Telescopic Rails & Linear Guides for Emergency & Service Vehicles

Where telescopic rails and linear guides work in vehicle equipment

Typical mounting points across the industry — the tag shows which product line does the job.

Telescopic rail

Equipment trays & boards

Full-extension trays present pumps, tools and cases at working height outside the locker.

Telescopic rail

Generator & aggregate slides

Heavy-duty sets carry generators and hydraulic power packs — serviced in place, fully extended.

Telescopic rail

Van racking & drawers

Slim slides run drawer systems in service vans without stealing cargo width.

Telescopic rail

Roof & underfloor boxes

Two-way slides give access to lockers reachable from either side of the vehicle.

Telescopic rail

Municipal & defense vehicles

Slide-out battery boxes, radio racks and workbenches in special-purpose vehicles.

Linear guide

Sliding platforms & lift carriages

VX ball guides tolerate the mounting errors of a vehicle body — for sliding work platforms, lifting carriages and mast slides.

What the application demands

The engineering constraints that drive series selection — and how Veltork answers them.

vibration

Permanent vibration & shock

Rails on a vehicle live on a shaker table. VT-P's two-part construction is designed for intensive cycling, shock load and crash-test duty; preloaded executions eliminate rattle.

rainy

Weather & road salt

Open lockers see spray, salt and de-icing chemicals. Standard ISO 2081 zinc on telescopic rails can be upgraded to zinc-nickel, nickel or E-coat, with stainless balls and marine greases; linear-guide rails and carriages come hard-chromed, nickel-plated, black-oxidised or in stainless steel.

accessibility

Ergonomic one-hand access

A tray with 100 kg of equipment must come out with one hand in gloves. Ball-cage running keeps pull-out force low and constant — no stick-slip at the worst moment.

Recommended series

Start with these series; the configurators weigh your exact load, stroke and service life against the whole range.

Frequently asked questions

Are the slides suitable for crash-relevant installations?expand_more

VT-P is explicitly designed for intensive cycling, shock loads and crash-test duty. For installations that must retain equipment in a collision, we support verification against your restraint concept and supply preloaded, zero-rattle executions.

How is corrosion resistance ensured on fire and municipal vehicles?expand_more

Standard finish is zinc per ISO 2081; zinc-nickel, nickel and E-coat are available on request, plus stainless balls and marine-grade greases — specified simply as a suffix in the part number.

Can a tray be operated from both sides of the vehicle?expand_more

Yes — VT-S two-way (S2) and VT-P with the stop screw removed travel in both directions, so one tray can serve lockers opened from either side.

What load can a single equipment tray carry?expand_more

Telescopic capacities are quoted per pair of rails and reach well into four figures of kilograms depending on series, size and extension. VT-H heavy sets are configured individually — tell us the payload and locker dimensions and we return a sized set.

Do linear guides work on a vehicle body?expand_more

Yes, where equipment has to travel along a fixed axis — sliding platforms, lifting carriages, mast slides. VX ball guides in X-arrangement tolerate the mounting errors of a welded body; against corrosion, rails and carriages are available hard-chromed, nickel-plated, black-oxidised or in stainless steel.
