PREVENTER FOR ROBBERY OF LOADS ON TRUCK

摘要

PURPOSE:To raise the reliability of a preventer for robbery of loads on a truck by a method in which the loading door of truck is protected from being left open unknowingly. CONSTITUTION:Both-side communication is made between the loader 4 of a truck 1 and a portable apparatus 10, and the receiving sensitivity of unlocking signals from the loader 4 is set up to be higher than the receiving sensitivity of unlocking signals from the portable apparatus 10. When unlocking the loading door of the truck 1 by unlocking signal from the loader 4, the unlocking signal received from the loader 4 can be exactly received by the portable apparatus 10.
