Fork for forklift truck, has carrier part connected to lifting device, blocking between carrier and sliding parts are energized, and engages on drive component is set into motion by drive in activated state of drive

摘要

#CMT# #/CMT# The fork has a carrier part (2) with a proximal side connected to a lifting device. A sliding part (5) is connected to the carrier part, where movement of the sliding part is blocked relative to the carrier part in an energized state. A drive between the carrier part and the sliding part lengthens and/or shortens the fork. The drive has an electric motor (8) and a transmission with a slip coupling (13). A blocking (20) between the carrier and sliding parts is energized. The blocking is engaged on a drive unit that is set into motion by the drive in an activated state of the drive. #CMT# : #/CMT# An independent claim is also included for a lifting device comprising a carrier part with a proximal side connected to the lifting device. #CMT#USE : #/CMT# Used for a lifting device e.g. forklift truck. #CMT#ADVANTAGE : #/CMT# The movement of the sliding part is blocked relative to the carrier part in the energized state, thus always blocking the fork, when the drive is not in operation or set into operation, and hence ensuring a high degree of reliability of operating the fork. The blocking between the carrier part and the sliding part is energized, and engaged on the drive unit that is set into motion by the drive in the activated state of the drive, thus effectively preventing undesired retracting and extending movement of the fork. The utilization of the slip coupling prevents the electric motor from overloading. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a representation of a fork. 2 : Carrier part 5 : Sliding part 6 : Nut 7 : Screw spindle 8 : Electric motor 13 : Slip coupling 16 : Alignment 20 : Blocking 21 : Housing 28 : Inner wall.
