Advantages of Cross Roof Beam

Durability: Cross roof beams pass the test of time, and they are solid and will not splinter or warp like timber beams.

Cost-effective: Cross roof beams are less expensive than many other materials. Once they arrive on the worksite, the beams are ready to be installed without labor-intensive prep work.

Termites or rodents cannot attack them.

Cross roof beams are relatively light, weighing less than concrete or timber and reducing transportation fees.

Steel can endure significant tensile stress, so no bending or breakage issues exist, if calculated properly.

High-standard structural integrity results in enhanced safety.

Cross roof beams are resistant to corrosion and fire.

π Type Steel Girder

Our π Type Steel Girder has many application advantages, in terms of material strength, the height of π Type Steel Girder can effectively support the roof, prevent collapse, and ensure the safety of underground work in mines.In terms of adjustability π Type Steel Girder can be adjusted according to the different heights of the working face in the actual mine to adapt to different working conditions.

A-type Beam Shape

Our A-type beam shape is exported to major groups and national coal mines, because our improvement of process and production equipment has greatly improved the quality and efficiency of our products, especially after joining the production from our automatic welding robotic arm, which reduces some uncontrollable welds and other defects caused by manual welding, so that our product quality has changed qualitatively.

DFB Metal Long Beam

DFB Metal Long Beam is a key equipment in mine support, which is mainly used for roof support of underground coal mine working face to ensure the safety of coal mining operations.And we focus on the development and production of coal mine support equipment, our production of DFB Metal Long Beam every raw material has been inspected by our quality inspection department.

Installing Cross Roof Beam

Securing and Aligning Beams

Once the cross roof beams have been lifted into place, it's essential to secure and align them properly. Temporary bracing and supports should be used to maintain the stability and level of the beams during installation. It prevents any potential shifting or movement, which could compromise the integrity of the structure.

Welding and Cutting Safety

Welding and cutting are often necessary during cross roof beam installation. These processes present their own set of safety concerns, such as the risk of fire, toxic fumes, and exposure to intense heat and light. Proper ventilation, fire prevention measures, and personal protective equipment for welders should be in place to mitigate these risks.

Cross Roof Beam Applications

A common application for cross roof beam is for tunnel arches. Tunnels are used in underground storage vaults, in mining and in pedestrian pathways and vehicular roadways.

Cross roof beams are formed into a variety of shapes: Full circles, 180 degree segments, 180 degree segments with straight tangents (a horse-shoe tunnel support), and variations on the above. Typically tunnel supports are supplied with mounting plates with bolt holes. Within the mine, circular steel chutes called “liner cans” are sometimes used to transport ore. Again, structural steel supports these cans.

Steel shoring is often required when constructing vertical shafts for mines. In this case the beams are installed horizontally to contain the pressure of the side walls of the shaft.

After-Sales Service Is Solemnly Promised

Shandong Changmiaoxin Coal Mining Machinery Co., Ltd. attaches great importance to the after-sales service of products, under the premise of high-quality products, after-sales service is our company's first important commitment.The company has a professional after-sales service team, which region the products are sold to, which region has special after-sales service personnel, and in the sales area to establish offices, so as to help users select and design free of charge, train operators to learn theoretically, master the technical characteristics of the single pillar, and demonstrate ground operation.
