ONEEWAY OPERATION TWOOSYSTEM OPERATION MECHANISM FOR ONEELEVER

摘要

PURPOSE:To facilitate the handing operation of a control lever to make its operation sure by constituting a two-system operation mechanism where two-system operated sources of a concrete mixer vehicle can be operated by the one-way operation of one operation lever. CONSTITUTION:U-shaped lever 28, which is rotated together with counter lever 3 and has an open groove, and slide yoke 30, which slides along slide guide 31 linked with second operation lever 1A through linkage material 21 and has long groove 35 whose axis body 33 is slided rotatably, are equipped, and spring 33 is provided between silde yoke 30 and slide guide 31. The excessive operation of the inertia force generated in first operation lever 1 is suppressed through U-shaped lever 27 by the force of spring 33 by operating rapidly second operation lever 1A, so that a mechanism where two systems are operated by the one-way operation of one lever can be obtained.
