The present invention provides an anti-entrapment device for an aerial lift having a basket or cage. The anti-entrapment device comprises an elongate housing; two or more sensors housed within said elongate housing and a switch activation device coupled to the elongate housing. At least one of said two or more sensors is positioned proximate an end of said elongate housing. Said switch activation device is arranged at an angle to the orientation of said sensor(s) positioned proximate the end of said elongate housing. The sensors are arranged to provide a detection zone and to detect obstacles within the detection zone. The sensors are configured to facilitate the alerting of an operator standing in a basket or cage to the presence of an obstacle that may potentially strike the operator before the strike occurs, and the switch activation device is configured to prevent further movement of the basket or cage once the switch activation device is activated.

Disclosed is an automatic anti-roll system and method for mobile elevator under various working conditions, related to the field of vehicle equipment. The automatic anti-roll system includes a control system, a sensing module, a driving anti-roll module, an air-operation anti-roll module and a small movement anti-roll module. The automatic response to the different manual operations to the mobile elevator is combined with automatic decision based on state sensing of the mobile elevator to realize the automatic judgment and anti-roll control for different working conditions. As a result, the active-passive combined anti-roll control can be realized for various working conditions in various complicated environments such as driving, aerial operations, and small movement. The anti-roll system has a simple structure and can be operated easily. All the advantages make this system and method meet the practical requirements of anti-roll protection for all working conditions of the mobile elevator.

A lift device includes a chassis, tractive elements, a platform, a lift assembly, a first set of proximity sensors, and a controller. The tractive elements are rotatably coupled to the chassis and support the chassis. The platform is disposed above the chassis and includes a deck for supporting an operator. The lift assembly couples the platform to the chassis and can selectably move the platform between a lowered position and a raised position. The first set of proximity sensors are coupled to the platform and detect a distance of an obstacle relative to the platform. The controller is operably coupled with an alert system and receives obstacle detection data from the first set of proximity sensors. The controller selects a subset of the first set of proximity sensors to analyze based on an active function of the lift device and determines whether the obstacle is within the minimum allowable distance.

The invention provides systems and devices for an easily replaceable bearing system for a gunner stand of a vehicle. The bearing system reduces vibration from the vehicle on the bearings, decreases wear and tear, and reduces audible rattling. The bearing system includes a shuttle having a backplate and protruding geometry. Biased members are removably attached to the protruding geometry and are configured to create tension on rails of a gunner stand, holding the bearing system within the rails.

The disclosed technology is generally directed to a lift. In one example of the technology, a lift comprises a chassis, a mounting base, a platform, a motor, a plurality of guardrails, and a counterweight. The mounting base is arranged to swivel relative to the chassis. The platform is coupled to the mounting base. The platform is arranged to slide horizontally relative to the mounting base. The motor is arranged to raise and lower the mounting base relative to the chassis. The plurality of guardrails is coupled to the platform. The counterweight is coupled to the chassis such that the counterweight prevents the lift from tipping over while the platform is extended relative to the mounting base.

A lift vehicle comprises a base, a battery arranged within the base, a drive motor powered by the battery and configured to drive a wheel, a scissor lift including a first end coupled to the base and being movable between an extended position and a retracted position, a work platform supported by a second end of the retractable lift, and a linear actuator having a lift motor. The lift motor is powered by the battery, and the linear actuator is coupled to the retractable lift so that rotation of the rotor moves the retractable lift between the extended position and the retracted position. The lift vehicle further includes an electromagnetic brake and a centrifugal brake coupled to the lift motor.

A block-type aerial work platform facilitating height adjustment includes: a moving means (10) provided as a quadrangular frame (100) equipped with rollers (101) so as to be movable to a work position; a work platform (20) on which an operator boards to perform aerial work; and a lifting/lowering means (30) foldably installed between the moving means (10) and the work platform (20) to lift/lower the work platform (20).

The aerial work platform comprises a control console (30) for moving the platform (20) to a working position at a height and for moving the chassis (2) on the ground in the forward (F.sub.AV) and backward (F.sub.AV) directions. To avoid confusing these two directions of movement because of the variable orientation of the console (30) with respect to the chassis (2), the direction of movement selected at the control console (30) is indicated to the operator by activation of at least one visual indication (63a, 64a, 64b, 70.i, 72) located on the side of the chassis (2) that corresponds to the direction of movement selected, or having a form pointing in the direction of movement (F.sub.AV, F.sub.AR) selected.
A screen (40) also indicates the direction of movement (F.sub.AV, F.sub.AR) selected by a display transposing to the screen (40) the above visual indication system in relation to the azimuthal direction of the chassis (2) with respect to the console (30).
