Abstract
An apparatus for displacing a conveyor includes a conveyor frame which displaceably supports a conveyor belt. A first mount rigidly supports the conveyor frame as a second mount is affixed to a vehicle; the first mount being pivotably connected to the second mount at a pivot axis. A link member is pivotally connected to the first mount. An extendable device pivotally connect the link member and the second mount, the extendable device axially extends and retracts resulting in displacement of the link member. There are a plurality of extendable devices, at least some of which are located on opposed lateral sides of said pivot axis, each extendable device, when retracted, extends those extendable devices on the opposed lateral side of the pivot axis.

An apparatus for displacing a conveyor comprising:
- a conveyor frame which displaceably supports a conveyor belt;
- a first mount rigidly supporting the conveyor frame;
- a second mount affixed to a vehicle, the first mount being pivotably connected to the second mount at a pivot axis;
- a link member pivotally connected to the first mount;
- and
- extendable means, pivotally connecting the link member and the second mount, for axially extending and retracting resulting in displacement of the link member.
An apparatus for displacing a conveyor comprising:
- a conveyor frame which displaceably supports a conveyor belt;
- a first mount which rigidly supports the conveyor frame;
- a second mount affixed to a vehicle, the first mount is pivoted relative to the second mount about a vertical axis;
- an extendable element having a first end and a second end, the first end being connected to the second mount, displacement of the extendable element results in displacement of the first mount;
- a link member, connected between the second end of the extendable element and the first mount, which maintains the radial distance between the axis of the extendable element and the vertical axis constant through a wide range of displacement between the first mount and the second mount.
An apparatus for displacing a conveyor comprising:
- a conveyor frame which displaceably supports a conveyor belt;
- a first mount which rigidly supports the conveyor frame;
- a second mount affixed to a vehicle, the first mount is pivoted relative to the second mount about a vertical axis;
- a plurality of extendable elements having a first end and a second end, the first end being connected to the second mount, displacement of any axially extendable element results in displacement of the first mount;
- link means, connected between the second end of the axially extendable element and the first mount, for maintaining the torque applied to the first mount substantially constant for a given force exerted by the axially extendable element through a wide range of displacement between the first mount and the second mount.
