A method of constructing a five section telescoping aerial lift, crane or similar vehicle-mounted equipment and a lift constructed in accordance with the method having one end pivotally secured, about a horizontal axis, to the pedestal and the other end of the telescoping boom is equipped with a sheave for rigging the turret winch lift-line and/or it is equipped with a platform assembly for positioning workers, tools, or other devices at high positions, the four telescoping boom sections being extended and retracted individually by means of one hydraulic actuator for each moving section, two actuators located in the interior of the boom sections and two actuators located on the exterior of the boom sections.

A safety device for an aerial lift (10) having operator controls (23) for manoeuvring its basket (20) to a desired location and including at least one passive normally closed safety switch means (30)(130), e.g. m emergency switch, operable to cut electrical supply and prevent further movement of the basket (20), the safety device comprising a switch activation device (27,160,170) extending across the basket proximate to said controls (23) and an auxiliary safety switch (26) connected in series with the safely switch means (30,130) with its contacts C1 normally closed (switch on) unless caused to open (switch off) by operation of said switch activation means, thereby cutting off said electrical supply.

A self-contained and ready-to-use work platform attachment for mobile cranes, which transforms them into a state-of-the-art aerial boom lift with powered platform leveling and powered rotation up to 180-degrees. It can be supplied by the crane manufacturer with a new crane, or as an after-market attachment add-on, and may be easily pinned to the swing-jib mounting system on the outermost boom tip sheave head present on most mobile cranes without adaptive components or crane modification. In contrast, current work platforms and baskets only have gravity-leveling in association with 180-degrees of unrestricted platform rotation range, and current aerial lift boom trucks, which can function as crane booms, are not designed for add-on or after-market self-contained pin-on work platforms, instead having an integrally-designed platform with rotation and leveling powered from a base unit via hose and cable reels or carries, which are not required with the self-contained and ready-to-use work platform attachment.

A powered rotating and articulating self-contained jib boom of both swing jib and non-swing jib design that attaches to mobile cranes and functions as an aerial lift when fitted with an optional work platform. Since it pins onto any existing crane by attachment to a standard swing-jib mounting system using the four pinning holes and pins located on the crane's outer most boom tip sheave head, it achieves powered leveling and rotation of a platform without having to modify or add components to the existing crane. Also, with the crane jib boom hydraulically powered for rotation in the horizontal plane up to 360-degrees and articulation in a 90-degree vertical plane, an attached work platform can be kept level during up/down articulation of the crane boom in its vertical plane. Furthermore, with dielectric insulation, the jib boom, crane boom, and attached work platform are usable on live electrical line work.

A variable stackable ramp system for forming ramp assemblies for providing challenging obstacle courses including ones for aerial lift for sport jumping with skateboards, inline skates, bicycles and the like. The ramp system includes ramp modules of at least two different configurations with one being an inclined ramp module having an inclined upper riding or support surface and a straight ramp module having a generally horizontal straight upper riding or support surface. The ramp modules are adapted to be interconnected horizontally and vertically in a variety of orientations to provide ramp assemblies of selectively different overall configurations.

This is an auxiliary Tool and Material Shelf device for a use on a work platform for mobile aerial lifts. Construction and maintenance workers use the device to safely organize and position their tools and materials on the work platform. The universal configuration permits use with various sized aerial lifts and the device supports heavier material and tool loads compared to other prior art. The tool and material shelf/support device includes various options such as various shelves and material supports to be suitable for the differing needs of the user. The main components are comprised of two universal “U” shaped interlock members that fit over the platform guard rails; a vertical structural support may be custom fitted or designed complete with an adjustable locking device; and the trays and/or material supports to hold the tools and materials.

Protecting device for a user of an aerial lift and aerial lift comprising such a device

The device (100) according to the invention for protecting a user (U) of an aerial lift comprises a clothing element (100) designed to be worn by the user (U) and equipped with a signaling mechanism (101-103) connected to a controller (73) of the lift. Said alert means (101-103) comprise a member, such as a button (101) or a pull-tab, designed to be actuated by the user (U) to trigger an emergency stop when the user detects a potentially dangerous situation.

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.

The present invention is a lift accessory for aerial lifts and related machines. The lift accessory includes sets of retractable supports for materials around the perimeter of an aerial lift platform. In a preferred embodiment, two accessories would be installed on opposite ends of the lift platform. Typically, the accessory is based upon a section of steel tubing. The inside end may be pivotally attached via a bolt or other appropriate attachment means to a railing on a work platform of the lift.

An anchoring assembly for the aerial lift platform of an aerial lift vehicle, which provides a strong anchor point inside of a bucket liner for preventing an operator from being ejected from the bucket, and also provides dielectric protection mandated by OSHA and ANSI standards.

The invention discloses a hull plate paint-spraying wall climbing vehicle device carried on an aerial lift vehicle and a work method thereof, and belongs to the technical fields of naval architecture and ocean engineering and machinery automation. According to the hull plate paint-spraying wall climbing vehicle device, a wall climbing vehicle carries spraying nozzles to carry out spraying operation, so that labor intensity is lowered. A multi-spraying-nozzle spraying mode is adopted, so that the work efficiency is improved by many times, and the work period for hull plate spraying is shortened. A paint mist recovery cover mechanism adopted above the spraying nozzles can effectively suck paint mist generated in the spraying process through negative pressure, so that the toxic action of the paint mist to operators is reduced. The aerial lift vehicle is connected with the wall climbing vehicle, so that the load bearing capacity of the wall climbing vehicle is remarkably improved, the risk of accidental falling of the wall climbing vehicle can be completely eradicated, and the safety of the wall climbing vehicle during spraying operation is increased. A material supply cart integrating a stirring function, a material supply function and a paint mist recycling function is mounted on the rear portion of the aerial lift vehicle and can automatically complete the operation of paint pumping from a paint barrel, stirring, material supply and paint mist recycling, and direct contact between the operators and paint is reduced.
