Hydraulic Lifting/Lowering Device

Abstract: Provided is a hydraulic lifting/lowering device that can easily increase the separation distance between a coupled implement and the ground. The hydraulic lifting/lowering device 100 can execute draft control and comprises a lift arm 2, a bracket 3, a draft control lever 8, and a draft control transmission mechanism 40. The bracket 3 is provided on a rear end portion of a case 1 and rotates, using the other-end side 32 of the bracket 3 as a fulcrum, relative to the case 1 in accordance with the draft load from a coupled top link. Additionally, the bracket 3 includes attachment parts 35a-c, 36a-c that are configured to enable the attachment of a front-side end of the top link. In the lifting/lowering direction of the implement, the bracket axis Z2 is positioned higher than the lift arm axis Z1, and the attachment parts 35a-c, 36a-c, which have the axes Z3, Z4, and Z5, are positioned lower than the bracket axis Z2.
