A land vehicle assembly is provided with a platform for an operator workspace. A control panel is supported upon the platform in electrical communication with the land vehicle. A caution switch is supported upon the platform in electrical communication with the control panel to provide a signal to the control panel indicative of a caution event. A cable is connected to the caution switch to extend across the control panel. The cable is spaced apart from the control panel so that a predetermined force upon the flexible member actuates the caution switch without significantly obstructing the control panel. A manual force upon the flexible member expands the operator workspace. The control panel is programmed to control a mobile operation of the land vehicle, and discontinue the mobile operation of the land vehicle in response to receipt of the caution event signal.

The aerial lift platform includes a control station, a floor including a positioning zone for an operator maneuvering the control station, and a railing. The platform includes a protection device located on a surface of the railing. The zone and the protection device each extend on either side of a plane perpendicular to the first surface of the railing. A width of the protection device, measured perpendicular to the plane, is larger than 30 cm. The protection device is movable between: a retracted position, in which a protrusion height of the protection device relative to the railing, measured perpendicular to the floor, has a value below 10 cm, and a protection position, in which the protrusion height has a value above 30 cm. The railing includes an opening for accessing the platform, which can be at least partially obstructed by closing elements.

Embodiments of a personnel basket for attachment to a crane boom include folding sidewall sections; a rear wall connected to the sidewall sections; a front wall in pivotal connection to one of the folding sidewall sections; a floor in pivotal relation to the rear wall; a stalk integral to the rear wall and including a boom connection; and a cam or stop that transmits floor loads to the stalk. Because of the pivotal relationships, the personnel basket is moveable or foldable in a connected or assembled condition between a deployed (unfolded) state and a folded (fully collapsed) state. When in the deployed and folded states, the walls and floor remain connected to the personnel basket, the walls sharing a same orientation, the floor pivoting toward and away from the rear wall between a horizontal and vertical orientation.

A quick coupling implement for an aerial device has a base, a boom assembly, the implement, and an adapter. The adapter is emplaced on a portion of the boom assembly to allow for quickly coupling the implement. The adapter comprises a boom-raise-interfacing segment with at least one opening for securing to the boom raise of the boom assembly via a retaining pin. The adapter also comprises an implement-interfacing segment that presents a complementary shape to an adapter-receptor segment of the implement. The implement may be a utility platform for supporting a utility worker.

A boom assembly includes a first boom, a second boom pivotally coupled to the first boom, and an actuator assembly having (i) a first end coupled to at least one of the first boom or the second boom and (ii) an opposing second end coupled to the second boom. The actuator assembly includes a first actuator, a second actuator flexibly joined to the first actuator at the opposing second end of the actuator assembly, and a rigid coupler positioned to fixedly couple the first actuator and the second actuator together at the first end of the actuator assembly. The rigid coupler is configured to pivotally couple the first end of the actuator assembly to the at least one of the first boom or the second boom. The first actuator and the second actuator are configured to move relative to one another in response to various loading conditions.

A base unit for a lifting vehicle includes a chassis having a chassis plane and a plurality of wheels, each of the wheels being mounted on the chassis by a suspension mechanism having a suspension element and a suspension actuator that controls the position of the suspension element relative to the chassis. The suspension element is arranged to pivot relative to the chassis about an inclined pivot axis in response to actuation of the suspension actuator.

A land vehicle, is provided with a mobile work platform assembly with a platform mounted to the land vehicle, sized to receive an operator thereupon. A frame extends from the platform. A positioner assembly includes a guide mounted on the frame of the mobile work platform assembly. A carriage is provided on the guide for translation along the guide. Hardware is provided on the carriage to support a workpiece upon the carriage external of a perimeter of the frame. The carriage includes a brake assembly to position the carriage at various positions along the guide.

A horizontally articulating platform arm is described. The horizontally articulating platform arm includes a horizontally articulating arm and a rotation limiter. A proximal end of the horizontally articulating arm is configured to be pivotably secured to a boom assembly, and a distal end of the horizontally articulating arm is configured to be pivotably secured to a utility platform assembly. The horizontally articulating arm is configured to be emplaced in an aligned configuration. A first angle is deviated from the aligned configuration between the proximal end and the boom assembly, and a second angle is deviated from the aligned configured between the distal end and the utility platform assembly. The rotation limiter assembly is configured to mechanically prevent a summation of the first angle and the second angle from exceeding a maximum total angle, which may be associated with the utility platform assembly striking the boom assembly or other components.

Devices for controlling movement of aerial buckets via hydraulic systems. Each hydraulic system has valves that control movement of the aerial bucket. A control head of the device has a joystick that is moveable and encoders that detect movement of the joystick. A valve actuator manifold of the device is coupled between the control head and the hydraulic system and supports valve actuators moveably coupled to the valves. Servo drive systems supported by the valve actuator manifold are coupled to the valve actuators and are controllable to move the valve actuators. A processor module of the device is in communication with the encoders and the servo drive systems. The processor module controls the servo drive systems based on input from the encoders such that moving the joystick controls movement of the aerial bucket.

A vehicle and a hydraulic propulsion system for the vehicle are provided with first and second motors diagonally arranged relative to one another on the vehicle, and third and fourth motors diagonally arranged relative to one another on the vehicle. First, second and third flow divider combiner assemblies are provided and are arranged in a closed fluid loop with the motors. A first port of each of the assemblies are fluidly connected to one another. The first assembly has a second port fluidly coupled to the first and second motors, and a third port fluidly coupled to the third and fourth motors. The second assembly has second and third ports fluidly coupled to the first and third motors, respectively. The third assembly has second and third ports fluidly coupled to the second and fourth motors, respectively. A method of controlling the hydraulic system is also provided.
