  11. 11 . The apparatus of claim 6 , further comprising a drive shaft guide operatively associated with the telescopic arm for aligning the drive shaft relative to the at least one clamping assembly, when the clamping assembly retracts relative to the drive mount via the telescopic arm to mount the pile on the drive shaft.
  12. 12 . The apparatus of claim 11 , wherein the drive shaft guide comprises a collar through which the drive shaft extends through and at least one arm extending between the collar and the telescopic arm.
  13. 13 . The apparatus of claim 1 , further comprising at least one guide assembly for at least partially enclosing around a periphery of the pile at or near a lower end of the mast for guiding the pile as it is driven into the underlying ground surface.
  14. 14 . A method of loading a non-vertically oriented pile resting in a rack or atop a trailer with an apparatus according to claim 1 , said method comprising: moving the carriage and drive assembly relative to the mast so that the drive shaft aligns with a drive end of the pile; extending the at least one clamping assembly relative to the carriage and drive assembly so that the at least one clamping assembly extends beyond a distal end of the drive shaft; clamping the drive end of the pile with the at least one clamping assembly; retracting the at least one clamping assembly relative to the carriage and drive assembly to mount a clamped said pile onto the drive shaft; and rotating the carriage and drive assembly relative to the mast to the operable position.
  15. 15 . The method of claim 14 , wherein the moving comprises sliding the carriage of the carriage and drive assembly along the mast and the rotating the drive mount to align the drive shaft relative to the drive end of the pile.
  16. 16 . The method of claim 14 , wherein the clamping comprises actuating clamping member of the at least one clamping assembly to clamp about the drive end of the pile.
  17. 17 . The method of claim 14 , wherein the retracting retrieves a clamped said pile and mounts the pile onto the drive shaft.

Description

TECHNICAL FIELD The present invention relates to a pile installation apparatus and method of use thereof for loading and installing a pile into an underlying ground surface. BACKGROUND Screw piles are a screw-in piling used for building foundations in the construction of buildings and other structures. A typical screw pile is formed from high-strength steel and includes a shaft having an insertion end portion and an opposed drive end portion. The insertion end portion usually includes one or more helical screws or blades extending outwardly therefrom. In order to insert a screw pile into a ground surface, the pile is mounted to drilling equipment supported by a support vehicle and is rotated and pressed downwardly so as to cause the one or more helical screws or blades to bite and screw into the ground. Once properly inserted, the weight borne by the screw pile is distributed from the helical screw or blade onto underlying earth and the earth positioned above the helical screw or blade assists the pile in resisting any lifting forces applied to the pile and in maintaining the screw pile in the ground. However, a problem in general with the screw pile installation process is that each pile is manually mounted onto the drilling equipment. Apart from posing a significant safety risk, the manual mounting process is both labour and time consuming, often involving a team of labourers to handle, align and slide the screw pile in place on the drilling equipment. The above problem is further emphasised on remote work sites where a plurality of screw piles need to be installed, such as, e.g., solar energy installations. The additional cost of having a team of labourers present at a remote work site to handle and mount each screw pile can be prohibitive.

SUMMARY OF INVENTION Embodiments of the present invention provide a pile installation apparatus and method of use thereof, which may at least partially address one or more of the problems or deficiencies mentioned above or which may provide the public with a useful or commercial choice. According to a first aspect of the present invention, there is provided a pile installation apparatus for loading and installing a pile into an underlying ground surface, said apparatus including: a mast adapted to be arranged in a substantially vertical position above the ground surface;a vehicle mount for mounting the mast to a support vehicle adapted to raise and lower the mast to and from the substantially vertical position and to otherwise manipulate and transport the mast;a carriage and drive assembly slidably mounted to the mast for vertical movement therealong and configured for rotational movement relative to the mast, said assembly including a rotational drive and drive shaft for mounting of a drive end of the pile thereon, said carriage and drive assembly configured to be rotatable relative to the mast between a loading position for loading a non-vertically oriented pile onto the drive shaft and an operable position for driving the pile into the underlying ground surface; andat least one clamping assembly including a pair of opposed clamping members for clamping the drive end of the pile and retaining the pile relative to the drive shaft at least while the carriage and drive assembly rotates to the operable position. According to a second aspect of the present invention, there is provided a carriage and drive assembly for use with the pile installation apparatus of the first aspect, said assembly slidably mounted to the mast for vertical movement therealong and configured for rotational movement relative to the mast, said assembly including a rotational drive and a drive shaft for mounting of a drive end of a pile thereon, said carriage and drive assembly configured to be rotatable relative to the mast between a loading position for loading a non-vertically oriented pile onto the drive shaft and an operable position for driving the pile into the underlying ground surface. According to a third aspect of the present invention, there is provided a clamping assembly for use with the pile installation apparatus of the first aspect, said clamping assembly including a pair of opposed clamping members for clamping a drive end of a pile and retaining the pile relative to the drive shaft at least while the carriage and drive assembly rotate to an operable position. Advantageously, the pile installation apparatus of the present invention provides a safe and efficient way to individually load and install screw piles. The mast and carriage and drive assembly enable piles to be loaded from a horizontal resting position, such as, e.g., on a rack, and be mounted relative to the drive shaft without the need for any manual labour other than an operat
