ABSTRACT:
A pavement patching vehicle includes an asphalt supply hopper and a distribution hopper mounted to the front of the vehicle at the end of a remotely controlled articulated arm. Asphalt is deposited into a pothole from the distribution hopper for compaction by a tamper, which is mounted to the distribution hopper by a combination tamper positioner and vibration isolator. The combination uses a specially adapted gas over hydraulic liquid in a piston and cylinder arrangement for this purpose. The articulated segments are moved through piston and cylinder drives mounted within the hollow arm segments and coupled to pivot shafts at the joints. The distribution hopper can be secured to the front of the vehicle by a support bracket on the vehicle and a pivotal support latch on the distribution hopper. An actuator bar extends from the tamper and engages a latch actuator, which extends from the support latch, when the tamper is raised. Doing so moves the latch actuator and thus rotates the support latch so the support latch engages the support bracket.
