In heavy-duty environments like agriculture, plant machinery, and industrial maintenance, removing seized or stubborn components is rarely straightforward. While traditional legged pullers are often the go-to tool, there are many situations where they simply can’t get the job done.

This is exactly where the Sykes Pickavant 20960000 – 20T Hydraulic Internal Thread Puller comes into its own.

The Problem: When External Grip Isn’t an Option

Conventional pullers rely on external gripping legs to latch onto a component. But what happens when there’s nothing to grip?

Engineers and technicians regularly face challenges such as:

• Flush or recessed components
  Shafts, pins, or bolts that sit flush within a housing leave no exposed edge for puller legs to grab.
• Restricted access
  Tight spaces or surrounding components prevent proper positioning of a traditional puller.
• Risk of slippage or damage
  External legs can slip under high load or damage surrounding parts, especially on worn or irregular surfaces.
• Heavy-duty applications requiring higher force
  Standard mechanical pullers often struggle to deliver the controlled, high force needed for large agricultural or industrial assemblies.
• Delicate or precision components
  Uneven pulling force from legged pullers can distort or damage parts that require careful extraction.

In these situations, technicians are often forced into time-consuming workarounds, or worse, resort to destructive methods.

The Solution: Internal Thread Pulling with Controlled Hydraulic Force

The 20T Hydraulic Internal Thread Puller eliminates these challenges by completely rethinking the pulling method.

Instead of gripping externally, it works from within.

By threading a high-tensile pull rod directly into a pre-tapped hole (or one that can be created), the tool applies force exactly where it’s needed, from the centre of the component.

Why This Matters

This internal pulling principle delivers several key advantages:

• Works where legged pullers can’t
  No external grip required, perfect for recessed, flush, or inaccessible components.
• Direct, aligned pulling force
  Reduces stress on surrounding parts and ensures a clean extraction.
• Greater control with hydraulic power
  The 20-tonne hydraulic ram provides smooth, even force, minimising the risk of sudden movement or damage.
• Improved safety and reliability
  A stable setup using a heavy-duty cross beam and twin support legs ensures load is evenly distributed.

Real-World Applications

This tool is particularly valuable in environments where components are large, heavily loaded, or exposed to harsh conditions:

• Agricultural Machinery - 
  Removing seized hitch pins, shafts, or bolts from tractors and implements
  Extracting components exposed to corrosion, dirt, and high loads
• Construction & Plant Equipment
  Pulling large pins or shafts from excavators and heavy machinery
  Working in confined spaces where access is limited
• Industrial Maintenance
  Removing precision components without damaging housings
  Installing new pins using the included striking plate without harming threads

Built for Heavy-Duty Performance

The design of the 20960000 reflects the realities of industrial use:

• Thread compatibility: M12, M14, M16, M18, M20
• Maximum bolt length: 830mm
• Adjustable spread: 104mm to 293mm
• 20-tonne hydraulic cylinder for high-force applications
• Robust construction for demanding environments

With the addition of a compatible hydraulic hand pump (optional), operators gain full control over the extraction process.

A Smarter Approach to Extraction

When traditional pullers fall short, the cost isn’t just time, it’s also potential damage, safety risks, and unnecessary frustration.

The Sykes Pickavant 20T Hydraulic Internal Thread Puller offers a smarter, more controlled alternative. By shifting from external grip to internal force application, it solves some of the most common and costly challenges faced in heavy-duty extraction work.
