The main function of the crawler-type rotary platform of a pile driver is to bear the upper weight and facilitate the rotational movement of the upper vehicle. The platform acts as a counterweight at the rear, with the diesel engine positioned horizontally in front of the counterweight. The radiator is installed on the right side of the diesel engine (fan end), and the main hydraulic pump is directly mounted on the diesel engine's flywheel. In front of the engine room, there are auxiliary winches, the main winch, and the rotary reducer in sequence. The rotary support is mounted at the bottom of the platform, and the central water tap at the bottom also passes through the platform here, connecting to the multi-way valve with a hose. At the front left of the platform, the cab assembly, all pilot control pipelines, and electronic control harnesses are installed and connected through the cab floor to components on the platform (such as the diesel engine, main hydraulic pump, multi-way valve, etc.). Other spaces are equipped with a diesel tank, electronic control cabinet, auxiliary valves, oil cooler, toolbox, etc. The overall layout should ensure that the weight on both sides of the platform is essentially balanced, with the center of gravity tilted backward. The crawler-type pile driver uses tracks for movement because sometimes the pile driver will face areas with poor construction environments. Using a crawler pile driver can not only carry out construction effectively without encountering inefficient underground conditions but also significantly improve the safety factor and reduce the likelihood of rollover accidents. Lastly, I would like to remind the heads of crawler pile driver manufacturing companies that before construction, we need to conduct a comprehensive and accurate analysis of the construction geology. Pile drivers have high geological requirements, and the torque needed varies with different geologies, so we need to perform a test before construction.
