Abstract
A mobile anchor tester for testing an earth anchor or a deadman or any other suitable assembly. A mobile system is provided for testing in-ground anchors, the system including a mobile platform, such as a trailer or the bed of a pickup truck having a horizontal support surface spaced above the ground. A pair of adjustable leg assemblies are provided engaging the rear end of the mobile anchor tester. The legs are adjustable, typically having hydraulic cylinders engaged therewith. The adjustable leg assemblies will extend from the back or rear end of the mobile platform to the ground. An anchor testing assembly engaged with the horizontal support surface on the mobile platform has a cable at the removed end thereof. The cable includes a hook to engage the in-ground anchor.
Claims21
A device for testing the tension bearing capabilities of in-ground anchors or the like, the device comprising:
- a wheeled, mobile platform having a generally horizontal support surface, the horizontal support surface having a removed edge, the horizontal support surface spaced above the ground, the wheeled, mobile platform having a front end, and a rear end;
- an anchor testing assembly engaging the horizontal support surface, having a cable at a removed end adapted to engage the in-ground anchor and applying tension thereto;
- a first adjustable leg assembly having a body and a leg, the body rigidly engaged with the mobile platform and spaced apart from the ground with the leg extendable and retractable therefrom, the removed end of the leg capable of reaching the ground when in an extended position and off the ground in a retracted position;
- and
- a second adjustable leg assembly having a body and a leg, the body rigidly engaged with the mobile platform and spaced apart from the ground with the leg extendable and retractable therefrom, the removed end of the leg capable of reaching the ground when in an extended position and off the ground in a retracted position.
A device for testing the tension bearing capabilities of in-ground anchors or the like, the device comprising:
- a wheeled, mobile platform having a generally horizontal support surface having a removed edge spaced above the ground, the wheeled, mobile platform having a front end, and a rear end;
- an anchor testing assembly engaging the horizontal support surface, having a cable at a removed end adapted to engage the in-ground anchor and applying tension thereto;
- a first adjustable leg assembly having a body and a leg, the body rigidly engaged with the mobile platform with the leg extendable and retractable therefrom, the removed end of the leg capable of reaching the ground when in an extended position;
- a second adjustable leg assembly having a body and a leg, the body rigidly engaged with the mobile platform with the leg extendable and retractable therefrom, the removed end of the leg capable of reaching the ground when in an extended position;
- wherein the mobile platform either is a truck or a trailer;
- wherein the anchor testing assembly includes a first hydraulic cylinder adapted to apply tension to the cable;
- and wherein the first and second adjustable leassemblies comprise second and third hydraulic cylinders;
- and further including means to selectively apply hydraulic force to the hydraulic cylinders;
- wherein the anchor testing assembly includes a frame configured to lay adjacent and on top of the horizontal support surface of the mobile platform, the frame pivotally attached at a near end thereof to the horizontal support surface of the mobile platform, the frame adapted to secure the first cylinder thereto, wherein the first cylinder comprises a barrel and a rod, and wherein the cable is attached to the removed end of the rod;
- wherein the frame further includes a pulley for engaging the removed end thereof, the pulley for entraining thereon, the cable;
- wherein the frame is engaged with a fourth hydraulic cylinder, the fourth hydraulic cylinder for further engaging the horizontal support surface and the frame such that the removed end of the frame moves in an arc, the arc in a plane generally parallel to the horizontal support surface;
- and
- wherein all the hydraulic cylinders are double-acting hydraulic cylinders.
