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.
Special cases
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.
When wood?
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.
Maintenance
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.
Delivery
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.
