摘要:
A trolley 10 can be moved between a raised position and a lowered position. The trolley is usually in the lowered position when it is put into an ambulance. A magnet 252 is secured to one connecting leg of the trolley and a counter 258 is connected to the top frame 16 of the trolley. When the trolley is moved to a lower position the magnet 252 comes in close proximity to the counter 258 and a count is recorded. The recorded count gives an indication of the number of times that the trolley has been raised and lowered.
