  • Vehicle mounted boom assembly with a washer attachment
    Patent number: 10199806
    Abstract: An articulated boom assembly comprises a base and a primary boom arm extending from the base. There is a power system for actuating the primary boom arm between an extended position and a retracted position. There is an attachment operatively connected to the primary boom arm which supports a nozzle. The attachment may include an actuating mechanism for reciprocating the nozzle along the length of the attachment.

  • SELF-LEVELLING ATTACHMENT CARRIAGE FOR A BOOM ASSEMBLY
    Publication number: 20180134533
    Abstract: An attachment carriage for a hydraulic boom assembly comprises a work platform. The work platform may be a personnel basket or a fork assembly. A first actuator provides arcuate movement to the work platform about a horizontal axis. A second actuator provides rotary movement to the work platform about a vertical axis. The first actuator and the second actuator are hydraulically independent of a hydraulic system of the hydraulic boom assembly. The first actuator may be in hydraulic communication with a levelling valve. There may be means to reciprocate the work platform along the vertical axis. The first actuator and the second actuator may be integral.

  • VEHICLE MOUNTED CRANE BOOM ASSEMBLY WITH A DIELECTRIC BOOM ARM
    Publication number: 20150307337
    Abstract: A hydraulic boom assembly comprises a base and a first boom arm extending from the base. A second boom arm is pivotably coupled to the first boom arm. There is a hydraulic system for actuating the first boom arm between an extended position and a retracted position, and for pivoting the second boom arm. A work platform is coupled to the second boom arm. The work platform is provided with a brake mechanism that is independent of the hydraulic system for actuating the first boom arm and pivoting the second boom arm.
