Ribs for an elevating platform, the ribs designed and configured to insert through a slot in the sidewall of the elevating platform. The ribs are composed of T-shaped and/or L-shaped portions. Configurations include a T-shaped rib that inserts through the slot; a combination T-shaped and L-shaped rib wherein the T-shaped component inserts through the slot and the L-shaped component is attached on the exterior of the platform, and a double-L-shaped rib, wherein one of the L-shaped components inserts through the slot and the other L-shaped component is attached to it on the exterior of the platform.

A system and method using at least one inductor operatively coupled to an electrically insulating structure suppresses transient currents generated during a bond-on process by a human worker with energized electrical equipment so as to inhibit passage of the transient currents through the electrically insulating structure operatively coupled to the energized electrical equipment.

A boom lift system includes a primary conduit, a pump-motor arrangement having a motor operable to drive a pump to move a fluid through the primary conduit, first and second actuators in fluid communication with the primary conduit and actuatable in response to first and second user input to perform hydraulic function via the fluid, a valve arrangement configured to control flow of the fluid from the primary conduit to the first and second actuators, and a controller programmed to selectively actuate the valve arrangement in response to the first and second user inputs. When the controller receives both of the inputs, the valve arrangement is actuated by the controller to vary the flow rate of fluid to each of the first and second actuators. When the controller receives only one of the first input or the second input, the controller varies a flow rate output of the pump.

The control station 20 of the work platform 10 of an aerial work platform comprises: a control console; a cover 40 for protecting the console, which can be moved between a closed position and an open position; a longitudinal elementsuch as a bar 42coupled to the cover to simultaneously move between the closed and open positions, with the longitudinal element protruding from the front side of the console when the cover is open; and means for detecting an external action pushing the longitudinal element toward the console when the cover is open. This makes it possible to keep the operator safe from being crushed against the console when moving the platform. Besides, the longitudinal element is not an obstacle to the opening or closing of the cover and is put aside when the cover is closed, thus preventing same to be exposed to shocks.

A step for an elevating platform, the step including a top flange, a bottom flange, and a transition; the step configured to insert into a cutout in the platform sidewall. The bottom flange is configured to contact an outer surface of the platform sidewall when the top flange contacts an inner surface of the sidewall, thereby placing all of the contact areas between the step and the platform under compression when force is applied to the step.

A mounting rib for an elevating platform, the rib designed and configured to insert through a slot in the sidewall of the elevating platform. The rib is composed of a T-shaped and two L-shaped components, wherein the T-shaped component inserts through the slot and the L-shaped components are attached on the exterior of the platform. Also, a corner-mounted rib for an elevating platform.

Disclosed is a cherry picker (1) comprising a chassis (2), a heat engine (4), a starter (5) and a starter actuator (62) for said engine (4), a platform (8), means (9) for lifting the platform (8) that include a lifting arm (91), a control console (10) that includes a control unit (26) for the lifting means (9), a drive unit configured to control at least the arm (91) according to the data input into the control console (10), a member for powering the drive unit (11), a member (12) for activating/deactivating the control unit (26) for the lifting means (9), said member (12) being mounted to as to be movable between an inactive position, in which the control unit (9) for the lifting means (9) is deactivated, and an active position. In the working configuration, which corresponds to the raised position of the arm (91), the cherry picker (1) has an operating mode in which, when the heat engine (4) is in a stopped state while being powered, the drive unit (11) is configured to control the start of the heat engine (4) by means of the activating/deactivating member (12) without the actuator (62) for the starter (5) being actuated.

A lift device includes a chassis having a first end and an opposing second end, a first actuator coupled to the first end of the chassis, a second actuator coupled to the first end of the chassis, a third actuator coupled to the opposing second end of the chassis, a fourth actuator coupled to the opposing second end of the chassis, and a control system. The control system is configured to fluidly couple at least two of the first actuator, the second actuator, the third actuator, and the fourth actuator, and fluidly decouple and actively control the at least two of the first actuator, the second actuator, the third actuator, and the fourth actuator.

An assembly of a controller is to be arranged on a hydraulic lifting device, and a mobile control module can remotely operate the controller. Sensor data can be fed to the controller via signal inputs, and a processor of the controller is configured to calculate first information characteristic of a current position of the hydraulic lifting device from the sensor data and from specific data of the hydraulic lifting device stored in a memory. The controller has an operating mode in which parameters for a further position of the hydraulic lifting device and/or for a lifting load can be input at the mobile control module. Second information characteristic of the further position and/or the lifting load is calculated from the parameters, and the stored data is compared with the first information and/or the specific data.

An AWP boom is coupled to a platform rotator through a novel load sensing linkage system which provides both structural support and load sensing capabilities of an attached platform support structure. The load sensing linkage system includes an upper flex plate and a lower flex plate and a single load cell for load sensing capabilities. The flex plates provide for stiffness in all directions except where necessary for load sensing.
