Abstract
A counterweight assembly for a work machine includes a structure, support studs, a first side wall, and a second side wall. The structure is coupled to a frame of the work machine and defines through holes, a first side end, and a second side end. The support studs are coupled to the frame and correspondingly received into the through holes to support the structure against the frame. The first side wall extends from the first side end and defines a first eyelet. The second side wall extends from the second side end and defines a second eyelet. A work machine guard rail is received between the first side wall and second side wall. One or more of the first eyelet and the second eyelet receive a lifting assembly for lifting the work machine, and the support studs transfer a lifting force from the counterweight assembly to the frame.
