Shaped beam is formed by butt welding of two steel sections after heat treatment. Profile beams are mainly used for roof support in coal mine tunnels or tunnels, and are used in conjunction with single hydraulic pillars to form a metal bracket to support the roof beam.
The profiled beam can be combined with various types of monomers and metal pillars to form a metal bracket, which can be used in horizontal and gently sloping mining working faces and machine heads or other large roof control areas in coal mines. The profiled beam can be cantilevered over long spans. The roof of the controlled roof area is supported with a type support to achieve a larger working space without pillar support on the working surface, creating favorable conditions for improving working conditions and adopting new coal mining machinery and bendable conveyor cashiers.
How to load and unload profiled beams
When loading profiled steel beams and single hydraulic props on the ground, two people are required to cooperate, apply force evenly, and at the same time let go and put them into the mine car.
The loading volume of profiled steel beams and single hydraulic props must strictly comply with the relevant laws and regulations of the industry department.
Other materials and accessories such as profiled steel beams and single hydraulic props are handled and loaded manually and transported by mining trucks.
When unloading underground, it is necessary to choose a position where the bracket is strong and reliable and the roof is intact. Specific requirements: (1) When manually unloading the pillars, the mine car must be stabilized first, and then people must cooperate to move the pillars away from the mine car. Lean forward on the designated alley. ⑵. When using manual unloading of profiled steel beams, people must cooperate to place the profiled steel beams in designated locations and stack them. It is strictly prohibited to throw them randomly after taking them out from the mine car.
Loading and unloading requirements for profiled beams
After arriving at the mine, profiled steel beams and single hydraulic props must be inspected for various technical indicators in accordance with regulations, and they can only be used in the well after passing the standards.
Hydraulic components, brackets and supports should be sealed with plastic covers before handling to prevent dirt or debris from entering.
