Weihua Production Capacity of Crane Trolleys +500t Make Great Progress

 A few days ago, another heavy equipment was officially put into use at Weihua Crane Intelligent Industrial Park. A 16m×8m×6m heat treatment annealing furnace for heavy structural parts successfully realized the overall annealing of a 320t metallurgical trolley.

 

As the core process and processing technology of large metallurgical cranes, this large annealing furnace can meet the annealing treatment of various structural parts of large metallurgical cranes with capacity above 500t, and the equipment processing capacity has reached the leading level in the lifting industry.

1. Precise temperature control

The furnace temperature control accuracy is ±3℃, and the furnace temperature uniformity in the same zone is ±10℃. It adopts PLC control mode to automatically realize multiple heating processes.

 

2. Intelligent control

Three-dimensional heat storage, zoned furnace temperature control, nozzle size and layout can be set according to actual needs, so that the workpiece is evenly heated in the furnace.

 

According to the product structure, Weihua has formulated a special annealing process, which can improve or eliminate various structural defects and residual stresses in the welding process, improve the comprehensive mechanical properties of the workpiece, prevent fatigue deformation damage and weld joint cracking, and eliminate Potential safety hazards to ensure the dimensional stability of each organization.

 

 

Overall processing capacity of large metallurgical crane reducer:

 

1.Full-size processing capacity

With large-scale CNC floor boring and milling machines with 260mm and 200mm spindles, CNC gantry boring and milling machines and other equipment, as well as corresponding processing tools, it has a full-size, high-precision processing capability coverage for large metallurgical crane structural parts of 300t-500t and above.

 

2.Combined process & combined processing

The processing mode is transformed from single-piece processing to combined processing, and the whole process quality control mode is constructed.

 

3.Overall machining accuracy

It can realize the combined processing of large components and full-size large area, multi-directional boring, milling, and drilling. The linear positioning accuracy is 0.02mm, the axis parallel accuracy of each hole system is 0.015mm, and the flatness of the joint surface is good.

 

Weihua carried out many metallurgy crane projects for many big steel plants in China and overseas.

Crane Steel Wheel

Crane wheels are for overhead crane, gantry crane, casting cranes, bin loading cranes, slab handling cranes, steel coil clamp cranes, magnet cranes, etc. in the metallurgical plant. Crane wheel forging materials: 60#, 65Mn, 42CrMo. 

 

Features of Crane Wheels:

1. Application scope: Sustaining the overhead crane or gantry crane

2. Weihua crane wheels adopt ZG430-640 cast steel, and thermal treatment on surface.

3. Surface hardness of our crane wheels is HB 300-350, and depth of quenching is more than 20mm.

Wire Rope Guide

Rope guide is also called wire rope arranging device used to make crane steel wire rope neatly arranged around the drum to avoid wire rope circles in a mess or overlaps causing malfunction to Electric Hoist, or even destroy the hoist. Crane rope guide can guarantee the normal working of electric hoist, and extend the service life of wire rope and drum.

Rope guide

 

1. Application: Rope guide for electric hoist wire rope guide.

2. Rope guide is also called rope arranging device.

3. Its function is to make wire rope neatly arranged around the drum, in case wire rope circles in a mess or overlaps cause malfunction to electric hoist, even destroy the hoist.

4. when rope guide is running, it gets a large lateral force. That causes brakes. Wire rope guide is the most easily damaged part of electric hoist.

5. Its interchangeability is good.

Crane Brake

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.
