## Abstract

A land vehicle assembly is provided with a platform for an operator workspace. A control panel is supported upon the platform in electrical communication with the land vehicle. A caution switch is supported upon the platform in electrical communication with the control panel to provide a signal to the control panel indicative of a caution event. A cable is connected to the caution switch to extend across the control panel. The cable is spaced apart from the control panel so that a predetermined force upon the flexible member actuates the caution switch without significantly obstructing the control panel. A manual force upon the flexible member expands the operator workspace. The control panel is programmed to control a mobile operation of the land vehicle, and discontinue the mobile operation of the land vehicle in response to receipt of the caution event signal.

## Claims

### Claim 1

A mobile work platform assembly comprising:
a platform adapted to be mounted to a vehicle, sized to receive an operator thereupon;
a control panel supported upon the platform;
a caution device supported upon the platform;
a barrier member associated with the caution device to extend across the control panel and spaced apart from the control panel so that a predetermined force upon the barrier member actuates the caution device;
a socket connected to a first end of the barrier member or the platform, with a bore formed into the socket; and
a plug connected to the first end of the barrier member or the platform, sized to be received in the socket bore.
