Abstract: A low-weight tipper unit or unloading system (10) used in the course of unloading raw materials (12) from haul vehicles (16) typically used in mining and construction operations. The unloading system (10) comprises a support surface (18) configured for operatively receiving the vehicle (16). The support surface (16) is fixed to a base structure (20) and pivotable between a first position and a second position. A retaining arrangement (24) is provided for retaining the vehicle (16) relative to the support surface (18) in use. An energy harnessing arrangement (44) harnesses energy when the support surface (18) is pivoted under load to the second position.

Abstract: A lightweight haul vehicle (10) comprising a haul carrier arrangement (16), typically utilised in mining and/or construction operations for hauling raw material. The vehicle (10) comprises a chassis (14) for supporting the haul carrier arrangement (16). The haul carrier arrangement (16) comprises a support arrangement (18) fixed relative to the chassis (14) and a carrier arrangement (20) in the form of a sheet of flexible material (22) suspended from the support arrangement (18) and supported to form an open-top receptacle (26) for operatively receiving raw material.

Abstract: A system for placing a sample at a predefined measurement location for measuring an optical property of that sample. The apparatus includes a measurement platform for supporting the sample at the measurement location, the measurement platform having an orifice therein beneath the measurement location, and a nozzle configured to retain the sample therein when a vacuum is applied to the nozzle. The sample is contacted by the nozzle, and a vacuum is applied to the nozzle so that the sample is retained therein by air pressure. The nozzle with the sample retained therein is then transported to the measurement location. The vacuum at the nozzle is disabled to release the sample from the nozzle, and a vacuum is applied to the orifice in the measurement platform so as to retain the sample on the measurement platform. The nozzle is then retracted away from the measurement platform.
