Crane Brake / Weihua Crane

Crane brake is an important parts for Overhead Crane or Gantry Crane, which can decelerate and stop the running of a crane.

 

Crane brake

1. Application: Crane brake is for the moving parts deceleration.

2. There are 2 types: friction brake and non-friction brake.

3. Crane brake is mainly constituted by brake pad, brake arm, brake wheel and brake releaser.

4. To reduce the braking torque and the size of brake frame, the brake is usually installed on the high-speed shaft. To meet the needs of high safety for large machinery, like mine hoist and elevator, the brake should be installed on the low-speed shaft which next to the working parts the large machinery.

Crane Reducers / Weihua Crane

1. Application scope: Electric hoist traveling mechanism, 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 / Weihua 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. Drum units applies to the large tonnage crane machinery which needs high-performance.

Chain Bucket Car Unloader / Weihua Group

As a kind of unloading and stacking unloader equipment which is used for the bulk materials on the railway, the chain bucket car unloader is mainly applied to the car unloading in the thermal power plants, factories and mines and port railway lines. The chain bucket car unloader shall stretch across the railway wagon to apply chain bucket to take the coal and adopt the tape conveyor to transmit the materials. Therefore, it is unnecessary to open the car door with high working efficiency and favorable economic benefits; It can unload coals beyond the truck for several meters.

chain bucket car unloader

It is good for continuous unloading; Due to the stable traveling speed and transport capacity, it is convenient to cooperate with other machineries to accomplish the stacking task just one time. The chain bucket car unloader is composed of engine body, bucket hoisting device, winch, tape conveyor, traveling mechanism, etc.

Cantilever Bucket-wheel Stacker Reclaimer / Weihua Group

As a kind of high-efficient, continuous and large-scale handling equipment which is suitable for the bulk materials, the cantilever bucket-wheel stacker reclaimer is mainly used for the handling of coal and ore storage yards in the electricity, metallurgy, coal, building materials, chemical and other industries.

cantilever bucket-wheel stacker reclaimer

Our company's arm-type bucket-wheel stacker reclaimer has the arm range and stacking capacity range of 20-60m and 100-10000t/h respectively. The above-mentioned equipment is widely applied to the strip materials yard.

Performance Features:

1. The cantilever bucket-wheel stacker reclaimer can integrate hoisting, transportation, excavation and other functions with high efficient. Considering that it can combine the excavation mechanism with the transportation devices, these two mechanism can make continuous operation, therein, the former mechanism shall take charge of reclaiming and the later mechanism is used for transportation.

2. Low energy consumption The materials are transported by the belt conveyor which has small resistance. Meanwhile, the slewing mechanism applies the rolling bearing to reduce the power consumption.

3. Long service life. Due to the small impact force during reclaiming, small abrasion of spare parts and the wear-resistant materials which are applied by the bucket tooth, the machine can prolong its service life.

4. Easy operation Considering that PLC is applied to control the machine, its working process has realized the semi-automation and automation. The cantilever slewing applies 1/cos frequency control to make the machine in the high-efficient state.

5. It applies the advanced design method. Such as, the computer aided design, three-dimensional design and the optimized design of steel structure can absorb the advanced technology from foreign countries, as a result, the machine can be designed by the advanced and reasonable technology due to the stacker reclaimer designing & manufacturing experience and the continuous summary & enhancement, therefore, the equipment can be put into practice reliably.

6. The equipment is guaranteed by the advanced production equipment and technology means. Such as, the steel pretreatment production line can enhance the products quality and wear-resistant capacity, however, the large-scale milling & boring machine has improved the processing quality of large parts. The large structural parts shall be integrally preassembled in the factory, the driving parts shall accept the trail run in the factory, and the slewing parts shall be prepared by the mould.

Stacking and reclaiming:

Stacking: coal → ground belt conveyor → auxiliary tail car → main tail car → main tail car head hopper → boom belt conveyor guide trough → boom belt conveyor → coal storage yard.

Reclaiming: coal→ bucket wheel mechanism→ boom belt conveyor→ center drop hopper→ ground belt conveyor.
