Narrow Chassis Twin-Boom Roof Bolting Rig

Product Introduction

This equipment is suitable for construction scenarios where large machinery requires passing space in roadways or for bolting operations in narrow roadways. With a body width of only 700 mm and remote-controlled moving, it facilitates safe vehicle passing. The high single-grouser track provides good site adaptability, making it suitable for surfaces with significant mud or loose coal. Equipped with various electrical devices such as explosion-proof switches, lighting lamps, and methane power cutoff devices, it offers high intelligent expandability.
