3. INTENDED USE AND CONSTRUCTION
The PSV and PSV Up (H) plows are a medium duty plow intended for use on roads, car
parks, lots which are slightly uneven or similar jobs. These can cooperate with both tractors and
other self-propelled vehicles (e.g. telescopic loader, excavator/loader etc.). PSV Up (H) Snow
Plows cooperate with any popular trucks and tractor equipped with front linkage in conformity with
PN-EN 15432 (DIN76060).
3.1. PSV plows
Thoroughly tested construction and the right choice of materials ensure a high reliability and
durability of our products. Thoroughly tested construction and the right choice of materials ensure
a high reliability and durability of our products. The PSV snow plow basically consists of a
suspension system (B) with a replaceable mount (A) and adjustable right (C) and left (D) operating
systems adjusted through the use of hydraulic actuators (G). Dual directional actuators are
controlled using the tractor's hydraulic system with a controllable directional valve. More detailed
construction of the plow has been presented on Fig. 3.

The PSV, PSV Up (H) plows are medium duty plows which are capable of withstanding
snow pressure of up to 6 tons. A schematic of permissible load distribution has been presented in
Tab. 4 positions a), b) and c). These plows often operate on uneven terrain and are subject to
meeting immovable obstacles which the operator often can not see, especially when covered by
snow. For this reason the PSV plows have been equipped with a number of overload safeguards:
 the first is the lateral coping system, which allows for overcoming slight diagonal bumps by
adjusting to them. Plow construction allows the plowshare to tilt right or left by 6° in relation to
the mount (Fig. 21),

 the second are the side bumpers which protect the plow from side collisions with for example
a curb (Fig. 3 “K”, Fig. 4 “J”),
 the third optional system are the folding blades - after encountering an obstacle the fold back by
35° allowing the plow to easily overcome these obstacles. The folding mechanism of the blade
with new rubber inserts allows the plow to drive over 12 cm curbs. It should be remembered
however that if the rubber insert becomes worn and is shorter by, for example 5 cm – this plow
can only drive over a curb 5 cm lower. If the user plows in an area where high curbs are present
he should change the rubber inserts more often.
Tab. 3. The working of the blade
This concerns 1 blade. PSV 301 – 4 blades, all others PSV – 2 blades
