The RockSmith 25 tonne mono-strand hydraulic jack is the primary tool for tensioning in the Civil and Construction industries.

This jack is ideal for post-tensioning and pre-tensioning. Striking the balance needed between versatility and practicality, it is incredibly rugged while still lightweight and has the capacity to tension strand up to 15.7 mm in diameter - beyond 80% minimum strand breakage force.

A large range of accessories and spares are kept in stock to meet orders with minimal delay.

Features:

• Quickly configurable to suit a wide range of strand sizes
• Designed to ISO4413:1998 for hydraulic equipment
• Hard chrome ram and bronze seals ensure super-low friction and maximum durability
• Specialised jack wedges to maximise strand loading
• Specialised spring-loaded nose cones
• Available with ports positioned together (Normal) or separated (Direct)
