Safety system for weed destroying apparatus |
摘要 |
A weed destroying system carried on a vehicle and having electrodes for contacting weeds and a high voltage generator and a step-up transformer for supplying high voltage to the electrodes is provided with a tamper-proof safety system having redundant safety interlocks to effectively ground the vehicle and redundant safety interlocks to prevent energization of the generator until the vehicle is traveling at a predetermined speed and which de-energizes the generator if any one safety interlock is bypassed or fails in an unsafe condition, thereby requiring plural simultaneous failures to create a condition that is hazardous to the operator or to a bystander. The safety system also provides immediately-visible warning of the electrical hazard created by the apparatus and provides visual and aural indications to the operator when a safety interlock has been bypassed or is jammed closed.
