· ​Optimized 270 kN Capacity: Specifically engineered to handle the exact ultimate tensioning force required for 0.5" and 0.6" mono-strand post-tensioning tendons in commercial floor slabs and transfer beams.
· ​Integrated Power Seating Mechanism: Features a built-in wedge seating mechanism that simultaneously pulls the strand and seats the anchor wedges with absolute precision and repeatability.
· ​Lightweight & Ergonomic Design: Constructed from high-strength aerospace-grade alloy materials, significantly reducing operator fatigue during repetitive slab-tensioning cycles.
· ​Full Hydraulic Traceability & Safety: Equipped with over-pressure relief safety valves and leak-proof quick-connect hydraulic couplers, ensuring total reliability when paired with standard electric hydraulic pumps.
​Engineered for high-efficiency post-tensioning operations across modern civil and building construction:
· ​Commercial & Residential Building Slabs: Post-tensioned flat-plate floor slabs, waffle slabs, and high-rise commercial tower construction.
· ​Heavy Industrial Structures: Foundation mat anchoring, heavy equipment base blocks, and large structural storage silos.
· ​Bridge & Infrastructure Maintenance: Bridge box girder internal tendon stressing, repair maintenance, and structural tie-back stabilization.
​Q: Which strand diameters are compatible with this 270 kN mono strand jack?
A: This jack is standardly equipped with interchangeable nose pieces and anchoring wedges to effortlessly accommodate both 12.7 mm (0.5") and 15.24 mm (0.6") 7-wire PC strands.
​Q: What type of hydraulic pump is recommended to operate this jack?
A: It is designed to operate seamlessly with standard high-pressure electric hydraulic pumps rated up to 63 MPa (9,100 psi) featuring multi-way control valves for smooth advance and retract cycles.
​Q: What is the standard export packaging and transport safety?
A: Each hydraulic jack is carefully packed inside a heavy-duty, reinforced wooden export case with protective foam lining to prevent mechanical impact or hydraulic contamination during international transit.
