  • Patent number: 10815107
    Abstract: A vehicle mounted with the insulated aerial work platform includes a work platform radius limiting device which includes the lower boom inclination angle detecting sensor, and further includes the lower boom length detecting sensor, the upper boom derricking detecting sensor and the upper boom length detecting sensor, which each include an distance measuring rope and an insulated distance measuring rope retraction-and-extension measuring mechanism. The extension lengths of all of the insulated distance measuring ropes are detected in real time to calculate the actual working radius of the insulated work platform. When the actual working radius is less than the predetermined maximum working radius, the operator is allowed to perform the operational action of increasing the working radius. When the actual working radius is greater than or equal to the predetermined maximum working radius, the operator is limited from performing any the operational action related to increasing the working radius.

  • Patent number: 9777459
    Abstract: Disclosed herein is an attachment and vehicle that includes a left loader arm, a right loader arm, and a boom arm operatively attached to the left loader arm and the right loader arm. The boom arm extends in substantially the same direction that both the left loader arm and the right loader arm extends, is positioned between the left loader arm and the right loader arm, and includes a rotating mechanism at a first end for attaching and rotating a vertical column for installation in the ground. The attachment includes a first hydraulic cylinder attaching the left loader arm with the boom arm and a second hydraulic cylinder attaching the right loader arm with the boom arm. The first and second hydraulic cylinders exact rotation on the boom arm, and the first and second hydraulic cylinders extend at least substantially perpendicular to the plane of rotation of the boom arm.

  • Patent number: 9223049
    Abstract: The present application is a self-contained mobile inspection system and method and, more specifically, improved methods and systems for detecting materials concealed within a wide variety of receptacles and/or cargo containers. In particular, the present application is an improved method and system for inspecting receptacles and/or cargo containers using a single boom placed on a turntable with pivot points to allow for folding and unfolding of the boom, such that the inspection system is relatively compact in a stowed configuration and has a low center of gravity lending to greater stability.

  • Patent number: 6733227
    Abstract: Disclosed herein is an elevating lift for raising and lowering a load (such as a sensor suite) onboard a vehicle, such as a Humvee, which can allow for the transport of the vehicle in a standard transport without removal of the sensor suite from the vehicle, and can provide for a more stable support for the load than is available from a traditional mast. The elevating lift may also able to maintain the load in a parallel position as it is raised, and may be able to lock in a intermediate position where the sensor suite can be used while the vehicle is in motion.

  • Patent number: 6585079
    Abstract: A fluid-powered rotatable work platform assembly for use with a vehicle such as a vehicle having an arm for positioning the assembly. The assembly includes a work platform or support configured to support a load, a body having a cavity extending along a longitudinal axis, and an output shaft rotatably disposed within the body generally coaxial with the longitudinal axis. A linear-to-rotary force transmitting member is positioned within the cavity of the body and engaged with the body and the output shaft to translate linear motion of the force transmitting member to rotational motion of one of the output shaft and the body relative to the other.

  • Patent number: 6173810
    Abstract: A trailer personnel lift (20) with a level-sensing system (69). The level-sensing system (69) provides information to a level-indicator display (72) that indicates which outriggers (34) of the trailer personnel lift (20) need to be lowered. Upon lowering of the designated outriggers (34), the signal for the outrigger (34) changes so as to indicate that the outrigger (34) no longer needs lowering. The outriggers (34) are capable of locking into at least three positions, a first position (40A) in which the outrigger (34) extends substantially horizontal to the surface upon which the personnel lift (20) is to be located, a second position (48A) in which the outrigger (34) extends substantially vertically from the base, and a third position (46A) that is intermediate of the first and second positions, the third position being selected so that the outriggers (34) may be stabilized in the third position (46A) on an upward slope.
