A heavy load elevator installation platform capable of stretching and retracting steplessly, which includes an upper beam assembly and a lower beam assembly that can realize stepless stretching and retracting. The upper beam assembly includes an upper beam left C steel, upper beam middle C steel, and upper beam right C steel connected end to end in sequence. A plurality of long holes formed at an inclined included angle with the horizontal are formed in the inner side walls of each of the upper beam left C steel and the upper beam right C steel. A plurality of long holes are respectively formed in the two side surfaces, facing the upper beam left C steel and the upper beam right C steel, of the upper beam middle C steel. The structure of the lower beam assembly is the same as that of the upper beam assembly.

Systems and apparatuses include a platform charger for use with a lift, such as an aerial work platform (AWP) or mobile elevating work platform (MEWP). The platform charger includes an elevated platform, a ramp extending away from a first end of the platform, a battery, and an induction coil. The induction coil is received within the platform and positioned near an upper surface of the platform. The induction coil is configured to receive electricity from an energy source and generate a magnetic field that extends substantially upwardly, through the platform to objects positioned on the platform. The induction coil is also configured to act as an antenna, such that if the induction coil is positioned within an magnetic field, a current will be induced in the induction coil that can be used to recharge a battery associated with the platform charger.

A leveling system for a lift device includes a control system. The control system has programmed instructions to acquire operation data regarding operation of the lift device, fluidly couple a first leveling actuator and a second leveling actuator based on the operation data, acquire an update regarding the operation data, fluidly decouple the first leveling actuator and the second leveling actuator based on the update regarding the operation data, and selectively control the first leveling actuator and the second leveling actuator to (i) selectively reposition a first tractive element and a second tractive element relative to each other about a longitudinal axis defined by the lift device and (ii) selectively reposition the first tractive element and the second tractive element about a first lateral axis defined by the lift device.

The movable lifting system (1, 2) comprising a telehandler (1) which in turn comprises: a movable lifting arm (11) provided at a distal end, with a coupling device (111) for the removable fixing of equipment (112) or of the type adapted to grip loads, such as a fork, grippers or the like, or of the type suitable for lifting persons and work tools such as a basket or the like; and a powertrain assembly for movement on the ground. The system (1, 2) further comprises: control means, arranged on board the telehandler (1), provided to manage the operation of the powertrain assembly, adapted to receive command signals and adapted to regulate the operation of the assembly according to the command signals; and command means (2), separate from the telehandler (1), to be activated by an operator (3) and predisposed to produce the command signals.

A vehicle steering system for a compact mobile elevating work platform (“MEWP”) or other vehicle and a method for dynamically determining independent wheel steering angles such that a predetermined steering geometry between steerable wheels of the vehicle are described. The steering system determines coordination of the independent wheels based on angle differences of the steerable wheels. The independent master and follower wheels of the present system are not mechanically linked, and the absence of mechanical linkages between the independent steerable wheels allows for efficiency of spatial efficiency and steering geometry accuracy. The independent operation facilitates accommodation of the steering actuators into confined lateral compartments, which itself enables the machine lifting mechanism to occupy a space hitherto used for a mechanical steering connection between the wheel assemblies.

The scissor lift platform includes a frame resting on the ground by connecting members, a platform, a device for lifting the platform, including a set of jointed bars supporting the platform, so the elevation of the platform relative to the frame is variable and controlled by the set of bars, the set of bars including four lower bars defining parallel pairs hinged to four lower articulation blocks connected to the frame, the set of bars also including four upper bars defining parallel pairs hinged to four upper articulation blocks connected to the platform, and at least four sensors each measuring a reaction force, the sensors each having a lower or upper articulation block. Each articulation block/sensor includes first and a second portions. Each sensor is positioned between the first portion of the articulation block in which the sensor is mounted and the second portion of the articulation block.

A system for protecting an operator on an aerial work platform from a crushing hazard includes a sensor, such as opto-electric sensor, positionable adjacent the control panel area. A control system is programmed to control operation of the driving components based on signals from the sensor.

A fall-protection system including a harness and a fall-protection apparatus with a lifeline bearing a connector configured to be connected to the harness; and, a fall-protection monitoring system with a base unit and with at least one sensor module configured to sense a condition of the connector and to communicate a signal indicative of the condition of the connector to the base unit.
