摘要： A telescoping boom (20) includes a boom actuator (28) having a fixed part and a movable part, the movable part configured to move along a length the fixed part, a rotary actuator ((40) operably connected to the movable part and configured to rotate relative to the movable part, a coupling pin (46) connected to and configured to rotate with the rotary actuator, and a telescoping boom having a plurality of boom sections including a base section and one or more telescoping sections configured for telescoping movement along a longitudinal boom axis relative to the base section. A rotary extension and locking system (200) is mounted on at least one telescoping section and is configured for selective coupling to the boom actuator and selective locking with a nearest outwardly adjacent boom section. The rotary extension and locking system comprises: a coupling ring (202) rotatably mounted on the telescoping section; a section pin (204) operably connected to the coupling ring; and a latch (206) configured to selectively engage the section pin. T he coupling pin engages the coupling ring in response to rotation of the rotary actuator in a first direction.

摘要： A method for controlling a crane component of a tower crane (90) in proximity of obstacles (400) at a worksite by defining a forbidden volume is disclosed. In the method a distance from the crane component to an outer surface of the forbidden volume is determined and a computing device (300) limits movement of the crane component based on the distance from the crane component to the outer surface of the forbidden volume to avoid entering the forbidden volume with the crane component while the crane is in operation. The crane component is one or more of a boom (110) and a hook block (150).

摘要： A cab support assembly supports and moves an operator's cab relative to a frame of a construction machine. The cab support assembly includes a cab support coupled to the frame of the construction machine. The operator's cab is mounted to a cab support mounting frame, which in turn is pivotably coupled to the cab support. An actuation device is coupled to the cab support and to the cab support mounting frame. The actuation device includes a first actuation device position in which the cab support frame is in a first position in which the cab support mounting frame defines a first plane, and at least a second actuation device position in which the cab support mounting frame is in a second position such that the cab support mounting frame defines a second plane that intersects the first plane at a negative angle.

摘要： A hydraulic circuit for use on a construction machine includes a first valve, a second valve, and at least a third valve. The second and third valve each includes at least one inlet port connected to a first outlet port of the first valve. The first outlet port of each of the second and third valves are configured to reduce a first pressure to a second pressure and/or a third pressure downstream of the second valve and the third valve, respectively. The second valve and the third valve also include at least a second outlet port connected to a reservoir tank. A hydraulic motor is connected to the first outlet port of the second valve, which operates the hydraulic motor in a first direction. The hydraulic motor also is connected to the first outlet port of the third valve, which operates the hydraulic motor in a second direction.
