Cable Bolt Tensioner For Mining
Mechanical Actuator for Strand Tensioning
The Cable Bolt Tensioner for Mining functions as the mechanical execution unit within an underground roof support system. It operates independently of a dedicated power source, allowing integration with pneumatic, electric, manual, or hydraulic pump stations. This modular setup provides site managers with the flexibility to pair the jack with existing mine infrastructure, thereby reducing the need for additional power generation equipment.
Weight Reduction and Tool Anchor Durability
The cylinder body is manufactured from high-strength alloy materials with optimized wall thickness. The unit weighs 20% to 30% less than conventional counterparts, facilitating single-person transport and alignment in restricted roadways.
High-hardness steel strands exert significant friction on the internal tool anchor during operation. The structural design and heat treatment protocols for this component have been modified to extend its replacement cycle. This reduces the frequency of spare part swaps and associated downtime. Because the jack is supplied as a standalone execution terminal, buyers holding existing pump stations can procure the unit independently to lower initial capital expenditure.
Target Operating Conditions
When coupled with pneumatic or explosion-proof electric pumps, the tool manages standard pre-tensioning in gassy coal seams. For deep metal mines where ground stress is severe, 500 kN to 700 kN models deliver the necessary structural control. Initial support in tunnel excavations and large underground chambers is also achieved by applying standard design loads.
Production and Delivery
Customization covers non-standard stroke lengths and outer dimensions based on provided technical drawings or prototype requirements, with sample development spanning one to three months. Factory machining relies on CNC lathes, turning-milling compound machine tools, and machining centers. Every unit passes a 100% inspection protocol before dispatch. Packaging utilizes solid wood crates with quick-release stainless steel buckles. Internal parts are wrapped in bubble film and partitioned. Standard models remain in stock for dispatch within one to two days, while bulk or custom orders ship according to contractual schedules.

Procurement Inquiries
Q1: Can the jack be purchased separately without the hydraulic pump?
A1: Yes. The unit is sold as a standalone execution part. If you have an existing pump station, confirm the interface connection to integrate directly, saving on complete system costs.
Q2: Do you offer models matching our local steel strand dimensions?
A2: Yes. The center hole diameter ranges from 18 mm to 38 mm, accommodating strands from 15.24 mm to 35 mm. Provide your wire diameter during ordering to ensure proper model matching.
