Carbon Brush Current Collector

Carbon brush current collector for Overhead Crane can be single pole busbar collector, multi-pole busbar collector, seamless conductor rail collector, copperhead conductor rail collector, etc. Its performance, quality, material and the structural components of the material will directly affect the safe operation quality of the whole system equipment. Therefore, the current collector is one of the most important component of the entire conductor rail system. For your different requirements on current, busbar type or installation, we always offer you the right current collector and solutions.
Carbon brush current collector



The carbon brush current collector is composed of carbon brush, stainless metal part and wear resistant plastic part. Spring can make the carbon brush maintain uniform contact. There is a traction arm for each group collector. The double collector system can be used for guiding device or higher current device.



The jointless conductor rail current collector is one of the main devices for picking up electric energy from the collecting side of the conductor system, and the electric energy is directly transmitted to the electric appliance through the sliding contact between the collecting brush and the guide rail, thereby realizing mobile power supply of cranes.



The current collector consists of a mechanical structure tension device and a collector brush that directly contacts the guide rail. The tension device of the mechanical structure determines the sliding contact pressure of the collector brush and the guide rail and the stability of the mechanism. The brush is the conductor of the sliding contact of the guide rail to pick up the electric energy.

Crane Motors / Overhead Crane, Gantry Crane Motors

The motors for cranes are of various famous brands from China and other countries. For your different needs, we provide different option motors brands such as Jiamusi, Jiangxi Special Motors, Siemens, ABB, SEW, etc. We suggest the right brand motors and models according to the cranes you have. Such as ZDS Motor for MD hoist and ZDY motor for electric hoists.
motors for cranes




ZDS Motor:
1. Application scope: MD Hoist
2. ZDS double speed motor cluster is a composite motor which is combined by a low speed drive device between two awl rotor three-phase asynchronous motors.
3. The high-power one is the main motor, and the low-power one is the auxiliary motor. That makes ZDS has two mode of speed: high and low.
4. ZDS is a horizontal type motor, its seat is without foot, and it utilizes cone brake.
5. It's able to start frequently.



ZDY Motor:
1. Application scope: Electric hoists
2. Conical rotor three-phase asynchronous motor.
3. Utilizing automatic brake device.
4. Applies to trolley traveling with electric hoist and crane traveling mechanism.
5. Applies to the drive device that needs small starting torque and smooth brake.
6. It's self-cooled type, and its front cover connects flange.
7. Stator: good moisture-proof performance and thermal stability, and its insulation class reaches B class.
8. Rotor: Running smoothly, small vibration.

Crane Reducers for overhead crane, gantry crane, trolley hoist

1. Application scope: Electric hoist traveling mechanism, gearbox reducers for crane.

2. Widely used in transmission equipment of mining, metallurgy, chemical industry, building material and light industry, etc.

3. The crane reducer should meet the mechanical strength needs when it's used in cranes.

4. Crane reducer mainly used in mechanism of lifting, traveling, rotating and amplitude.

5. The needs of suspension-suit-type gear reducer which is installed in traveling mechanism are small volume, light weight and compact structure; and its output end should be Internal spline which is directly installed in wheel shaft, input end should pass through a coupling and be connected with brake motor by flange; and its top should have holes for pin shaft and buffer device to fix on frame.

6. Crane motor and converter-speed-regulating motor for metallurgy are squirrel-cage rotor motor. Squirrel-cage rotor motor could meet the needs of different working conditions, such as frequent starting, braking, overload, reversing, over speed, collision and vibrating. And it also could meet the need of working under invert control, to realize soft start and four-quadrant operation.

Wire Rope Reel or Drum for overhead crane and gantry crane

1. Wire Rope Reel/Drum Application: Crane accessories for reeling wire rope as a winch or electric hoist.

2. Drum units is constituted by drum, shaft, gearwheel, hub, bearing body and bearing.

3. The material of wire rope drum is usually no less than HT20-40 cast iron, ZG25,ZG35 or Q235B, Q345B welding steel plate is also able to be the material for special needs.

4. Wire rope drum units applies to the large tonnage crane machinery which needs high-performance.
Wire Rope Reel/Drum



For Safety

1. The surface of the single-layer winding drum is cut with a spiral groove with an arc-shaped section to increase the contact area between the wire rope and the drum body, and to fix the winding position of the wire rope on the drum to avoid the influence of adjacent wire ropes rubbing against each other.



2. The surface of the drum body of the multi-layer winding drum is usually a smooth surface without spiral grooves, and there are flanges at both ends of the drum body to prevent the wire rope from slipping out. The disadvantage is that the wire ropes are closely arranged, and the layers are stacked and rubbed against each other, which has a great impact on the life of the wire rope. Among the structural dimensions of the reel, the key dimension that affects the life of the wire rope is the calculated diameter of the reel.



3. In order to ensure the reliable fixation of the wire rope tail and reduce the stress on the pressure plate or wedge, when the pick-up device is lowered to the lower limit position, in addition to the fixed loop of the wire rope, 1.5 to 3 safety loops should be reserved on the reel. Known as the load-relief ring, this has been taken into account in the design of the reel. In use, the more loops of the wire rope tail are retained, the smaller the force on the pressure plate or wedge of the rope tail, and the safer it is. If the lower limit position of the pick-up device is too low and the remaining number of wire ropes on the drum is less than the designed number of safe loops, the force on the tail of the wire rope will exceed the pressing force of the pressure plate or wedge, resulting in the wire rope was pulled off and the heavy object fell.
