摘要： 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.

摘要： A working machine includes a ground engaging structure, and an undercarriage supported on the ground engaging structure. The undercarriage has a drive arrangement for moving the ground engaging structure to propel the working machine, the drive arrangement comprising a prime mover and a transmission comprising a hydraulic pump arrangement configured to be driven by the prime mover. A superstructure rotatably mounted to the undercarriage and a working arm is connected to the superstructure. A first implement mount connected the undercarriage for operably mounting a working implement to the undercarriage. The undercarriage has a first actuator for raising and lowering a working implement when mounted to the first implement mount and comprises a hydraulic connector for supplying hydraulic fluid to the first actuator to actuate the first actuator, and a first auxiliary hydraulic connector is provided that is configured for supplying hydraulic fluid to an implement connected thereto.

摘要： A cover mounting bracket (16) is provided on an upper side of a left weight part (11) and a right weight part (12) constituting a counterweight (10). The cover mounting bracket (16) is formed as a U-shaped frame with the counterweight (10) side open by a left extending member (17) extending forward from the upper side of the left weight part (11), a right extending member (18) extending forward from the upper side of the right weight part (12), and a connecting member (19) connecting the front side of the left extending member (17) and the front side of the right extending member (18). A prime mover cover (28) is supported on the connecting member (19) of the cover mounting bracket (16) rotatably in a vertical direction through a hinge (31). The prime mover cover (28) is moved between an open position where an inspection opening (15) of the counterweight (10) is opened and a closed position where the inspection opening (15) is closed around the hinge (31).
