Two-Stage Telescopic Holeless

Jacks

Telescopic jacks are a multi-stage hydraulic solution designed for applications requiring greater travel. By using multiple stages, this configuration achieves extended travel within a single jack assembly while maintaining a similar footprint to a single-stage jack.

Extended Travel in a Compact Design

Provides greater travel within a single jack assembly without significantly increasing overall length.

Self-Contained Multi-Stage Design

All stages are integrated within the jack, minimizing the number of separate components to coordinate and install.

Smooth, Consistent Operation

Multi-stage design provides steady, consistent movement throughout travel.

See Quality in Action

Every two-stage telescopic jack is precision tested before it leaves our facility, verifying full-stroke operation, proper stage sequencing, operating pressure, and more.

But performance is only part of the story. Our jacks are also prefilled and ready for installation, helping crews save time in the field while minimizing startup and bleeding challenges.

From precision testing to easier installation, it's all part of delivering a jack you can install with confidence.

Single Stage In-Ground

Jacks (Borehole)

In-ground (borehole) jacks are a proven hydraulic solution installed below ground. This configuration provides dependable performance with a straightforward mechanical design and is typically used in new construction or in modernization projects where an existing borehole is already in place.

Supports Higher Capacity Applications

Well-suited for higher capacity requirements, including passenger, hospital, and freight applications.

Simple and Direct Design

A direct configuration without posts or roping reduces the number of components within the system.

Well-Suited for New Construction

Ideal for new construction projects where a borehole can be incorporated into the building design.
