Abstract
A platform load sensing system connected between a boom and a platform includes an upper bearing link connecting the boom side to the platform side, and a lower bearing link connecting the boom side to the platform side. The upper and lower bearing links are configured to allow for relative motion between the boom side and the platform side. A load member is secured to the platform side between the upper and lower bearing links, and a load cell is secured to the boom side. A load moment on the platform side is functionally eliminated by the upper and lower bearing links, and a vertical load on the platform side is transferred through the load member to the load cell.
Claims15
A platform load sensing system connected between a boom via a boom side and a platform via a platform side, the platform load sensing system comprising:
- an upper bearing link connecting the boom side to the platform side;
- a lower bearing link connecting the boom side to the platform side, wherein the upper and lower bearing links are configured to allow for relative motion between the boom side and the platform side;
- a load member with a contact surface secured to the platform side between the upper and lower bearing links;
- and
- a load cell secured to the boom side,
- wherein a load moment on the platform side is functionally eliminated by the upper and lower bearing links, and wherein a vertical load on the platform side is transferred through the load member to the load cell.
An aerial work platform vehicle comprising:
- a vehicle base;
- at least one boom connected with the vehicle base;
- a work platform connected to the at least one boom;
- and
- a platform load sensing system connected between the at least one boom via a boom side and the work platform via a platform side, the platform load sensing system including:
- an upper bearing link connecting the boom side to the platform side,
- a lower bearing link connecting the boom side to the platform side, wherein the upper and lower bearing links are configured to allow for relative motion between the boom side and the platform side,
- a load member secured to the platform side between the upper and lower bearing links, and
- a load cell secured to the boom side,
- wherein a load moment on the platform side is functionally eliminated by the upper and lower bearing links, and wherein a vertical load on the platform side is transferred through the load member to the load cell.
