TRACTOR ASSEMBLY WITH SYSTEM FOR RESTRICTION OF ACCESS TO ASSEMBLY CONTROL Russian patent published in 2015 - IPC B60R25/04 F16P3/00 

FIELD: food industry.

SUBSTANCE: tractor assembly contains a frame with an internal combustion engine (ICE) and a transmission, a propelling system consisting of a wheel or a caterpillar driving gear and a suspension, a cabin with the operator's working place, working equipment, tools and drives for control of ICE, transmission and/or the working equipment, the operator's panel and a controller generating signals enabling/locking the operator's actions related to ICE launch, control of ICE, transmission and/or the working equipment or signals providing for their forced stopping. Restriction of the operator's access to the tractor assembly control is implemented not only before the beginning (before ICE launching) but also immediately in the process of the assembly working if grounds for such access restriction have occurred. Such grounds include changes in operational or natural climatic conditions or modes of the tractor assembly work, its movement outside the borders of the working area allowed for the specific operator, excess of the maximally allowed time of the operator's uninterrupted working, low activity, inadequacy or slowness of the operator actions relating to the tractor assembly control. Additional conditions for the operator to be permitted the tractor assembly control are established: presence of a permit for control of the specific tractor assembly, a tractor assembly of the specific type or drawbar category, permit for performance of the technological operations for implementation whereof such tractor assembly is accommodated, permit for control under the specific operational and/or natural climatic conditions, the operator's presence in the seat, the operator being under no effect of alcohol or drug intoxication, etc.

EFFECT: enhanced effectiveness of prevention of the operator's unsanctioned access to the tractor assembly control before beginning and in the process of work including provision for such control locking and the tractor assembly stopping in case of occurrence of such access termination grounds due to the tractor assembly working conditions and modes modification; the tractor assembly working safety enhancement.
