FIELD: agricultural and timber engineering.
SUBSTANCE: invention relates to vehicles designed for operation under limited maneuverability and heavy road conditions. Proposed trailer has frame with support wheels to which pole with two controllable hydraulic cylinders is hinge connected in horizontal plane. Points of connection of hydraulic cylinders to pole have two degrees of freedom: turning around axle and moving along curvilinear slot of pole. Piston space of hydraulic cylinders is connected with hydraulic and hydropneumatic accumulators, and rod space communicates with atmosphere.
EFFECT: improved reliability of trailer, reduced service expenses at preservation of maneuverability of trailer in confined spaces under heavy road conditions.
