Abstract:
1. A portable anchorage assembly, comprising: a counterweight assembly including a housing having a cavity configured and arranged to receive at least one weight, a rear wheel assembly having at least one rear wheel and pivotally connected to the housing, and a rear jack assembly directly interconnecting the housing and the rear wheel assembly; a base including a cross bar and at least one anchorage point, the cross bar interconnecting a first leg and a second leg; an extension member having a first end and a second end, the first end being directly pivotally connected to the housing and the second end being directly connected to the cross bar between the first leg and the second leg; a front wheel assembly having at least one front wheel and pivotally connected to the base, the front wheel assembly configured to allow the base to pivot about the counterweight assembly to position the at least one anchorage point in a desired location; a front jack assembly interconnecting the front wheel assembly and the base; wherein the rear jack assembly and the front jack assembly are adjustable in length to raise and lower the respective wheel assemblies, each of the wheel assemblies having an anchorage position and a mobile position; wherein as the rear jack assembly increases in length, the rear wheel assembly is moved downward and the housing is moved upward thus moving the at least one rear wheel downward to contact a support surface thereby moving the rear wheel assembly from the anchorage position into the mobile position, wherein moving the counterweight assembly from the anchorage position to the mobile position moves a center of gravity of the counterweight assembly from a front end of the counterweight assembly towards a rear end of the counterweight assembly to assist in moving the counterweight assembly more easily; wherein as the front jack increases in length, the front wheel assembly is moved downward and the base is moved upward thus moving the at least one front wheel downward to contact the support surface thereby moving the front wheel assembly from the anchorage position into the mobile position; and wherein as the rear jack assembly decreases in length, the rear wheel assembly is moved upward and the housing is moved downward thus moving the at least one rear wheel out of contact with the support surface and contacting the support surface with a rear portion of the housing, wherein as the rear wheel assembly is moved from the mobile position to the anchorage position, the center of gravity of the counterweight assembly moves from the rear end of the counterweight assembly toward the front end of the counterweight assembly thereby transferring weight toward the base thereby increasing a downward force on the base and making the portable anchorage assembly more stable as an anchorage structure.
