Abstract

The present disclosure relates generally to personnel lift vehicles that include a carriage, a telescoping lift and a load carrying frame. The telescoping lift is connected to a rear portion of the carriage and the load carrying frame is connected to and extends forward from the telescoping lift. The load carrying frame includes a bottom portion that provides an operator platform that is disposed at a central portion of the carriage between a front portion and the rear portion of the carriage. The configuration of the disclosed personnel lift vehicle provides an integral solution for counterweight requirements for the carriage while reducing the overall driving space required for the vehicle.

Claims
