Manual Cable Bolt Destressing System

Destressing Where There Is No Power

In a freshly driven roadway the air main and power cable may not have reached the face yet, and in old goaf edges or return-airways there is no utility at all. The TS-series Manual Cable Bolt Destressing System needs neither: a worker strokes the SYB-2S hand pump, the jack grabs the cable, pulls the wedges loose, and releases. It is the default tool for patch destressing, maintenance pulls, and supplementary cable work where powered rigs cannot be deployed. Because the hand pump needs no air-line connection, a crew can carry the whole set into a remote heading on foot.

The SYB-2S pump delivers 2.3 mL per stroke at high pressure and 14.5 mL at low pressure at roughly 350 N hand force, on a 2.0 L tank and a 10 kg pump body, capped at 63 MPa oil pressure. Seven TS models span 15.24-35 mm cables at 300-700 kN, with 70-100 mm strokes and 18-29 kg jack weights.

There is no motor, no valve block, and no air motor to service, so underground crews can handle routine maintenance themselves. The tool anchor uses the upgraded material and heat treatment common to TRUYOU mining equipment Co.,Ltd destressing tools, which lowers the replacement frequency crews see on ordinary hand units; field feedback from private coal operations in Shanxi and Inner Mongolia describes the rig as durable over years of low-frequency use.

The manual model sits below the pneumatic and electric versions in price, which suits budget-conscious or low-frequency buyers. The hand-pump design also keeps spare-part stocking simple, with few consumables beyond the tool anchor and seals. MOQ is one set, mixed models are allowed, and stock units dispatch within 1-2 days. Quality reports ship with the goods, and a 12-month warranty applies under normal use.
