卡尔玛集装箱正面吊是我公司从事吊装作业主要设备,该机在运行过程中吊具有时出现故障,本文在分析该型正面吊吊具工作原理的基础上,介绍该机吊具常见故障排查方法。1.工作原理该型正面吊吊具工作原理如图1所示。图中实线箭头代表电信号走向,虚线箭头代表液压信号走向。当电信号和液压信号都能正常导通时,吊具才能正确执行各个部位的动作(图中直线所示)。由图1可知,当操纵液压手柄给吊具控制器发出动作信号后,若吊具动作
Kalmar container front crane is my company engaged in hoisting operations of the main equipment, the aircraft in the operation of the crane there is a time of failure, this paper analyzes the principle of this type of positive crane on the basis of the machine to describe the common method of troubleshooting spreader . 1. Working principle This type of positive hanging spreader working principle shown in Figure 1. The solid line in the figure represents the direction of the electrical signal, the dotted line represents the hydraulic signal in the direction of arrow. When the electrical signals and hydraulic signals can be normally turned on, the spreader can correctly perform all parts of the action (shown in the straight line). As can be seen from Figure 1, when manipulating the hydraulic handle to the spreader controller sends an action signal, if the spreader action
