Abstract (en)
[origin: US2020370269A1] A lifting arrangement for a construction machine includes a frame arrangement with a front frame portion and a rear frame portion. The lifting arrangement is mountable to the front frame portion and comprises a main arm including a pivot connector and an equipment connector and a main arm support means for pivotably supporting the pivot connector. The main arm support means is movable in a front-rear direction with respect to the frame arrangement. The equipment connector, upon pivoting the main arm between a lowered position and a lifted position, follows a substantially vertical path. The lifting arrangement comprises a tilting arrangement for tilting an equipment mounted to the equipment connector. The tilting arrangement comprises a kinematic chain for attachment to a tilting connector of the equipment mounted to the equipment connector. The kinematic chain comprises a tilting link and a connecting link pivotably connected to each other.
