For shipped components, if a single component exceeds 3, it is advisable to mark the weight and center of gravity position with paint on easily visible parts to avoid damage to component gussets, high-strength bolt connection surfaces and other important parts during the loading, unloading and lifting processes. Appropriate protective measures, scattered parts, etc. must be fastened with bolts and wires into bundles or packed for shipment according to the same category. The transportation plan for large or heavy components should be prepared based on the driving route, performance of transportation vehicles, terminal conditions, and transportation vessels. In the transportation plan, it is necessary to focus on the stacking conditions and construction period requirements of the hoisting project to prepare the transportation sequence of the components.
When transporting components, the fulcrum of the vehicle component on the transport vehicle should be selected based on the length, weight and cross-sectional shape of the component. The length of extension of both ends and the binding method should ensure that the component does not produce permanent deformation and does not damage the coating. Components must be lifted according to the designed lifting points and must not be arbitrarily lifted.
Height limit for road transportation and shipment. If it is necessary to pass through a tunnel, the height limit must not be exceeded if the component grows beyond the vehicle body.
