Products Description
Screw Type House Jacks are heavy-duty construction screw shoring jacks, built on the same trapezoidal Tr lead screw system as SWL screw jacks. The full series includes SWL2.5 ~ SWL120, with max lifting strength from 25kN to 1200kN. Designed for temporary building shoring, foundation correction and large component leveling, this screw type house jack can withstand lifting thrust and pull force, operated manually or by motor. It can work as single-point support or multiple linked units for synchronous jacking. Widely applied in factory foundation repair, precast component support, formwork load bearing and steel structure leveling. With standardized parameters and customizable lifting stroke, it serves as reliable mechanical screw support equipment for heavy civil engineering and large structural lifting projects.
Product Characteristics
Full range of tonnage options
Screw type house jacks cover complete models from SWL2.5, SWL5, SWL10/15 up to SWL120, paired with Tr trapezoidal threads. Max lifting strength ranges from 25kN to 1200kN, covering applications from light shoring to ultra-heavy building lifting.
Standardized weight calculation data
Screw type house jacks provide main unit weight without stroke and screw weight per 100mm. It helps contractors quickly calculate total weight, check foundation bearing capacity and design hoisting plans to simplify pre-construction calculation.
Dual-direction load capacity for thrust and pull
Screw type house jacks can take upward lifting force and downward pull force. Each model has defined rated max lifting strength and max pull force, meeting engineering needs for jacking up and component tension fixation.
Product advantages
Heavy-load self-locking for long static support
Screw type house jacks adopt self-locking Tr trapezoidal thread. Once adjusted to target height, the position stays locked and load will not slip. Perfect for long-duration static shoring in construction without hydraulic pressure loss risk.
High-strength integrated structure & deformation resistance
Housing and lead screw of screw type house jacks are quenched and tempered for reinforcement. Ample load margin prevents deformation under site vibration and alternating load, delivering stable long-term support for heavy structures.
Flexible driving and linkage solution
Screw type house jacks support hand crank and electric motor drive. Multiple units can be linked via drive shafts to realize synchronous lifting for large building components and reduce structural offset risk.

FAQ
Q: What load range can screw type house jacks support?
A: Our screw type house jacks adopt SWL series specifications. The models range from SWL2.5 to SWL120, with max lifting strength from 25kN up to 1200kN, available for light to heavy construction shoring tasks.
Q: Does screw type house jack support both lifting thrust and pull force?
A: Yes. This screw type house jack can bear lifting force and pull force. Each model has clear rated max lifting strength and max pull force, suitable for both jacking down and pulling applications.
Q: What thread structure is used on screw type house jacks?
A: Screw type house jacks use trapezoidal Tr screw thread. Different models match different thread sizes such as Tr30*6, Tr40*7, Tr100*18 and Tr180*25 for heavy load transmission.
Q: What does weight without stroke mean for screw type house jacks?
A: Weight without stroke refers to the weight of jack main body excluding extended screw. The screw weight per 100mm is used to calculate extra weight when customizing longer stroke for construction projects.
Q: Can multiple screw type house jacks work synchronously for big structure lifting?
A: Yes. Screw type house jacks can be connected by drive shafts to achieve synchronous lifting. It is widely used for multi-point support and leveling of large precast components and steel structures.
