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, reducing 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.

Specifications

  • Plunger diameter: Up to 8”
  • Cylinder diameter: Up to 10”
  • Joints: Threaded/Non-Welded

Standard Equipment

  • Plunger
  • Cylinder
  • Grooved inlet/outlet with a diameter of 2” and 3”
  • 1 1/8” threaded plunger cap
  • Single wrap tapecoat

Two-Stage Telescopic

Jacks

two stage jack

Two-Stage Telescopic

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, reducing the number of separate components to coordinate and install.

Smooth, Consistent Operation

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

Specifications

  • 2.50”
  • 1st stage plunger: 2.408” diameter
  • 2nd stage plunger: 3.348” diameter
  • Cylinder: 4.756” diameter
  • 2.75”
  • 1st stage plunger: 2.754” diameter
  • 2nd stage plunger: 3.937” diameter
  • Cylinder: 5.593” diameter
  • 3.50” (subject to change)
  • 1st stage plunger: 3.341” diameter
  • 2nd stage plunger: 4.720” diameter
  • Cylinder: 6.693” diameter

Standard Equipment

  • Dual jack/post setup
  • Round base plate with locating pin or rectangular base plate
  • Grooved inlet/outlet with a diameter of 2”
  • Bleeder/Recuperator port location 130° and 230° from inlet

Optional Items

  • Threaded (NPT) male inlet
  • Custom bleeder/recuperator port valve location in 10° increments, always 100° apart
