Abstract

1,217,026. Mobile swivel ladder with working platform. CARL METZ G.m.b.H. 13 Sept., 1968 [14 March, 1968], No. 43796/68. Heading E1S. A mobile swivel ladder having a telescopic ladder assembly is equipped with a pivoting bucket 5 at its free end, and means are provided to pivot the bucket as the assembly is moved vertically in order to retain the base of the bucket horizontal. A swivelling frame 7 may be provided which may be operated by one or more push rods 12 connected to a nut 10a moved along a threaded shaft by a non-reversible motor 8 driving through a reversible gear 9. Alternatively an hydraulic piston and cylinder device (Figs. 3 and 4, not shown) may be employed in conjunction with a reversible or irreversible electric motor 21, and with or without the frame 7. The motor 8 or 21 is actuated by the movement of the ladder via e.g. a gyro switch or a liquid balance. The bucket 5 is also restrained by a cable 15 with an end-plate 28 and compression spring 16, and the maximum movement can be limited by a lamp 29 operated via a contact 30 co-operating with means on the cable. The bucket can be rotated to a horizontal position when the ladder is horizontal to facilitate travel.
