Low Approach Slide Bed System

Case Study – Low Approach Slide Bed System

low_approach3

Opportunity – The vehicle recovery market has traditionally been supplied with hydraulic slide bed type vehicles for many years, these generally give an approach angle of between 7 -9 degrees depending on chassis and body length. This angle has been fine for the traditional type of vehicles but over recent years many cars are being fit with front end spoilers to make them handle better and improve fuel economy, these spoilers make the ground clearance very low and foul and become damaged when being loaded onto this type of vehicle.Continue reading

Mobile Platform Hydraulic Cylinder Development

Company profile

We have supplied equipment into the access industry for 20 years and working alongside our customers have developed a range of products that provide solutions helping to resolve problems encountered on certain applications.

Opportunity

mobile-1We were approached by a new customer HLS who were developing a new mobile platform for carrying out maintenance work and for picking products in a
warehouse environment. They had tried using traditional telescopic cylinders in their lifting column but had found them to be difficult to control as the speed varied as the cylinder extended and retracted during the lowering cycle the landing was hard causing operator discomfort.Continue reading

Elevator Telescopic Hydraulic Cylinder Development

Company profile

elevator-1C & C Hydraulics specialise in the design and manufacture of hydraulic cylinders for specific applications. The company was formed in 1994 and currently employs 30 people. We have supplied equipment into the access industry for 20 years and working alongside our customers, have developed a range of products that provide solutions helping to resolve problems encountered on specific applications.

Opportunity

We were approached by a leading lift manufacturer in the UK to look at the possibility of improving the operation of the telescopic cylinders they were using. The cylinders were a synchronised telescopic design but the customer wanted to add a cushioned landing and a cylinder reset after each cycle. They also wanted to keep the cylinder the same dimensions and foot print, making the room we had internally to accommodate the extra functions very tight.

Solution

elevator-2Our primary design objective was to create the cushioning system and simulate this operation on our in house vertical testing system. Upon testing we discovered we required a larger cushioned pocket and therefore created an extra oil gallery which allowed the cylinder to open uniformly.
Our second design requirement was to create the reset system. Initially we did this using a standard cartridge, however at the trial phase we were informed by the customer that the re set system was required even without the cylinder loaded and so we endeavoured to design a special cartridge with a higher pressure rating, this solved the customers problem.
Finally with the cylinder functioning as the customer requested we began to supply small batches. Only to discover the noise levels were unacceptable due to the customer reducing the noise level caused by the power pack. After sourcing the origin of the noise, which was a jet of oil caused by the cushioning system we designed a micro diffuser which eliminated this and therefore lowered the noise level.

Conclusion

We have now created a cylinder which through a process of rapid evolution offers customers a higher level of functionality giving them a technical and operational advantage in the market.

Crop Sprayer Hydraulic Cylinder Development

Company profile

crop-sprayer-1We have supplied equipment into the agricultural sector for 20 years and working alongside our customers have developed a range of products that provide solutions helping to resolve problems encountered on certain applications.

Opportunity

As farming has become more intensive the machinery being used has grown larger in size, this has created problems both in terms of structural stability and operator comfort, crop sprayers are one example of where our technology has helped our customers improve their products performance.

crop-sprayer-2Synchronised telescopic cylinders for boom lift and height control, these are constant velocity telescopic cylinders that also work at a constant pressure. This allows the mast to be positioned more accurately by the operator and the pressure of the accumulator pre set to create the correct cushioned effect. The telescopic method also removes the need for a more complex pulley system and reduces the maintenance in this area.
At 36 meters wide and weighing up to 1500kg the spraying boom is an awkward component to handle. The momentum that can be generated in the boom when the crop sprayer is turning is huge, causing the whole machine to jerk and imposing excessive forces through the pivot points. For this we use our double cushion cylinder acting as the main boom fold.

Conclusion

Over time this creates fatigue and eventually failure, the double cushion cylinder is designed to absorb these forces therefore the operator can sit in comfort even while turning the machine around, potential energy being generated during this operation is absorbed by the cylinder / hydraulic system so protecting the main pivot points.
