GEDORE Bodywork and Lever Tools
The Law of the Lever in Tool Practice
The principle is simple: The greater the distance between the point where force is applied and the fulcrum, the higher the torque at the load point can be. In simplified terms: force × effort arm = load × load arm.
In practice, this means that a longer lever can reduce the force required. In return, the movement at the workpiece becomes smaller and the load on the tool, component and point of application increases. The lever must therefore suit the task, the available space and the expected load. This is the reason for the different designs of Lever Tools.
Nail Bars: Breaking Open, Releasing, Pulling
When a crate needs to be opened, formwork released or a nail pulled, a nail bar is the classic choice. The GEDORE 120 series is listed in lengths from 350 to 1,000 mm.
Length not only determines the possible leverage. It also affects whether work is possible in confined spaces, how well the tool can be controlled and whether the point of application can be reached.
Typical situations:
- Carefully separating boards or crates
- Pulling nails out of wood
- Slightly lifting components to insert a support
- Creating distance between the tool and a possible pinch point
- Establishing a stable point of application on construction sites or during dismantling work
Lever Tools: Powerful Levering over a Short Distance
GEDORE offers various Lever Tools for different points of application and working conditions. The range includes, among others, the 139-400 Roller Head Lifting Iron and the 292 and 293 Lever Tools. The main difference with the roller head lifting iron lies in the shape of the head and the rolling effect, which significantly increases leverage. While a conventional pry bar, often known as a crowbar or wrecking bar, usually has a flat, slightly curved claw or edge, the roller head lifting iron has a spherical or roller-shaped rounded head, the “roller head”.
This helps with selection: For a confined working area, a shorter model may be easier to control. If greater reach is required, a longer version is suitable. Where a defined point of application is important, the respective head or end shape can be decisive.
Practical examples:
- Lifting a cover or trim without reaching into the gap with the fingers
- Releasing a component from its fit during removal
- Holding a machine part in position during installation
- Compensating for a small difference in height before inserting a support
- Initiating a controlled separating movement during dismantling work
Mounting Irons: Aligning Instead of Striking
During installation work, maximum force is often not the objective, but rather controlled movement by a few millimetres. Three tools have proven useful in practice: While the 137-600 Mounting Iron, with its flat spoon-shaped ends, is primarily used for non-destructive levering of tyres and components, the 136-500 Assembly Tip is a long, tapered pin designed specifically for precisely aligning bolt holes and bringing them into line. The 138-400 Bending Iron, on the other hand, differs fundamentally from both because it features special slots or pins for deliberately bending metal parts such as flat steel or pipes into shape.
A mounting iron can help when aligning components, for example when holes, flanges or fits are not yet exactly aligned. The tool is positioned as close as possible to the intended point of application and the component is moved only as far as necessary for the next installation step.
Typical applications:
- Aligning holes on a flange
- Positioning a machine part while bolting it in place
- Aligning components before the connection is finally tightened
- Carefully releasing a fit during removal
- Correcting components over a limited distance during maintenance

Answers to the Most Frequently Asked Questions
A nut splitter is useful when a nut is so heavily corroded, seized or deformed that it cannot be loosened with a spanner or by cutting without damaging the thread or shaft. The nut splitter splits the nut open in a controlled manner while protecting the surrounding component.
The decisive factor is the width across flats of the nut to be split. GEDORE offers mechanical versions for widths across flats from 10 to 36 mm and hydraulic versions from 7 to 36 mm. A set is a good choice for anyone who regularly works with varying nut sizes.
The mechanical nut splitter is operated manually via a screw. It is compact and suitable for most standard applications. The hydraulic nut splitter generates force via a hydraulic piston, enabling a more even build-up of pressure and higher forces. It is particularly advantageous for very large or heavily corroded nuts.
Dismantling and assembly forks are used to separate two components by engaging the joint with a wedge-shaped action, for example on ball joints or tie rod ends in automotive applications. They are designed to protect the surfaces of the components. The appropriate fork width depends on the diameter of the connection to be separated.
Yes. Spare chisels are available separately for all GEDORE nut splitter versions. This allows the tool to be economically restored after wear without having to replace the entire nut splitter.
The category includes seal ring installation tools, installation tools, shaft seal installation tools and setters, among others. Many versions are assigned to automotive applications.
No. A longer lever can increase the force effect, but requires more space. Shape and accessibility are equally important.
The type of damage, component contour and accessibility vary. Multiple shapes provide different points of application and counter-support surfaces.
