Abstract

A platform for overhead work, which can be raised and lowered from a vehicle or traileR, is of simple design and can be operated by the person on the platform without assistance. The working cage is supported by one or two jacks (4), and on the cage is located a control motor (2) with an operating button (1), to drive a hydraulic pump (3) by means of which the jack is operated to lift the cage. Alongside the pump is the oil reservoir tank (7), and to lower the cage, a purging valve (5) above the tank is opened, until the required level is reached.
