The ‘Beanstalk’, announced by the Mechanical Developments Division of William Moss & Sons, Ltd., is a one‐man operated working platform with a maximum height of 17 ft. This height allows the operator to work at positions of 22 ft. to 23 ft. from the ground. An extremely mobile equipment, it can even be pushed through an ordinary door and easily manoeuvred in confined passages and gangways. Recessed windows 9 in. back from the face of a wall can be reached comfortably while the base still provides ample stability. The requirements of the Factory Acts have been carefully considered in the design of this new equipment. The secret of this tool's performance lies in the novel use of a triple hydraulic ram and a tubular framework of sturdy construction which ‘scissors’ to permit manoeuvring through confined spaces. The actual platform is 2 ft. 3 in. square and is provided with toe boards and handrails which fold down for transit and movement under arches 6 ft. 6 in. high. A manual hydraulic pump actuated by the operator while standing on the platform gives full elevation in two minutes; descent is effected in 45 seconds. Rubber‐tyred castors provide mobility from point to point and when in operation four screw jacks give a firm foundation even on a sloping floor.
