FOCUSING ON - GAS SPRING SOLUTIONS.

THE SIMPLEST AND MOST EFFECTIVE WAY TO SOLVE
SPRING, LIFT AND COUNTERBALANCE CHALLENGES.

It is no exaggeration that KALLER is the gas spring company standard within press tools for nearly all major car manufacturers, such as GM, FORD, Daimler Chrysler, TOYOTA and many more.

Strömsholmen in Tranås, the leading developer of gas spring technology, manufactures and supplies approximately half the world's demand in this market sector.

FOCUSING ON - INGENUITY.
Gas springs make use of the simple fact that gas pressure creates a force that is proportional to the surface area with which it makes contact. This means, the piston rod in the gas spring is used as a spring element.

A gas spring will also generate a much greater force and longer stroke than an equivalent mechanical spring. What is more, in many cases Life Cycle Costs and installation costs are considerably lower than those for conventional springs. Since the Nitrogen gas pressure can be easily checked and regulated, in many respects, gas springs are far superior to other types of spring element.

FOCUSING ON - DIVERSITY.
The development of products using gas spring technology continues steadily forward. The following examples show some interesting challenges where gas spring technology is used in mechanical and vehicular applications (MAV).

Consider them as pure inspiration. Naturally, we are only glad to help tailor make solutions for specific applications. It is quite probable that the inventions of today will be common place tomorrow.

FOCUSING ON - CAPABILITY.
Challenge:

To reduce the size, weight and transmission dimensions of an industrial robot.
Solution:
Counter balancing KALLER gas spring. Robot arms, used for lifting both large and small objects, are most often counterbalanced in order to maximise their reach potential.
For counterbalance applications, gas springs have many advantages compared to mechanical springs. Gas springs are capable of producing a high force, whilst at the same time minimising inbuilt dimensions. The balancing force can be easily adjusted by simply altering the gas filling pressure. Total costs and running costs can also be reduced.
In Tranås we have developed a special series of counterbalance gas springs with extremely long service lifetimes.They can be found in a variety of different counterbalance applications, like the robot pictured here for instance.

FOCUSING ON - CONTROLLABILITY.
Challenge:

Compressed waste bales have a tendency to get stuck in the waste compressor making it often difficult to release them.
Solution:
KALLER Lockable gas springs which when activated, lift and turn out the bale from the compressor.
By working in collaboration with Orwak, an effective solution to the problem was found.
Orwak waste compressor units, amongst others, are used by large grocery stores to compress together food cartons and other paper waste.

FOCUSING ON - FLEXIBILITY.
Challenge:
Maintaining drive-belt tension when driving track-laying vehicles. 

Solution:
KALLER gas springs.
Respective driving and breaking forces are absorbed by the arm-linkage that regulates
the tension in the drive belt which in turn is controlled by a KALLER gas spring. The gas springs provides he counteracting force needed to give a smooth transition between driving and breaking conditions. As one can also imagine, this variable tension force can be adapted to suit speed and terrain.

FOCUSING ON - SAFETY.
Challenge:

The arm-linkage system on a dump truck causes the rear flap to open and close as the truck body is raised and lowered.The arm linkage is at risk of being damaged should a rock or other hard object prevent the rear flap from closing.
Solution:
KALLER gas spring within the arm-linkage to be compressed and absorb the force if such a blockage occurs. This solution was developed and implemented by working in co-operation with Volvo Construction Equipment.

FOCUSING ON - SIMPLICITY.
Challenge:

Timber felling chain saw chains and drive mechanisms are subject to great forces. It is therefore important that the tension of the saw chain is checked and adjusted regularly.
Solution:
Pure and simple. An adjustable KALLER gas spring used to stretch the chain after every felling.
This solution was developed in collaboration with Sandvik.

FOCUSING ON - FUNCTIONALITY.
Challenge:

To provide a secure and durable clamping force.
Solution:
KALLER gas/hydraulic spring system uses gas pressure to provide the large clamping force required to hold the drilling rods in place and uses hydraulic pressure to release this force when necessary.

This solution was developed in collaboration with Atlas Copco.

FOCUSING ON - ADAPTABILITY.
Problem:

Reduce the number of vehicles around the airport.

Solution:
Push-and-pull vehicles are used to transport luggage trains and taxi aircraft in and out of their respective gates. KALLER gas springs are used to eliminate sudden shockloads when towing luggage train carriages and are also used to protect the front landing gear of aircraft.

FOCUSING ON - POTENTIALITY.
Challenge:

To increase the loading capacity and speed of rail traffic, whilst at the same time protecting the running gear from damage by dynamic loading.

Solution:
Specially developed heavy duty gas springs. According to calculations, this con-ceptual solution would allow a 20 % increase in loading capacity and likewise a 20 % increase in rail speed if existing mechanical springs were replaced with special KALLER gas springs.

FOCUSING ON - OPPURTUNITY.
Challenge:

Seismic vibrations transmitted to building structures during earthquakes often cause catastrophic damage.
Solution:
KALLER gas springs within the building structure that absorb such vibrations, leaving the structure still standing after an earthquake.
 
ECCENTRIC? PROBABLY. UNREALISTIC? ABSOLUTELY NOT!
These gas springs have yet to be commissioned, but we are more than ready to develop such a product.
