Abstract of the Disclosure An apparatus for preventing free descent of a motor-pump unit. The motor-pump unit is mounted within a manure-containing pit for vertical sliding movement on a fixed column, and an elevating mechanism is employed for raising and lowering the pump within the pit and includes a cable having one end which is coiled on a drum while the opposite end of the cable is connected to the motor-pump unit. The weight of the motor-pump unit normally applies substantial tension to the cable. A mechanism is incorporated which is responsive to slackening of the cable and acts to arrest free descent of the motor-pump unit, as well as discontinuing operation of the cable drum mechanism.
