Hydraulic
Strand Jack with Synchronous Lifting System The working principle:
To integrate the prestressed anchor anchoring technology with the
hydraulic jack technology, anchor the steel strand through the
anchor, and then use the computer to centrally control the flow and
oil pressure output of the hydraulic pump station.
The device drives the jack piston to extend and contract
(displacement sensor device)and forces the steel strand and the
component to rise, descend, and continuously translate to realize
the overall synchronous lifting (translation) and lowering
movement.

FAQ:Q1: Whether the rig is used for rock holes or soil holes?A1: Equipped with different drill bits according to the application
object. Rock drilling rigs are equipped with round steel drill
impact hammers and rock drill bits. The soil drilling rigs
require a twist drill pipe and a three-blade drill bit. Q2: How much tonnage can a bridge jack lift??A2: The range is from 50 to 1000 tons, depending on the
application needs we have the right choice for you.
Q3: How many meters is the connection between the jack and the oil
pump?A3: The factory standard is two meters. If you need longer, we will
make it for you.
Q4: What is the difference between the hydraulic oil pump?A4: For the tension jack, it is 50 MPa 3 kW oil pump and 60
MPa 4 kW oil pump.Q5: What kind of packages does a set of anchors have?A5: Anchor ring, clip, anchor pad, spiral rib. Q6: Which payment term can you accept?A6: 100% T/T( Decide according to actual situation)
Q7: How long is the machine warranty?A7: One year for the machine and provide technical support
