摘要
The support is for the travel chassis of a jib crane, esp. a rail-mounted one. One each side of the chassis are two outriggers (32) slewing on vertical axes (31). Each has a mounting plate (38a) at the forward end, to support either a screw jack or a travel wheel (47). The plate can be rectangular, with holes at the corners accommodating screws to secure the jack or the wheel bracket.
