The LXG suspension (over-rail) crane is a special crane equipment for the power plant coal-fired system for the generator set. Its main purpose is to overhaul the coal mill. The working level is A1-A3, and the working environment temperature is -25°C-+40°C. It is not advisable to lift molten metal or toxic, flammable or explosive materials.
This product is a combination device consisting of an electric hoist trolley, an electric double-beam suspension crane (main vehicle), a (hand) electric single (double) beam suspension crane (sub-vehicle) and an over-track device. The electrical system is operated and controlled via push button switches.
