Carbon Brush Current Collector / Weihua Crane

 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. 

 

 

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.

 

Carbon brush current collector

 

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.

Wire Rope / Weihua Crane

 Wire rope is applicable for Overhead Crane, Gantry Crane, container cranes, shore crane, crawler cranes, offshore fixed cranes, pile drivers, ship unloader cranes, etc. Crane wire rope is constituted by steel wire, rope core and grease. 

 

Wire rope

 

Features of Crane Steel Wire Rope:

1. Application: Lifting, towing, straining and load bearing of electric hoist or winch.

2. High strength with more than 1770Mpa tensile strength, large capacity, strong overload capacity, good elasticity, impact resistance and light self-weight.

3. Crane Wire Rope has good flexibility, stable operation and low noise during high-speed movement. Because it needs to be wound on multiple layers on the reel, it should have good bending fatigue performance.

4. It is reliable in work and will not break suddenly. This is a necessary condition for lifting and safe work.

 

 

 

According to the above features, we generally recommend that customers wire-contact wire ropes, such as 6*36SW. In special occasions, we recommend customers 8*36SW or compacted wire ropes.

Crane Rails / Weihua Crane

 Crane rails are the main body of crane tracks. Crane rails provide a continuous, smooth and low-resistance rolling surface for the crane wheels. It is employed to guide the wheels of the crane, bear the pressure of the wheel, and transmit it to the sleeper and ground. Weihua provide various models such as QU70, QU80, QU120, etc. for the different crane and special conditions.

 

Crane rails

 

Features of Crane Rails:

1. Application: Rails/tracks for Overhead Crane, Gantry Crane, RMG, Project Crane, etc.

2. Pulling wire rope to detect the linearity of rails. Pulling a diameter 0.5mm wire rope between two ends stop lever, and using a plumb bob to detect point by point, and the interval should be 2 meter.

3. The crane rail joints could be cut into straight joint or 45°oblique joint.

4. P shape rail is the most commonly used.

Crane Coupling / Weihua Crane

 Coupling is the most commonly seen connecting components in shafting transmission of Overhead Crane and Gantry Crane. We made customized crane coupling with different size, different materials, and for different cranes.

 

Coupling

 

Pairs of Gear Coupling

1. Application scope:  Connecting different mechanism

2. Coupling is constituted by two parts. One connects the drive shaft, another connects the driven shaft.

3. Coupling is the most used connecting components in shafting transmission of machinery.

4. There are two types: Fixed coupling and movable coupling.

5. In high-speed and heavy-load power transmission, some couplings could buffer and absorb shock to improve the dynamic performance of shafting.
