For the purposes of this document, the following terms and definitions apply. 3.1 dump truck A vehicle equipped with lifting and/or horizontal unloading devices (conveyor belt, movable floor, push plate, etc.) that enables automatic unloading of goods from the carriage. 3.1.1 tipper A dump truck that uses a lifting device to tilt the carriage at a certain angle, thereby unloading the materials inside the carriage. See Figure 1 for a schematic diagram. NOTE. This typically includes rear-tilt dump trucks and side-tilt dump trucks. 3.9 width inside the carriage The horizontal distance between the vertical planes with the largest inner areas of the left and right boards. It is represented by the letter W, see Figure 7.4 Technical requirements
4.1 Complete vehicle 4.1.1 General requirements 4.1.1.1 The external dimensions, axle load and mass limits shall comply with the provisions of GB 1589. 4.1.1.2 Operational safety shall comply with the provisions of GB 7258. 4.1.1.3 The power take-off unit shall comply with the provisions of QC/T 319. 4.1.2 Assembly requirements 4.1.2.1 All moving parts shall operate smoothly. There shall be no interference, lateral movement, collision, or jamming. 4.1.2.2 All pipes and wiring harnesses shall be arranged neatly and securely fixed. They shall not rub against or interfere with moving parts. 4.1.2.3 All operating handles and valves shall be installed for easy operation. Operating instructions shall be placed in easily visible locations. The safety protection devices shall be provided. 4.1.3 Process requirements 4.1.3.1 The welding quality of welded parts shall conform to the requirements of JB/T 5943.The weld seam shall be smooth and uniform, free from defects such as burn- through, incomplete welding, cracks, porosity, and slag inclusions. Weld slag shall be thoroughly cleaned. 4.1.3.2 All fasteners shall be treated with rust prevention. Exposed ferrous metal parts shall be treated with corrosion prevention. 4.1.3.3 The quality of paint coatings shall comply with the requirements of QC/T 484. Coatings and chemical treatment layers shall comply with the requirements of QC/T 625. 4.1.4 Safety requirements 4.1.4.1 Dump trucks shall be equipped with acoustic and optical alarm devices. When the carriage of a lift-type dump truck is not in contact with the frame (subframe) or when the unloading device is in operation, the alarm device shall be able to issue an alarm to the driver and operators. 4.1.4.2 Dump trucks shall be equipped with dump covers to prevent material spillage. Leakage and spillage shall not occur during transportation. 4.1.4.3 Dump trucks shall be designed and manufactured with safety measures in place to prevent unintended unloading. 4.1.4.4 Effective measures shall be taken to ensure that the vehicle speed does not exceed 10 km/h when the carriage has not been returned to its initial state. 4.1.4.5 Dump trucks shall have safety warning signs prominently displayed around the operating devices.
