Single Phase Hoist with Built in Automated Virtual Limits

Problem:

Customer wanted to have a hoist automatically go to three different heights based on the product coming down the line. The customer only had 110V-1-60 power being delivered to the hoists. Traditional hoists didn't have the ability to allow for programmable limit settings. The customer did not want a pendant hanging down with the parts passing by, so a radio transmitter was required.

Solution:

TSOC worked in conjunction with Magnetek and CM in order develop a solution that would meet the customer's needs. An encoder was added to the motor on the CM hoist that was capable of communicating the correct CAN language to allow for the receiver to program the virtual limits on the hoist. Because the receiver could act as a programmer, the customer didn't need to purchase an additional PLC for control. A custom transmitter was made that served as a master programmer (Flex Vue) allowing for only the maintenance supervisor access to program the receiver. The standard Flex 6EX was used in the day to day operation of the hoist. Due to the additional weight of the hoist mounted receiver, special mounting brackets and counterweights were added in order to keep the hoist balanced and operating smoothly.

End Result:

The customer was pleased to receive a high quality single phase hoist with a fully integrated and standalone programmable receiver. With an encoder, the operator was able to set 3 programmable limits anywhere in the vertical travel of the hoist. The transmitter then had a Hi, Mid, and Low button that would automatically take the hoist to the heights the customer set. In addition, the operator had the ability to jog the controls up and down with the standard up/down buttons. The ease of programming and consolidation of components made this a clean and easy solution for the customer.
