The load sensing variable speed control system of small loader can shorten the operation cycle, reduce the fuel consumption rate by 15%, improve the operation efficiency and operation economy, reduce the shift impact caused by the change of driving direction or the shift when the engine is at high speed, and reduce the driver's work fatigue.

装载机负荷传感系统可把装载机对动力的需求减少到惊人的程度，装载机上配有电子伺服控制及信息系统由液晶显示屏和键盘组成，用来显示和记录各种信息，其自动诊断功能记录机器故障并储存所有相关信息，通过编码可以防盗计算机管理和监控是90年代国外装载机发展的一个重要标志计算机管理监控系统能连续管理/监控装载机的数十项参数，具有故障诊断和报警功能，能记录、处理装载机作业的各种信息，并能用液晶显示器显示部件的工作状态。

The load sensing system of the loader can reduce the demand of the loader for power to an amazing extent. The loader is equipped with an electronic servo control and information system, which is composed of LCD and keyboard to display and record various information. Its automatic diagnosis function records machine faults and stores all relevant information, Anti theft computer management and monitoring through coding is an important symbol of the development of foreign loaders in the 1990s. The computer management and monitoring system can continuously manage / monitor dozens of parameters of loaders, has fault diagnosis and alarm functions, can record and process all kinds of information of loader operation, and can display the working state of components with LCD.

连杆机构可承受非常大的扭矩载荷，具有很好的可靠性、耐用性和平行举升机构相类似的作业性能工作装置能以水平位置提升或降下放在托板上的物料，可配用多种作业装置，更大限度地减少司机由地面到更大高度对铲斗倾斜角的调整。

The connecting rod mechanism can bear very large torque load and has good reliability and durability. It has similar operation performance with the parallel lifting mechanism. The working device can lift or lower the materials on the support plate in a horizontal position. It can be equipped with a variety of working devices to reduce the adjustment of bucket inclination angle from the ground to a greater height.

装载机在工作3000小时之后，会出现仪表台、驾驶室抖动现象，且抖动现象越来越严重，以驾驶室、整机也产生抖动。抖动现象造成该机物料称重不准确，无法正常使用。下面山东装载机的技术人员给大家分析一下引起抖动的原因有哪些？

After the loader works for 3000 hours, the instrument panel and cab will shake, and the shaking phenomenon is becoming more and more serious, so that the cab and the whole machine also shake. The shaking phenomenon causes the material weighing of the machine to be inaccurate and cannot be used normally. Next, the technicians of Shandong loader will analyze the causes of jitter?

1、装载机液压系统采用转向优先方式，转向泵输出的压力油与工作泵输出的压力油合流后向工作装置供油。工作泵只有在工作装置动作时才承受负荷，而转向泵不但在工作装置动作时承受负荷，转向时也承受负荷，因此转向泵工作时间相对较长、磨损较大。

1. The hydraulic system of the loader adopts the steering priority mode. The pressure oil output by the steering pump flows with the pressure oil output by the working pump and supplies oil to the working device. The working pump only bears the load when the working device acts, while the steering pump not only bears the load when the working device acts, but also bears the load when steering. Therefore, the working time of the steering pump is relatively long and the wear is large.

2、装载机在优先阀阀体、阀芯、调压弹簧和压力油的共同作用下，EF口开启与闭合按照一定频率相互变换，便发生一定频率的振动。由于该振动与仪表台、驾驶室的固有振动频率接近，导致仪表台、驾驶室发生共振。

2. Under the joint action of priority valve body, valve core, pressure regulating spring and pressure oil, the opening and closing of EF port of loader change with each other according to a certain frequency, and vibration of a certain frequency occurs. Because the vibration is close to the natural vibration frequency of the instrument panel and cab, the instrument panel and cab resonate.
