挖掘装载机支腿的安全性和可靠性十分重要,国标GB 25684.4-2010对挖掘装载机支腿报警提出了具体要求。但是现有挖掘装载机支腿报警装置结构复杂、组装繁琐,受内、外支腿装配精度限制,报警装置经常损坏。为此,我们对现有支腿报警装置进行了改进。本文介绍新型支腿报警装置组成、原理和控制方法。1.组成和原理该新型支腿报警装置由前进电磁阀、后退电磁阀、挡位选择器、左支腿报警灯、右支腿报警
Backhoe loaders backhoe mining safety and reliability is very important, national standard GB 25684.4-2010 backhoe loaders excavator raised the specific requirements of the alarm. However, the existing backhoe loader leg alarm device has a complicated structure, is complicated to assemble, is limited by assembly accuracy of inner and outer legs, and the alarm device is often damaged. To this end, we have improved the existing leg warning device. This article describes the new leg alarm device composition, principles and control methods. 1. Composition and Principle The new outrigger alarm consists of a forward solenoid valve, a reverse solenoid valve, a gear selector, a left leg warning lamp and a right leg alarm
