A lift device includes a lift apparatus and a base assembly. The lift apparatus is configured to raise and lower an implement assembly. The base assembly is configured to support the lift apparatus. The base assembly includes a deployable operator station transitionable between a deployed position and a stowed position. In the deployed position, the deployable operator station is configured to provide a seating and control arrangement for an operator. In the stowed position, the deployable operator station is substantially sealed from an external environment to limit access to the deployable operator station.

A hydraulic system for controlling bleed down and retraction of a boom within a safety envelope includes a backup battery power supply, and at least a first boom lift hydraulic cylinder configured to raise and lower the boom. The first boom lift hydraulic cylinder includes a solenoid bleed valve electrically connected to the backup battery power supply. The hydraulic system also includes an input device controllable by an operator of the boom. The input device may, for instance, be used by the operator to initiate bleed down and retraction of the boom from an elevated position. To accommodate independent failsafe features of the system, the input device is configured to selectively actuate the solenoid bleed valve using electrical power supplied from the backup battery power supply.

The invention relates to a method (100) of operating an actuator arrangement including at least two types of actuators (6, 7, 11, 12, 30, 34) effectuating different types of movement of a connected device (10, 32) to be actuated, where a change of attitude of the connected device (10, 32) has an influence on the position of at least a defined part (13, 14) of the connected device (10, 32). Different types of actuators (6, 7, 11, 12, 30, 34) are actuated in an automated way to at least partly compensate for the change of position of the defined part (13, 14) of the connected device (10, 32) when changing the attitude of the connected device (10, 32), at least for a certain range of movements.

A material handling system for engaging and transporting material. The material handling system includes a mouth and a hydraulic actuator for pivoting a tooth within the mouth. Once a material has been positioned within the mouth, the hydraulic piston actuates the tooth to secure the material within the mouth. The tooth is preferably configured and oriented to move into tighter engagement with the material as gravity or other forces attempt to remove the material from the mouth. The bottom jaw of the mouth tapers to a tip that allows the system to more easily pick up material from a surface and to more easily maneuver the tip into tight spaces. The hydraulic piston allows an operator to release the tooth whenever desired and a check valve provided on the hydraulic piston prevents the system from inadvertently dropping material. The material handling system includes a vehicle mounted boom coupled to the mouth so that material engaged by the mouth may be transported to another desired location.

A lift machine including a frame, a platform movable relative to the frame and structured to support a user, and a range and position determination system. The range and position determination system including a base unit coupled to the frame and structured to determine a platform position relative to the frame, a human machine interface structured to identify a desired position, and one or more processing circuits structured to: receive a total weight of the platform, determine distance and orientation information of the desired position, query a load map, return an acceptable status when the distance and orientation information and the total weight are within the operational envelope, return an unacceptable status when the distance and orientation information and the total weight are outside the operational envelope, and output the acceptable status or the unacceptable status to the human machine interface for display to the user.

The articulated self-propelled work machine (1), such as, for example, an articulated telescopic handler or the like, comprises: a front frame (11), provided with a pair of front wheels (111); a lift arm (2), adapted to support a load, hinged to the front frame (11) and mobile with respect thereto by means of at least one actuator (21, 22); a rear frame (12), provided with a pair of rear wheels (121) and articulated to the front frame (11); detecting means (51, 53, 54) for detecting an angular parameter relative to a steering angle between the front frame (11) and the rear frame (12); and electronic processing means (6) configured to control the operation of the actuator (21, 22) on the basis of the angular parameter.

A vehicle crane having a boom that can be luffed between a storage position and a working position within a vertical luffing plane by at least two luffing cylinders The luffing cylinders that lie opposite one another on the luffing plane, enclosing a spread angle between their longitudinal axes in the working position, and the luffing cylinders acting on the boom outside its ends. The longitudinal axis, projected onto the luffing plane, of one luffing cylinder and a vertical direction extending within the luffing plane enclose an angle of inclination there between when the boom is in the storage position to achieve a compact design, particularly when the boom is in the storage position.

Described is a rotary telehandler (1) comprising a carriage (10) movable on wheels, which mounts a tower (11), which in turn mounts a drivers cab (12) and an operating arm. The telehandler (1) is equipped with the following free paths of ascent and descent: a first path, defined by a first position of the tower (11), wherein it has an axis parallel to that of the carriage (10) and comprises a door (15) of the cab (12), a handle (17) on which an operator can grasp and a ladder (101, 104) made on a side wall of the carriage (10); a second path, defined by an angled position of the tower (11), wherein it is oblique or transversal to the axis of the carriage (10), with a front of the cab (12) facing towards the inside of the carriage (10), the second path comprising the door (15), a first handle (16) mounted at a first side of the door (15), a treadable surface (105, 106) of the carriage (10) and a further ladder (102, 103) made in a side of the carriage (10); and a third path, defined by a further angled position of the tower (11), wherein it is oblique or transversal to the axis of the carriage (10), with the front of the cab (12) facing towards the outside of the carriage (10), the third path comprising the door (15), a second handle (17) mounted at a second side of the door (15), a treadable surface (103, 102) of the carriage (10) and a ladder (104, 103) made in a further side of the carriage (10).

The first, second and third paths are free of obstacles for the free passage of an operator.

A working machine has a body and a load handling apparatus coupled to the body. The load handling apparatus is moveable with respect to the body by an electrically driven actuator assembly. A controller is configured to receive a tilt signal representative of a moment of tilt of the working machine and issue a control signal configured to control an electrical drive element of the electrically driven actuator assembly based on the value of the tilt signal relative to a tilt threshold.
