A munitions handling vehicle is adapted for loading and unloading weapons in military aircraft. The munitions handling vehicle includes a vehicle chassis and a plurality of wheel axles attached to the chassis. A plurality of omni wheels are mounted on respective wheel axles, and cooperate to induce omni-directional movement of the vehicle. A mechanical lift is supported by the vehicle chassis. A munitions carrier is secured to a top end of the lift, and is movable upon actuation of the lift between a weapons-transport position and an aircraft-access position. In the weapons-transport position, the lift is sufficiently retracted adjacent the vehicle chassis to facilitate transport of weapons in the carrier to and from the aircraft. In the aircraft-access position, the lift is sufficiently extended to enable precision loading and unloading of weapons in the aircraft without repositioning or reconfiguring the aircraft.

A telescoping mast apparatus has a plurality of nesting cylinders. The telescoping mast apparatus has a plurality of telescoping cylinders and a plurality of straps. The plurality of cylinders is extendable from a base. Each strap extends from near a bottom of an outer cylinder, around an upper roller near a top of the outer cylinder, and is attached near a bottom of an inner cylinder. The plurality of straps and the plurality of telescoping cylinders intercouples in series with alternating straps and cylinders. The plurality of cylinders is extended by retracting a first strap from the outer cylinder, which raises an intermediate cylinder, which retracts the intermediate strap from the intermediate cylinder, which raises the second intermediate cylinder.

The invention discloses a mechanical lifting device convenient to fold. The mechanical lifting device comprises a base and a lifting plate. Two plummer blocks are fixedly connected with the upper surface of the base and are arranged symmetrically. Threaded rods are fixedly connected with the inner walls of the two plummer blocks correspondingly. A double-shaft motor is fixedly connected with the upper surface of the base and located between the two threaded rods. The two output ends of the double-shaft motor are fixedly connected with one ends of the two threaded rods through couplings correspondingly. According to the mechanical lifting device, the two threaded rods are driven to rotate through operation of the double-shaft motor, thus, two threaded sleeves move relatively on the two threaded rods, when the two threaded sleeves move relatively, the included angle between two connecting rods is changed, then the lifting height of the lifting plate is changed, in addition, when the mechanical lifting device is not used, the two threaded sleeves move away from each other through operation of the double-shaft motor, the height of the lifting plate is decreased to the minimum, and theoccupied space in the vertical direction is greatly decreased.

A maintenance vehicle for performing operations along an aerial ropeway of a mechanical lift installation consists of a car (13) suspended on the rope by a connecting means which comprises a top part (14) fixed to the rope, a bottom part (15) fixed to the car (13), an articulation means of the top part (14) with respect to the bottom part (15), adjustment means (23, 24, 25, 29) of the angle between the bottom part (15) and top part (14) up to an inclined position of the car (13) with respect to the vertical, and means for securing car (13) in the inclined position.

A long-term storage facility has an array of storage packages receiving respective cases containing radioactive materials. Each storage package has a lateral body delimiting a housing for receiving a case, the package body being closed at its top end and at its low end respectively by a removable head cover, and by a package base. The package base has a removable base cover, allowing insertion of the case via the low end of the body. The packages can be moved inside the facility by a mechanical lift. The facility includes a pivoting frame for swinging a storage package from a horizontal orientation in which the storage package is loaded to a vertical position in which the storage package is stored.

Reed's High-Rise Emergency Rescue Egress System, a conventional truck chassis fitted with a hydraulic lift system for access into and the evacuation of individuals from high-rise buildings. The technology is comprised of the following components: A control room located behind the cab of the truck, which is used to operate the lift system, monitor system operations, detect chemical, radiological, biological or other hazardous agents, and provides communication support; an gondola cabins which provides protection while transporting personnel and equipment up and down. The gondola has the ability to be connected to a building's internal / external water stand-pipe system to allow hoses to be used directly from the cabin and an audio / video monitoring system that transmits information to the control room; a mechanical lift system, which utilizes hydraulic and electrical lifts. The lift system is powered by the vehicle's motor. The lift system is augmented by an electrical / hydraulic turntable frame that maneuvers a platform containing the gondola cabin and allows for the gondola cabin to be extended and retracted, raised and lowered. Additionally, buildings can have an optional fixed or portable cantilever system that also aids in the movement of the cabin. The ground rescue vehicle and the roof cantilever system may move vertically simultaneously.
