These low profile "plug in" battery operated electric power packs slip under trolleys, beds etc. to provide a quiet simple and easy way of moving wheeled appliances that might otherwise cause strain and injury because of the weight. They are ideal, for carpeted and sloping areas. Because they fit neatly up against what they are attached to they take up little room. A bonus if you are moving goods in elevators & tight areas. We supply special fittings and adaptors for all of the different applications. The standard format is with a vertical console with twist grip or lever grip controls. Optionally available with tiller steering and lever grip controls. It is supplied standard with a "back off reversing bar or button" that prevents an operator being jammed against an obstruction. When activated, it automatically reverses the direction of travel away from the operator for a few seconds. An "emergency stop button" on the console to immediately cut the power when it is actuated. A "battery condition monitor" indicates the charge level in the battery.
