Chambrelan Launches the D5 Aluminium Telescopic Slide

posted in: Lead Story | 0

Chambrelan_D5Next to the RA7R, the RA5R is one of our most popular heavy-duty telescopic slides in the Chambrelan range.   Up until now the RA5R, which is the standard carbon steel product and the ST508, the stainless steel version, have been the only two products in the RA5 collection.  Over the years both have been modified by improving the deflection criteria, which increases the stated load capacities, but with news of the D5 launching on the market Chambrelan have finally managed to complete the range offering the same profile in three different materials.

The new D5 anodised aluminium slide is 50% lighter than the standard RA5R, making it a positive addition to the collection and ideal for electronic applications, cash dispensers and control boards.

The new addition is just another example of how Chambrelan aims at extending and improving its entire range, offering a broader and more versatile collection of heavy duty sliding systems.

Case Study: LNER

chambrelan-linear-rail-LNER011-300x219Carriage 70759 has had an interesting history, built in York in 1943 to aid the war effort as a Pigeon Van (big business for the Railways until 1966) it is a gangwayed bogie carriage of standard Gresley outline and made to full passenger specifications used to convey baskets of carrier pigeons to the point of release, as well as general parcel traffic.

chambrelan-linear-rail-LNER02-300x221This teak bodied carriage remained in traffic until 1971, when it, along with two others, were sold to a book publisher as storage units. Unfortunately the sale did not go well for having completed the sale, British Rail promptly lost the carriages. The day, however, was saved by a group of Rail Enthusiasts who managed to track down the carriages to York marshalling yard, where one of them had been commandeered as a mess room for the yard-men. The marshalling Yard master was not so willing to relinquish them saying they’d be a riot were the publishing company to try to take their mess room away. So the situation was left a month while the men made alternate arrangements and the coach returned to its rightful owners. Having changed hands a number of times ownership then passed to the Severn Valley Railway Charitable Trust, on whose behalf the LNER carriage Group are refurbishing it.

chambrelan-linear-rail-LNER03-300x223At one end of the carriage is a luggage van, complete with fold down shelves which would have carried the pigeons, as well as a guard’s brake compartment and a W.C. A side corridor, (70759 was one of the later corridor coaches, built 1943, on the British Main-line) allow access to the passenger compartments which house the sliding doors, the original designs of which were created at the tail end of the Victorian Period, between 1896 and 1898 and were not updated until 1950.

Having survived the war, racing pigeons, a grumpy yard master and years of passenger wear and tear the six foot doors began to show their age and so Chambrelan were called to fit a run of linear rails which would allow the doors to be supported along the full length of travel.

The doors design in 1898, (one of which has been in use since 1912), needed support along the full length of travel since they were very tall, but the original design meant the door was only being supported half way along and since the doors are extremely heavy they projected over the end of the runners, which faced daily wear and tear.

Having discussed the project at length Chambrelan suggested the E46 linear rail and the G54 carrier, capable of carrying 310kg in the major axis. The doors were so heavy they needed two carriers on each rail, allowing the door to slide along the full length of the travel.

 

 

 

“Chambrelan have been extremely helpful. As soon I called Jeremy he came straight over and we decided there and then. The great improvement over the original is the continuous full length support.” Richard Gunning, LNER Project Manager

Product Review: RA7R Heavy Duty Slides

posted in: Product Review | 0

Chambrelan_D5With a load capacity of up to 350kg per pair and protected by a tough white zinc plate the RA7R is one of the best performers of Chambrelan’s range of heavy duty slides.

Favoured by vehicle builders the RA7R is a three beam heavy duty steel slide employing the use of precision steel ball-bearings which not only makes for a smoother performance, but also adds structural support by spreading the mass of supported loads.

Some years ago Chambrelan upgraded the designs of their heavy duty slide range with the unique inclusion of reinforced bearings that guard against and offer greater resistance to lateral or side loadings.  This upgrade uniquely enables our telescopic slides to be used in both the major or minor axis when the slide beams are compressed against each other by the applied load.

Further upgrades to the RA7R heavy duty slide include the option of sequential movement, which cleverly coordinates the travel of each beam in turn, extending and retracting the slide beams in a set sequence, meaning a reduction in operating forces especially noticeable when the slides are carrying extreme loads.  These sequential heavy duty slides are ideal for manufacturing lines, battery storage boxes and industrial generators that need access for maintenance and repairs.

As one of Chambrelan’s most popular heavy duty slides Chambrelan UK have ensured there is ample stock available for UK and Australian customers.
