  8. A safety system comprising an industrial vehicle and a safety device connected to the industrial vehicle and transmitting a recognition signal for a worker to the industrial vehicle, The above industrial vehicle is, A worker that performs a vertical movement; A safety bar provided in the above-mentioned work device, to which a safety hook rope combined with a safety band is connected, and to which an identification signal for the worker is input; A lift lever that outputs a signal based on the operator's manipulation of the operation of the above-mentioned work machine; and It includes a processor that controls the operation of the working machine based on the above recognition signal and the signal output from the lift lever, The above safety device is, A transponder mounted on the above safety band and outputting a recognition signal for the worker; and A safety system comprising a safety hook rope, a rope, a first hook provided at one end of the rope and detachably coupled to a safety bar provided on a work machine of an industrial vehicle, a wiring member connecting the first hook and the transponder, and a second hook provided at the other end of the rope and detachably coupled to a safety band.
  9. In Article 8, The above recognition signal is, A safety system that is output from the above transponder and input to the safety bar through the above wiring member and the above first ring.
  10. In Article 8, The above processor is, A safety system that determines whether the above recognition signal corresponds to the current worker.
  11. In Article 8, The above safety bar is, Both ends are fixed to the industrial vehicle and include a pipe, an insulating member surrounding the pipe, and a conductive member surrounding the insulating member, The above insulating member is, A safety system in which, at one end of the above safety bar, a certain width is exposed to the outside and a connector is connected to transmit a signal input to the safety bar to the processor.

Description

Industrial Vehicle and Safety System The present invention relates to a safety device for an industrial vehicle, and more specifically, to a safety device for an industrial vehicle that prevents order picking operations from being performed while the safety hook is not fastened. There is a wide variety of equipment used in order picking. Examples include conveyors, stackers, and forklifts, among which is the order picker. An order picker is a type of forklift that is a device capable of vertically raising not only the forks but also the driver's seat. An order picker is a forklift capable of vertical and horizontal movement with a small volume, and is the most widely used order picking equipment for logistics transfer equipment recently. Generally, order pickers transport cargo using a platform called a pallet; in other words, cargo is loaded onto the pallet, and the order picker lifts the pallet by inserting a fork into the pallet's tunnel. Accordingly, the fork of the order picker supports the weight of the pallet and the cargo while transporting them, and a separate fixing device, such as a pallet clamp device, can be provided to prevent the problem of the pallet detaching from the fork during transport. Conventional fastening devices required operator intervention whenever the pallet was fastened or unfastened by the fork, and a safety hook was provided as a safety device for the operator during such operations. However, conventional order picker vehicles do not determine whether a safety hook is attached during starting, driving, or operation, which allows the vehicle to be used even without the safety hook fastened; this can lead to danger when the driver uses the vehicle without fastening the safety hook.
