A boom lift includes a base having a first end and an opposing second end, a turntable coupled to the base, a boom coupled to the turntable, an assembly pivotably coupled to the first end of the base, and a first actuator coupled to the first end of the base and the assembly. The assembly includes a tractive element. The assembly extends from the base such that the tractive element is longitudinally offset from and spaced forward of the first end and the opposing second end of the base.

Load-handling vehicle comprising: a load-handling member, a jack (4) for lifting the load-handling member, comprising a lifting chamber (5) and a lowering chamber (6), a fluid source (7), a first fluid connection (8) from the lifting chamber (5) to the source (7), a second fluid connection (9) from the lowering chamber (6) to the source (7), the first connection (8) comprising a safety valve (10) that is open in the direction of the fluid source (7) towards the lifting chamber (5), and that is normally closed in the direction of the lifting chamber (5) towards the fluid source (7). A valve (11) arranged on the second link (9) is sensitive to the pressure of the portion of the first link (8) extending between the valve (10) and the source (7), and a unidirectional fluid circulation line (12), which can be closed according to the pressure weighing on the portion of the second fluid connection (9) between the valve (11) and the source (7), connects the first and second connections (8, 9).

The invention relates to a rolling handling machine (1) having an arm. The machine comprises an alert system comprising a memory in which are stored a plurality of alert rules for triggering at least one action from among transmitting data relating to the determined values of said parameters to a remote server (31); and emitting a visual, and/or sound, and/or vibration signal to alert the machine's driver. The triggering of an action occurs according to the speed of movement of the machine and the angular position of the arm. The invention also relates to an alert method and to a corresponding program product.

Power machines and control systems used thereon include a lift cylinder, a tilt cylinder, and a slave cylinder mechanically connected to assist the lift cylinder with raising a boom. With a lift control valve controlled to cause extension of the lift cylinder to raise the boom, pressure from a hydraulic source 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, 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.

A boom system includes a base assembly and a boom assembly. The boom assembly includes a boom including a plurality of boom sections. The plurality of boom sections includes a lower boom section coupled to and extending away from the base assembly and defining a proximal end of the boom and an upper boom section defining a distal end of the boom. The boom assembly further includes an attachment coupler assembly coupled to a boom section other than the upper boom section and configured to receive a first implement. The boom assembly further includes an implement connector positioned at the distal end of the boom, the implement connector configured to receive a second implement.

A lift vehicle includes a chassis, an implement, a lift arm coupling the implement to the chassis, a load sensor, a tilt sensor, and a controller. The lift arm includes an actuator configured to selectively extend the lift arm and a length sensor configured to provide data relating to a length of the lift arm. The load sensor can provide data relating to a load at the implement. The tilt sensor can provide data relating to an angular orientation of the chassis relative to a reference plane. The controller can receive data from the length sensor, the load sensor, and the tilt sensor. The controller can determine, based on the data from the load sensor and the tilt sensor, an operating envelope for the lift arm. The operating envelope can include a maximum extension of the lift arm. The controller can selectively limit an operation of the lift arm such that the lift arm operates within the operating envelope.

A lift device includes a base assembly, a turntable assembly, and a controller. The base assembly includes multiple base assembly batteries. The turntable assembly is rotatably coupled with the base assembly through a slip ring transmission. The turntable assembly includes multiple turntable assembly batteries. The controller is configured to operate the base assembly batteries to discharge electrical energy to the turntable batteries through the slip ring transmission. The slip ring transmission is configured to both (1) drive the turntable assembly to rotate relative to the base assembly and (2) to electrically and communicably couple electrical components of the base assembly with electrical components of the turntable assembly.

Described is a self-propelled operating machine (1) comprising a control cabin (2) for housing an operator and a unit (3) for moving a load. The control cabin (2) comprises a supporting frame (4) and a transparent wall (7) applied to the supporting frame (4) and partly delimiting the cabin (2). The transparent wall (7) can be made opaque in a controlled manner.

An apparatus includes a base frame, first and second bins, first and second hydraulic assemblies, and a computer controller. The first hydraulic assembly is configured to selectively raise and lower the first bin relative to the base frame. The second hydraulic assembly is configured to selectively raise and lower the second bin relative to the base frame. The first and second hydraulic assemblies are individually actuable, and their actuation is coordinated by the controller. In another aspect, a method for transferring product using an apparatus includes inputting to a computer controller a first threshold rate of change in weight signals of a weight sensor; relaying a plurality of weight signals from the weight sensor to the controller; calculating a determination by the controller at least in part on whether the threshold rate of change has been exceeded; and automating actuation of a hydraulic assembly based on the determination.

Described is a fork-carrier (2) for a telehandler, comprising: a frame (20) for supporting a fork equipped with an upper structure (200) comprising a gripping rod (21), which, in use, is positioned horizontally and designed to be removably attached to a coupling device (101), which is fitted to an operating arm (102) of a telehandler (10); and a lower contact element (25) designed to make contact with the rear of prongs (3) of fork; wherein the upper structure (200) is connected to the contact element (25) exclusively by means of one or more joining members (26) which are positioned inside the lateral dimensions of the supporting frame (20).
