A control unit for a man rider crane comprising a chassis 1 movable horizontally and an operators cab 7 movable in a vertical direction relative to the chassis 1, the control unit being a pendant control 13 adapted to depend from the roof 11 of the cab and being movable between a stowed position 14 clear of an operator and a depending operative position, the control having two manually operable control members 18, 19 operable respectively to control the positioning of the crane and the operators cab relative thereto. The control members are such that movement of the cab and/or crane is possible only when the operator moves both of the control members 18, 19 from a neutral position to which the members are resilient biassed by a torsion spring 20.
