1. What is Lifting Strand Jack?
|
Lifting strand jack essentially comprises the lifting cylinder and two anchor heads (top anchor and bottom anchor).
The strand cable is moved upwards or downwards by alternately opening and closing of the top and bottom anchor during the lifting stroke of the hollow piston.
This creates the load (G) lifting or lowering movement. |

2. How Does Lifting Strand Jacks Work?
Lifting Strand Jack in shaanxi zhongtuo are designed for strands with a diameter of 15.7 mm.
An admissible force of 120 kN is allowed per strand.
We offer strand jacks with a nominal load of 200 to 6,400 kN and a lifting stroke of 500 mm.
The series is designed to allow strand jacks for different rated loads to be easily combined Strand jacks with mechanical anchor heads (series PDM) are available for rated loads of up to 1,600 kN, and with hydraulic anchor heads (series PDH) for rated loads of up to 6,400 kN.
Optimum strand guidance is guaranteed by hardened guide plates at the anchor heads and suspension.
Telescopic strand guide tubes perform this function inside the hollow piston.
The basic equipment of the strand jack includes the following components:
• Load holding valve
• Connection for second strand jack
• 2 electrical pressure sensors to measure pressure on the piston and retraction side
• Linear potentiometer for piston stroke
• One linear potentiometer each for the wedge-seating stroke of the anchor heads (series PDH)
