A restraint system for drivers of fork lift trucks with a driver's seat located in an open driver's cab includes a protective grate fastened to a protective roof of the driver's cab, which protective grate is pivotable around an axis of rotation that is located in the vicinity of the rear end of the driver's seat out of a closed position, which is approximately parallel to the driver's seat, outward into an open position. The protective grate can be fixed in the closed position. The protective grate may be retrofitted onto existing fork lift trucks, and can be operated very easily.

Restraint system

A control lever for a vehicle or a machine tool, in particular for an industrial truck, is disclosed for the generation of an electrical control signal. The actuation travel of the control lever is limited by a stop point that is defined by a stop and the control lever has means to generate a restoration force. The stop has an elastic component, as a result of which an at least slight deflection of the control lever beyond the stop point is possible. The elastic component of the stop is realized so that in the event of a deflection beyond the stop point, the restoration force, as a function of the deflection, increases to a greater extent than in the event of a deflection of the control lever between a neutral position and the stop point. When a defined, safety-critical deflection of the control lever is reached, whereby the control lever during this safety-critical deflection is moved beyond the stop, a signal can be generated by an electrical sensor, as a result of which a safety function of the vehicle or of the machine tool is actuated.

Control lever

The improvement in an industrial truck having a container, an operator station and an adjustable control valve fixed on the truck adjacent to the container comprising a control lever for the control valve mounted on a panel member pivotally mounted on the container. A rocking lever is operatively connected to the control lever and is pivotally connected to the control valve. The rocking lever is pivotally mounted on the panel member. The pivotal axis of the panel member and the pivotal axis of the rocking lever are the same so that the panel and the rocking lever can be pivoted out of an operating position wherein the control lever is within easy reach of the operator station into a service position providing access to the interior of the container on the truck.
