1 引言目前,内河小型散货码头卸船作业机械化水平不高,有的还靠人力搬运,有的采用固定式臂架回转起重机,有的是用桅杆起重机及单绳或双绳抓斗。这些起重机在卸船作业时需要货船移动配合才能完成,降低了卸料的效率和减少了码头的有效泊位。同时,这些起重机操作人员工作环境较差,操作人员的劳动强度大。为了提高小型码头的卸料效率和增加码头的有效泊
1 Introduction At present, the mechanization of small-sized inland river bulk carrier unloading operations is not high, and some rely on manual handling. Some use fixed-boom rotary cranes, others use mast cranes and single or double rope grapples. These cranes require the cargo ships to move and cooperate when unloading a ship, which can reduce the efficiency of discharging and reduce the effective berth of the wharf. At the same time, these crane operators are in a poor working environment and the operators are labor-intensive. In order to improve the discharge efficiency of small wharf and increase the effective wharf of the wharf
