Abstract 1,100,477. Masted lift trucks. LANSING BAGNALL Ltd. 31 May, 1966 [3 June, 1965], No. 23769/65. Heading B8H. In a masted lift truck, a reach carriage is movable along horizontal guides 22, 23, which are connected by a turntable mounting to a bracket on the lifting carriage, by a pair of driven endless chains 43 the arrangement being such that the connections between links 49, pivoted to the reach carriage, and the chains pass part of the way around the end sprockets at the limits of movement of the reach carriage whereby the speed of the carriage is reduced as it approaches the limits. In the embodiment shown, the reach carriage comprises a section 29, supporting the fork arms 32 and pivoted to the links 49, and a section 28 suspended from a trolley running in the guides 22, 23 and connected by a scissor linkage 33, 37, 38 to the section 29. The turntable mounting and the endless chains are driven by electric motors and limit switches are provided at the limits of travel of the endless chains. In a modification (not shown) the links 49 are pivoted to the section 28 of the reach carriage and hydraulic rams are provided to expand and contract the scissor linkage. In a further embodiment (not shown), the scissor linkage is replaced by a rigid link.
