The purpose of this study is to examine whether the work equipment of a 1-ton LPG truck-based aerial work platform can be electrified while keeping the added weight minimal under the chassis permissible gross weight. To this end, an electro-hydraulic system powered by two on-board 12 V lead-acid batteries in parallel was built, and repeated motion tests on the vehicle were used to examine its applicability and to compare the electrical and hydraulic characteristics of representative motions. The system consists of a stand-alone hydraulic pack in which a brushed DC series-wound motor drives a fixed-displacement gear pump directly and the delivery passes through a pressure-compensated directional valve to the boom actuators. Battery terminal voltage, battery output current and hydraulic pressure were sampled at 10 ms intervals. The six boom motions were repeated within a test set and three sets were carried out, giving 96 motions performed without interruption, with the platform unloaded and the engine idling so that charging proceeded in parallel. In every motion the sequence of electrical start-up, pressure build-up and steady operation was the same, and hydraulic pressure developed normally in all motions. The starting-current peak recurred at the same level irrespective of the motion, while the steady-state current stayed at a similar level within each motion. Applicability was confirmed, while the power capacity and the starting peak current remain to be resolved. Reducing them requires raising the system voltage, which must be weighed against the resulting loss of working height.
