Abstract

An excavator or loader having rocker arm rolling friction-based extendable and retractable rolling stroke sections disposed in parallel, comprising a rocker arm (1), a machine body (2), and a work head (9); the rocker arm (1) comprises a front roller (3), a back roller (4), a front roller race (5), a back roller race (6), a telescopic arm (7), a telescopic support arm (8) and the like; the front roller race (5) and the back roller race (6) are disposed in parallel; the front roller (3) rolls in the front roller race (5), and the back roller (4) rolls in the back roller race (6); the front roller (3) and the back roller (4) coordinate through rolling friction to support the telescopic arm (7) to extend and retract under the rolling friction on the telescopic support arm (8); the work head (9) is connected to the telescopic arm (7); the telescopic arm (7) drives the work head (9) to extend and retract; and the telescopic support arm (8) is connected to the machine body (2). Also disclosed is a method for disposing rocker arm rolling friction-based stretchable and retractable rolling stroke sections in parallel.
