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

Case Study : Natra Chooses Chambrelan’s Heavy Duty Slides

posted in: Case Study | 0

Natra is multinational Spanish company specialising in the confection of cocoa based products, like chocolate tablets, spreads and drinks. With manufacturing facilities in Spain, Holland, Belgium, Denmark Germany and the UK Natra is the market leader in its field with truly global reach.

In this instance one of their manufacturing plants in Belgium, which processes the chocolate before packing and sending them to market, was having problems at the end of the cycle. For as packs of chocolate spread was stacked for delivery many were being dropped as in transportation from the food line to the delivery area. This meant that the stacking machine had to be cleaned frequently and therefore would be regularly out of operation.



Natra’s engineers decided the best course of action would be to design and build a ‘Recovery Tray’, which would catch the falling jars and thereby prevent them smashing. The problem was the packs of jars, weighing 12kg each, were being dropped from a height of 1.8m and Natra knew they had to choose an incredibly strong product that would not only meet food safety standards, but would also be durable enough to take the punishing blows.

Made from reinforced steel the E1902 is a three section I-beam slide made of zinc plated steel and capable of delivering incredible extension without compromising on its load carrying capacity. At 1800mm Natra’s E1902 is capable of carrying 455kg per pair in the major axis and being incredibly corrosive resistant. A great performing heavy duty slide.

Quik Corp Fire Engineering design and manufacture a range of specialised fire and emergency equipment. By working with Queensland Rural Fire Service, the Australian Department of Defence, New South Wales National Parks, Forestry plantations and mining corporations in Australia, New Zealand, Papua New Guinea and the Phillipines, Quik Corp understand only to well the value design, experience and quality play in making their equipment.

In this particular instance Quik Corp were commissioned to design and build a Remote Fire Appliance used as an Airport Fire Appliance

Built on a 6000L MAN 6×4 chassis the Remote Fire Appliance needed to pack a stretcher mounted inside a locker complete with all the equipment for a rescue situation. The sliding locker needed to be accessible from only one side and needed to be fully extended to make access and reloading faster and easier. Extra storage was also needed for further emergency kit, but due to the height of the appliance, and to allow viewing of equipment and ease of access, Chambrelan’s slide and tilt drawer system was fitted together with the Slam Lock and handle and the draws used both Chambrelan’s heavy duty RA7R and heavy duty RA5R.

In addition further road crash rescue equipment mounted on Chambrelan RA7R 450mm closed length full extension which also incorporate Chambrelan’s Slam Lock fitted with the lock in / lock out (LILO) option.


“Being a builder of emergency equipment our paramount concern is reliability of all components we install on our vehicles. Chambrelan’s wide range of sliding systems and the companies dedication to quality, was the reason we recently changed to Chambrelan for all our heavy duty slide requirements.” Tim Syben, Quik Corp Fire Engineering.

Case Study: B & H Catering Trailers

Carl Bland has been designing and building catering trailers for over ten years and in that time has made a name for creating quality special purpose catering units.

Each unit is lovingly designed by Carl and his team to the very best standard, whilst providing a catering space capable of delivering a range of food products, including specially made burger trailers and fish and chip catering units.












First and foremost Carl needed a pair of heavy duty slides that would be able to slide out the serving counter on his trailers and chose Chambrelan’s R71 at 500mm. The R71 is a two beam heavy duty reinforced steel slide that offers partial extension and has been designed to specifically resist bucking and twisting, which can result from choosing poor quality slides or those underspecified for the job. These slides have been designed to extreme heavy loads and are ideal for vehicle applications, including high temperature environments, which again, can often damage poorly manufactured slides.

Chambrelan have made our job a lot easier.“.” Carl Bland, Managing Director B & H Catering Trailers.
