Carriage for transport systems and transport system

A carriage for transport systems, comprising a frame (1) on which a plurality of wheels (2A, 2B, 2C;

• 2D) configured to run on two opposite sides (31, 32) of a guide (3), wherein the frame (1) has two frame parts (10, 11) on each of which a predetermined number of wheels (2A, 2B, 2C;
• 2D) is mounted in respective fixed and predetermined wheels positions, the frame further comprising tightening means (4) for tightening the frame parts (10, 11) to each other, the frame parts (10, 11) having respective mating surfaces (101, 111) which are pushed against each other by the tightening means (4), the tightening means providing tightening of the frame parts along a tightening direction oriented orthogonally to the mating surfaces, the wheels being mounted on the frame parts by means of respective fixed pins (PA, PB, PC;
• PD) protruding from wheels mounting surfaces (100, 110) provided by the frame parts, the wheels mounting surfaces being orthogonal to the mating surfaces (101, 111), such that the tightening direction is orthogonal to the fixed pins.
