Battery Rail Transfer Cart for High-Temperature Furnace Doors in Steel Plants

Pain Point Analysis
A large steel plant's high temperature workshop faces the challenge of low efficiency in furnace door transportation. Traditional electric transfer carts are limited by difficult track conversion, requiring manual direction adjustment and causing process interruptions. The temperature around the furnace body remains above 200°C for long periods, making ordinary steel structure frames prone to deformation. Additionally, there is a risk of lateral tilting during furnace door hoisting.

Solution
A 10 ton hydraulic lifting battery rail transfer cart developed for high temperature and heavy load scenarios uses a cast steel box girder frame to ensure structural stability under high-temperature conditions.

The original hydraulic jacking + steering wheel simulation system enables 90° synchronous steering of four wheels. Combined with the workshop's existing vertical and horizontal rail network, it completes direction changes within 5 minutes—3 times faster than traditional methods. The central sunken hydraulic platform is equipped with a deformation resistant bracket, and dual-motor drive allows smooth lifting and fine-tuning of ±50mm, ensuring precise docking of furnace doors with A/B furnace bodies.

Innovative Applications
The intelligent coding system of the rail transfer cart automatically memorizes the coordinates of each furnace body. After operators set task sequences via wireless remote control, the equipment independently plans transportation routes. During operation, audible and visual alarms are linked to start/stop functions, forming a three-level safety protection system together with emergency stop buttons. Batteries support 8 consecutive hours of operation, with real-time battery level displays on the power screen, enabling zero-wait turnover in line with the workshop's production rhythm.
