Abstract
An impact-protection canopy for use with an operator work area of a plant vehicle is provided. The impact-protection canopy includes a shelf mounted on a support assembly which is, in turn, mountable on the plant vehicle. The shelf is mounted on the support assembly such that the shelf is movable to and from an extended working position over the operator work area and a retracted stowed position clear of the operator work area. In this way, the shelf can be positioned above the operator work area to provide protection to the operator from items falling from above.
Claims24
An impact-protection canopy suitable for use with an operator work area of a plant vehicle wherein the impact-protection canopy comprises a shelf mounted on a support assembly which is in turn mountable on the plant vehicle, the shelf being mounted on the support assembly such that the shelf is movable to and from an extended working position over the operator work area and a retracted stowed position clear of the operator work area, and a hydraulic impact energy absorption assembly (IEAA) comprising a hydraulic lift cylinder connected to, and suitable for raising and lowering, the support assembly, the hydraulic lift cylinder having a head side, and wherein the hydraulic IEAA further comprises an energy absorbing means connected to the hydraulic lift cylinder.
An impact-protection canopy suitable for use with an operator work area of a plant vehicle wherein the impact-protection canopy comprises a shelf mounted on a support assembly which is in turn mountable on the plant vehicle, the shelf being mounted on the support assembly such that the shelf is movable to and from an extended working position over the operator work area and a retracted stowed position clear of the operator work area wherein the impact-protection canopy comprises a hydraulic Impact Energy Absorption Assembly (IEAA) having a hydraulic lift cylinder connected to, and suitable for raising and lowering, the support assembly, the hydraulic lift cylinder having a head side, the hydraulic IEAA further comprising an energy absorbing means connected to the hydraulic lift cylinder.
An impact-protection canopy suitable for use with an operator work area of a plant vehicle wherein the impact-protection canopy comprises a shelf mounted on a support assembly which is in turn mountable on the plant vehicle, the shelf being mounted on the support assembly such that the shelf is movable to and from an extended working position over the operator work area and a retracted stowed position clear of the operator work area wherein the impact-protection canopy comprises a hydraulic Impact Energy Absorption Assembly (IEAA) having a hydraulic lift cylinder connected to, and suitable for raising and lowering, the support assembly, the hydraulic lift cylinder having a head side, the hydraulic IEAA further comprising an energy absorbing means connected to the hydraulic lift cylinder, the energy absorbing means comprising a compartment divided by a flexible membrane into at least two chambers, a first chamber in fluid communication with the head side of the hydraulic lift cylinder and a second chamber comprising a compressible gas.
An impact-protection canopy suitable for use with an operator work area of a plant vehicle wherein the impact-protection canopy comprises a shelf mounted on a support assembly which is in turn mountable on the plant vehicle, the shelf being mounted on the support assembly such that the shelf is movable to and from an extended working position over the operator work area and a retracted stowed position clear of the operator work area wherein the shelf comprises a platform supported by at least one substantially rigid arm mounted on the support assembly, wherein the platform is deflectably coupled to the at least one arm.
