We produce wooden level crossing slabs made of LVL (Laminated Veneer Lumber). These slabs can be installed to both strait and curved railway tracks. Every crossing slab is individually drawn with CAD program to 3D design format according to transportation bureau instructions. Requirements are developed with the rail and traffic safety in consideration. Different rail fastenings and sleeper types are considered in the design. Glued LVL slab structures are more dimensionally stable than the nailed timber ones. LVL veneer construction is cross bonded to minimize the swelling caused by weather exposure and moisture conditions.
Transition curve, snowmobile and shift areas are also possible with this new technology. Slab length is not limited as elements can be jointed together in the direction of the track. With tongue and groove connection, for example loading areas up to 30 meters long are possible. The slab edges are grooved according to the flange rubber in use. Flange rubber is selected according to the rail weight. Approved anchoring structure is delivered with all our LVL slabs to prevent movements after installation.
The LVL level crossing is suitable for sand and asphalt roads, where traffic volumes generally stay below 2,000 cars per day. Basically, it is the only cost-efficient solution for low traffic areas like private, field and forest roads. Flange rubber is required in Finnish weather conditions for all slab types (wood, rubber and concrete). LVL level crossing slabs have already been installed in the Finnish rail network to a nearly 1,000 crossings in the past ten years.
Road winter maintenance (snow removal) should be done carefully to prevent damages to the wooden surface. Otherwise LVL is very durable without any chemical treatment. Our wooden element can be reused. If there is any need of maintenance to the rails, sleepers or support the foundation, it is possible to remove the slab by detaching the bolts and after the work is done mount it back.
We deliver level crossing with full assembly package from one location. Addition to wooden elements we also have anchoring, fastening parts, flange rubber, plywood for correct height and levelling rubbers required for concrete sleepers. We have most common parts in stock for fast delivery time.
