           1. The transport packages adopt nude packing, cartoon case and wooden pallet.
           2. There are many parameters needed into consideration including rated capacity, model, power supply, standard lift, standard pendant drop, hoisting speed, motor output, chain diameter, number of chain falls, rating, control voltage, power cord length, weight and other specifications.
           3. The electric chain hoist vary from 1ton-5tonne are available in 3 phase single speed, 3 phase dual speed and 1 phase single speed.
           4. Operation of the detection unit  built into the reduction gear shuts off the hoists operation circuit. This is Ramhoist’s unique “overload prevention unit” which detects overload operation and then stops operation while keeping the load hoisted.
           6. Caution
           ①The wheel stopper is always installed on the end of the travel rail to prevent the trolley from dropping off after the trolley has been installed on the travel rail. Remember to avoid using the stopper to stop the trolley by letting it run into the stopper.
           ②Using a stopper that is a different color from the travel rail is an effective means for preventing the trolley from striking the stopper because it makes the stopper stand out.
