The BTE Mid-Western FL7 is a pneumatic feed leg engineered to pair with the BTE Mid-Western S83 jackleg drill platform for production rock drilling in mines, tunnels, and quarry walls. Configurable in 36 in., 42 in., 54 in. leg lengths to match drilling reach across stope, tunnel-heading, and bolt-pattern work. Mining, tunneling, and rock-bolt crews specify it for hands-free production drilling on the established Gardner Denver-pedigree S83 platform.
- Pneumatic feed leg engineered for the BTE Mid-Western S83 jackleg rock drill, the U.S. industry-standard production rock-drill platform.
- Power-retract pneumatic cylinder pulls the leg back automatically; the productivity feature high hole-count crews specify for production-shift drilling.
- Available in 36 in., 42 in., 54 in. leg-length variants; choose by drilling reach across stope, tunnel-heading, and bolt-pattern work.
- Pairs with the BTE Mid-Western S83FA, S83FB, S83FC, and S83FD jackleg-drill configurations across 7/8 in. and 1 in. hex shank options.
- Pneumatic feed cylinder runs on the same compressed-air supply feeding the drill, no separate hydraulic power pack or electric system to maintain.
- Built for production rock drilling, tunnel-roof bolting, anchor-hole drilling, and rock-bolt installation in underground mining and tunneling.
- Crowder Supply stocks the BTE Mid-Western feed-leg range; the BTE Mid-Western FL7, S83 jackleg drills, swivel adapters, and replacement components.
- BTE Mid-Western manufactures the S83 platform in the United States to the original Gardner Denver design, with industry-leading parts depth for U.S. rock-drilling crews.
