The AGS Magnet Transporter

The transporter is in the form of a pedestal base, electrohydraulically powered to cycle automatically while moving the load in a step-like manner. The carrying capacity of this machine is 150 tons. It is designed to transport and position large magnets in the X,Y and Z axes with a precision of ±0.005". It also provides 360° rotation of the load about the Z axis with a precision of approx 90 sec of arc. Movement may be manually controlled or fully automatic at either low or relatively high speed. The unit weighs a little over 10 tons and depends for its power on one 10 hp motor that drives three pumps of a very compact hydraulic system. Carrying range of the transporter is limited only by the length of the 440V cable that supplies electric power, and by the carrying capacity of the floor on which it travels. The most progressive antifriction devices including hydrostatic oil thrust bearings, a unique 35-in. diameter hydrostatic journal bearing, air bearings and linear motion roller bearings were employed. This device is being used successfully at a BNL experimental area.
