摘要： Disclosed embodiments include power machines (100; 200; 400; 500) with a lower implement (434; 534; 334) pivotally coupled to an undercarriage frame (212; 412; 512) by a lower lift arm structure (430; 530) and which include one or more cylinders or actuators (432-1; 432-2; 532) that are operable to pivot the lower lift arm structure and lower implement relative to the undercarriage frame. A configuration of the one or more cylinders which mounts the cylinders behind the lower implement, with attachments to the undercarriage and to the lower lift arm structure at positions which allow the cylinders to be surrounded and protected by the undercarriage, reduces damage to the cylinders during operation.

摘要： Disclosed embodiments are directed to quad track skid-steer loaders and power machines having a frame (110, 210, 310), a cab (250), and a lift arm assembly (230, 330) pivotally coupled to the frame rearward of at least a portion of the cab and extending forward of the frame. A first axle assembly (227A, 327 A, 427 A) and a second axle assembly (227B, 327B, 427B) on a first side of the frame mount first and second track assemblies (419A, 419B). A third axle assembly (227C, 327C, 428C) and a fourth axle assembly (227D, 327D, 427D) on a second side of the frame mount third and fourth track assemblies (419C, 419D). A first drive motor (226A) rotates the first and second axles to drive the first and second track assemblies and a second drive motor (226B) rotates the third and fourth axles to drive the third and fourth track assemblies.

摘要： Disclosed embodiments include power machines (100; 200; 300), control systems (400; 450; 500) for power machines, and methods of controlling a power machine to automatically couple an implement (305) to an implement carrier (272; 370) of the power machine. Sensors (452) are used to identify positions of a power machine and of an implement, such as a bucket, to be coupled to the implement carrier of the power machine. Control methods are implemented to allow the power machine to be automatically controlled to couple the implement to the implement.

摘要： Disclosed are front entry cabs (250; 350; 550; 650), and power machines with front entry cabs, having a door (324; 524; 624) that is moveable between opened and closed positions. In the opened position, the door is positioned within an operator compartment of the cab above the operator seat (364; 564; 664) and below a top of the cab. A linkage system (330; 540; 640) defines the travel path of the door between closed and opened positions. The linkage system is configured to minimize interference with operator visibility.

摘要： Power machines (100; 200; 400) such as excavators with control inputs (466; 468) that are configurable to control various functions on the excavator. In some modes, selected control inputs are manipulable to control the position of a lift arm (230), bucket, and house (211) position. In other modes, the same control inputs are used to control travel and an implement (334) on an undercarriage (212).

摘要： Power machines (100; 200; 300) with implement carriers (170; 270; 370; 400; 400-1) that can sense the proximity of an implement (456) to the implement carrier with a plurality of sensors (424; 426). Such sensing is indicative of the likelihood of an implement being positioned adjacent to the implement carrier. In some embodiments, a sensor (466; 474; 476) detects whether a locking mechanism is activated.

摘要： A first work tool arm (250) is rotatably attached to a frame (223) or reference structure, a second work tool arm (260) rotatably attached to the first work tool arm, and a work tool (265) attached to an end of the second work tool arm. An actuator (226) and a spring (270) are each rotatably attached to the second work tool arm and configured such that separate movement of the first work tool arm relative to the frame or reference structure and movement of the second work tool arm and work tool relative to the first work tool arm are achieved with actuation of the actuator.

摘要： Power machines (300) and control systems (360, 400) used thereon include a lift cylinder (333), a tilt cylinder (335), and a slave cylinder (337) mechanically connected to assist the lift cylinder with raising a boom (330). With a lift control valve (405) controlled to cause extension of the lift cylinder to raise the boom, pressure from a hydraulic source (362) is provided to the slave cylinder to aid in raising the boom. Resulting increased pressure on a side of the slave cylinder opens load holding valves (370, 460), allowing hydraulic pressure from the tilt cylinder to be communicated to the slave cylinder such that tilt cylinder pressure due to a heavy load on an implement aids in raising the boom.
摘要翻译：其上使用的动力机械（300）和控制系统（360,400）包括机械连接的提升缸（333），倾斜缸（335）和从动缸（337）以协助提升起重臂（330）提升油缸。在提升控制阀（405）被控制以使提升油缸伸展以提升动臂的情况下，来自液压源（362）的压力被提供给从动油缸以帮助提升动臂。在从动缸的一侧上产生的增加的压力打开负载保持阀（370,460），允许来自倾斜缸的液压压力传递到从动缸，使得由于工具上的重负载引起的倾斜缸压力有助于提高繁荣。
