An air motor powers an innovative transport device designed for wheeled equipment
Moving heavy rolls of paper, railway wagons, and even parked aircrafts by hand may sound like magic, but it is humanly possible! The unassuming "Easy Roller" works just as its name implies. With this device, you can easily manoeuvre up to 100 tons without exerting great effort. The secret lies within the device"s utilization of the wheeled object"s net mass to its own advantage.
Without having to climb into the driver"s cab or even turn on the engine, the mechatronics engineer can effortlessly manoeuvre the articulated lorry over the repair pit. It"s not even necessary to know how to drive one! In one hand, the engineer holds the handle of the "Easy Roller". The air motor, which powers the transport system, is hardly audible. Moreover, it does not produce any exhaust fumes, thus proving to be environmentally sound. Aside from the usual odour associated with motor oils, employees in the workshop will not be exposed to harmful emissions. Finally, there is absolutely no risk of an explosion while operating the air motor.
In a straightforward, yet ingenious manner, the "Easy Roller" acquires its power from the net mass of the wheeled equipment, and in doing so, moves forward. The transport device is positioned in front of the equipment, for example a heavy roll of cable. It operates on two rubber rollers, over which the drive roller is positioned. The front castor is pressed against the drive roller by springs. The rear section is initially comprised of free space. When the employee presses the manoeuvring valve handle, the air motor starts, thereby enabling the drive roller"s chain-controlled backward motion.
What happens? The drive roller transfers the movement to the front castor and the "Easy Roller" moves in the direction of the cable drum. Simultaneously, the device is pressed down in order to initiate contact between the drive roller and rear castor, ther
