IN many hoist operations, for example, lifting racks of tobacco into a curing barn, a single operator tries to guide the load to the proper height and position it while controlling the motion by means of a switch on a multiconductor cable which is apt to get tangled with the lift chain and load. A simple wireless controller has been developed which gives precision height control, eliminates the control cable and allows the operator to stand clear of the chain and load. The controller consists of a 310 MHz hand-held transmitter which transmits a separate code depending on which of three function switches is pressed (up, down, stop). Codes are received and fed into a series of three decoders; one for each of the three codes transmitted. One of the decoders will recognize the signal and actuate the appropriate switch in the hoist. Modifications made in the hoist control circuit consisted of the addition of a switch driven laterally by a ball nut and shaft and a series of three trip blocks to stop the hoist at any one of three preselected heights. All of the original capabilities of the hoist were retained. The wireless controller performed according to design expectations and lift height precision was within about 3 mm (1/8 in.).
