FIELD: transportation.
SUBSTANCE: trolley includes wheel pairs with the possibility of independent rotation of the wheels, side frames, rigidly connected by a horizontal frame equipped with means for suppressing hunting oscillations and a clamping brake with two pairs of holders of horizontal brake pads and with the mechanism of multidirectional transverse movement of the holders, made in the form of at least one horizontal G- or T-shaped two-arm lever on each wheel, long arm of which is pivotally connected with the traction of the car brake system, and a short shoulder – with holders, the ends of which rest on the transverse beams of the horizontal frame. Holders are supported by the transverse beams of the horizontal frame without the possibility of longitudinal movement along the trolley.
EFFECT: trolley braking system is simplified, its effect on the rolling surface of the wheels is excluded.
