DESIGN AND OPERATING PRINCIPLE
The PTL-F; PTL-S; PTL-P of the tractor semitrailer are metal-structure machines with a body tipping
backwards. The PTL-V of the tractor semitrailers are metal-structure machines with a glass fiber or steel tank
attached on a frame, together with centrifugal or vacuum-rotary pumps. The PTL-T of tractor trailers are metal-
structure machines with a body tipping backwards. The PTL-R of the tractor semitrailer are metal-structure
machines with a flat platform for carrying load on top of the platform. The PTL-G of the tractor semitrailers
are metal-structure machines with a box body for loading livestock, specifically PTL-G chassis are hydraulically
controlled for lifting chassis up and down.
The chassis of the semi-trailer has working pneumatic brakes with braking force regulators for each axle,
depending on the weight of the load being carried. The parking brake is controlled manually using a screw and
acts through the friction elements of the working brake of the front axle. The tractor semi-trailers are equipped
with warning signalling lights and may be used when driving by public roads.
The tractor semi-trailers are manufactured in accordance with Directive 98/37/EC and the following
normalisation provisions: LST-EN 1853:200.
4.1.
Frame
The frame consists of a thick-walled rectangular profile metal pipe welded structure, which has
mounting places for the drawbar, chassis, body, and other necessary assemblies. Ordered additionally in the
rear of a frame a hitch can be installed for pulling second semitrailer or trailer.
4.2.
Chassis
Spring chassis consists of three-leave semi-elliptical (parabolic) spring blocks, to which three axles are
mounted whose hubs have wheel mounting bolts and drum braking mechanisms with spreading brake shoes.
Each axle has two tie-rods, one of which is adjustable. The axles are aligned by adjusting the screw tie-rods.
The chassis is secured by inserting the spring blocks into the axle adjustment tie-rods and respective places at
the frame.
The rear axle hubs of the tandem chassis (front and rear axles of tridem chassis) can turn through the
alignment mechanism. When the train consisting of a tractor and semi-trailer enters a turn, the wheels of
