PRODUCTS & CASES

Straightener roller replacement overhead cranes are fully automated lifting machines dedicated to disassembling and installing straightener rollers on metal straightening equipment. Within metallurgical rolling production lines, various roller specifications need frequent swapping to meet diversified metal shaping processing standards.

Previously, all automatic roller-changing lifting equipment used by domestic steel plants relied entirely on overseas imports. Leveraging self-owned patented technology and independent intellectual property rights, Weihua successfully developed domestically manufactured fully automatic roller replacement overhead cranes. This breakthrough eliminated foreign technological monopoly, with all working performance metrics reaching world-class advanced levels.

The official launch and delivery of this specialized crane greatly advance digital automatic transformation for the steel rolling sector. It stands alongside other landmark intelligent crane products from Weihua, including automatic steel pipe distribution cranes supplied to Baotou Iron & Steel, automated feeding cranes for Chengde nickel smelting lines, and multi-point intelligent casting overhead cranes delivered to China Steel Infrastructure.

Weihua’s complete series of overhead lifting equipment is extensively deployed across mechanical processing, metallurgical rolling, power generation, railway transport, port logistics, petroleum exploitation and chemical manufacturing industries. Our cranes have supported numerous national key infrastructure projects and production bases of large industrial conglomerates.

1. Intelligent precise positioning control system guarantees millimeter-level accurate placement of straightener rollers during replacement cycles

2. Built-in anti-sway algorithm stabilizes the whole handling process and eliminates violent swinging of heavy roller components

3. Matched automatic hydraulic clamping fixture and exclusive customized lifting spreader specially designed for roller grabbing

4. Multi-group synchronous hoisting capability allows simultaneous disassembly and installation of up to 10 roller assemblies in a single operation

5. High-sensitivity sensor detection modules monitor the entire workflow in real time to lock out all potential operational safety hazards

Standard Automatic Working Sequence

Hoist straightener rollers → Precise spatial positioning → Complete roller disassembly & replacement → Lock rollers into designated installation position
