clearance, as much as possible to reduce the accident. Enterprises should regularly check the lifting equipment to eliminate security risks.

is a jam phenomenon,when necessary change the contactor.

First check electric hoist power fuse whether burn out.If broken on one side, electric hoist electric
thought single-phase starting, the starting torque is zero, electric thought can’t scroll, should be
changed enough fuse.
If the electric hoist ， first removing load, such as electric performance is normal starting, explain
reducer, such as the thought structure has fault, should check at once,Eliminate malfunction.

Stator winding and short circuit, grounding or open circuit, winding grounding when in the lead on the
floor, should open the junction box to check
