Hydraulic jacks are essential tools for building prestressed
concrete buildings. Prestressed concrete is a technique for
increasing the strength and durability of concrete by adding
internal stresses before subjecting it to external loads.
Hydraulic jacks in prestressed concrete construction provide the
necessary energy to tension steel tendons or cables implanted in
the concrete. These tendons are often composed of high-strength
steel wires or strands. Tensioning the tendons compresses the
concrete, helping to mitigate the tensile pressures that will be
exerted on the structure during its service life.
Hydraulic jacks are used to gently and precisely impart tensioning
force to the tendons once the concrete has been cast and cured
sufficiently. The jacks are attached to the ends of the tendons and
actuated to pull them in opposite directions, stretching them and
exerting a compressive force on the concrete.
Once the desired tension is obtained, the tendons are securely
secured to the concrete with specialized anchoring mechanisms. The
stretched tendons create compression force, which serves to offset
the tensile stresses generated when the structure is loaded,
decreasing cracking and enhancing the overall strength and
performance of the concrete element.
1. The electric hydraulic jack is equipped with our factory's ultra-high pressure electric hydraulic pump station, which can realize jacking, pushing, pulling, extrusion (up, down, left, and right directions), and other types of operations, electro-hydraulic jacks are extensively utilized.
2. Simple presses (low or high-pressure types), bridge
displacement, falling beams, rubber bearing replacement (thin
synchronous jacks), static load tests, pile foundation detection,
trenchless engineering pipe jacking, large equipment jacking,
factory maintenance, and other industries have all seen widespread
use.
