Weihua crane three new crane products have been approved by the first batch of major technical equipment in henan province in 2019

Weihua crane welcomes "innovative triplets"!

"PTM26t electrolytic aluminium multi-function crane"

"QD150t roll changing crane"

"Gpb-306 shield piece hoist system"

Three new crane products passed through

The first batch of major technical equipment in henan province will be certified in 2019

Realize the first set of provincial recognition for weihua crane

Break again!!!

The first (set) of major technical equipment in henan province refers to the first (set) and first batch of equipment, systems and core components in China or in henan province with intellectual property rights after innovation and significant breakthroughs in varieties, specifications or technical parameters.

weihua crane PTM26t electrolytic aluminum multi-function crane

Its shell-cracking mechanism adopts the four-link structure, which can go deep into the crack of the block inside the electrolytic cell, reducing the resistance when the residual pole is pulled out, and improving the efficiency of pole changing.In guiding roller, anode clamp, hook, grab and other parts of the use of antimagnetic materials, the whole crane using insulation and monitoring control system, to achieve the safe operation of the crane in the strong magnetic field, improve the safety and stability of the operation.

Weihua crane PTM26t electrolytic aluminum multi-functional crane is the first one in henan province, which fills the blank of designing and manufacturing multi-functional cranes in henan province.On this basis, weihua crane has increased research and development efforts and technical reserves, digested and absorbed the experience and lessons from the design and production process, and made bold structural innovations, which have greatly improved the overall performance of the machine and made it capable of producing more tonnage electrolytic aluminum multi-functional cranes.

The product in the movable pulley group, USES the dislocation arrangement structure, realize interaction more strands of wire rope winding, design the PLC intelligent control system, with independent testing in automatic hydraulic driven by adding rope encoder on spreader, oscillation amplitude detection spreader, control of the hanging piece in the X, Y, Z three directions positioning accuracy and balance degree of deviation of sling.

Under the control of intelligent system, the synchronous replacement of several groups of rollers is ensured, and its quality reaches the domestic leading level among similar products, which is the best in henan province.

This system is the first three-piece hoist system in China. The whole machine adopts low headroom structure. The innovative wire rope guide device realizes the culvert turning and running in the narrow space inside the shield machine.The advanced electrical control system ensures the safe interlock and automatic positioning between various working stations.

The development of the segment hoist system has improved the efficiency of segment transport, and achieved a breakthrough in the key structure and application technology of the segment transport system in the construction of large shield tunneling machine.

Over the years

What are the first sets of products of weihua crane in henan province?

2018,Weihua crane yd250/80t-33m A6 forged crane

In 2018, weihua crane 660t fixed port mast crane
