Abstract

Fork spacing device (90, Fig 4, 110 Fig 5), for remotely varying the spacing between forks 20 on materials handling equipment, can be retro-fitted to a floating fork carriage 10 of the handling equipment so that, in use, device (90, Fig 4, 110, Fig 5) is fitted on top and/or behind and/or within the carriage 10. The device (90, Fig 4, 110, Fig 5) may remain in position when carriage 10 carries one of more various handling implements, and may be removably attached to carriage 10. The spacing may be varied by a reciprocating ram (98, Fig 4) or by rotary means (120, 122, 124, Fig 5), and device (90, Fig 4, 110, Fig 5) may be operated from operator's cab (6, Fig 1). Device (90, Fig 4, 110, Fig 5) may include bearer means 93, 94 for acting on forks 20, and bearer means 93, 94 may include a position compensator for maintaining the ability to vary the relative positions of the forks 20 along fork carrier means 80. Device (90, Fig 4, 110, Fig 5) may be attached to carrier means 80. Device (90, Fig 4, 110, Fig 5) may be included on a vehicle such as a telehandler (5, Fig 1). Methods of operating the device (90, Fig 4, 110, Fig 5) and fitting it to materials handling equipment are also claimed.
