多年以前在美国看见一种简便快捷的自装卸卡车,在钻机搬安中起到强大作用,对页岩气钻井的模块化钻机的低成本、快捷搬运尤为实用。其示意图如图1。在普通卡车或平板车上装有一部液压驱动绞车及钢缆,作为货物装卸的牵引动力,尾部装有一只滚筒,以便装卸撬装设备时,减少摩擦、保护车体(见图2)。整个装卸过程不需吊车,安全快捷(见图3)。 Many years ago saw a quick and easy self-unloading truck in the United States, which played a powerful role in moving rigs and was especially practical for low cost and quick handling of modular drilling rigs for shale gas drilling. The schematic diagram shown in Figure 1. A common truck or flatbed truck is equipped with a hydraulically driven winch and cable to act as a traction power for cargo handling. A tail drum is equipped with a roller to reduce friction and protect the car body (see Figure 2). The entire loading and unloading process without crane, safe and efficient (see Figure 3).
