A mobile derrick includes a chassis frame and a mast frame having a rectangular front section rigidly mounted on the chassis frame. A mast is rigidly secured to the mast frame by means of a cross-beam provided at one end of the rectangular front section such that the mast extends upwardly therefrom for supporting a derrick at its upper end. A body is mounted over the chassis frame in a manner which permits it to be free from rigid connection with the mast so as to allow the mast, mast frame, and...

A vehicle for use as a mobile grandstand, having two seating members connected to a wheeled chassis, in which the seating members each comprise a plurality of rows of seats arranged with one row behind and above another row, and the seating members may be disposed either in a travelling position, in which they are positioned one above the other, and a seating position in which the seats are so disposed that they form in effect a single tier.

There is disclosed a mobile scaffolding which is powered by self contained electrical storage batteries. The electric drive is mechanically linked to the lift mechanism of the scaffolding by mechanical means comprising screw means and a mating nut means interconnected by rolling means to provide a high efficiency coupling. The lift mechanism employs very compact spring means which is biased to extend the lift mechanism from its contracted position to provide a force that supplements the electric...

A mobile crane comprises a multi-axle chassis carrying a slewing frame with a luffing jib mounted on the frame. There is also a single or multi-axle trailer having, between its axles, or above its single axle when there is only one, a device for supporting a counterweight and also for supporting the jib when the jib is in a lower travelling position. Means are provided for supporting the counterweight from the peak of the jib behind the supporting device on the trailer when the jib is in its low...

A shredder mounted on a heavy-duty carrier for shredding refuse spread on the ground such as in a land-fill dump. The shredder includes a frame structure mounted to the heavy-duty carrier, a rotating drum having a plurality of shredding elements mounted thereon, a fixed set of teeth cooperating with the rotating drum and a breaker bar assembly fixed to the shredder frame to partially cover the projected frontal area of the drum. The breaker bar assembly reduces the size of large refuse particles...

A mobile home including a doorway in the outer wall thereof communicating with a restricted, interior hallway and an outwardly swingable exterior door and an inwardly swingable interior door mounted on said outer wall for closing said doorway, the interior door including relatively foldable door sections which are precluded from folding when the inner door blocks the doorway but are relatively foldable to overlie one another when the door is swung inwardly.

A mobile multiaxle crane or similar heavy lift vehicle with pairs of lateral outriggers swiveling on vertical axes disposed on the side of the chassis is disclosed herein. These outriggers are pivotable outwardly away from the vehicle body to increase the stability thereof, and they may be swung back into the chassis profile in a unique manner for transport of the vehicle.

Methods and apparatus for implementing a Mobile IP mobile router are provided. In accordance with one aspect, the Home Agent receives a registration request packet. The registration request packet may include a care-of address for the mobile router. Networks associated with the mobile router are then identified. The Home Agent then updates a routing table to associate the identified networks with the care-of address. In addition, the Home Agent updates a mobility binding table with the care-of a...
