Underground small loader is a kind of mechanical equipment, which is mainly used for the collection, transportation and construction loading of gravel soil materials in various mines, hydropower and tunnel projects, such as phosphate mine, iron mine, copper mine, gold mine, silver mine, lead-zinc mine, coal mine roadway, etc. What should be paid attention to when the loader starts? Especially for those who start the loader for the first time, they don't know much about the loader and its operation. What are the matters needing attention when starting the underground loader?

小铲车井下装载机运用和操作矿用装载机前，要熟练与该类型装载机有关各种技术文件和资料，了解机器的功能和结构特色，把握每根操作杆或操作手柄以及各种外表的方位和效果，以合理地运用机器，前进机器运用的寿数；装载机开动前要做好开车前的准备工作，检查各部件是否正常外表、润滑、发起、制动、冷却检查是否符合技术要求，轮胎的气压油位和操作手柄是否灵敏。

Before using and operating the mine loader, we should be familiar with all kinds of technical documents and materials related to this type of loader, understand the function and structural characteristics of the machine, and grasp the orientation and effect of each operating rod or handle and all kinds of appearance, so as to use the machine reasonably and advance the service life of the machine; Before the loader starts, it is necessary to make preparations before starting, check whether the components are normal, whether the appearance, lubrication, initiation, braking and cooling meet the technical requirements, and whether the tire pressure, oil level and operating handle are sensitive.

井下小铲车装载机高速跋涉时用两轮驱动，低速铲装时用四轮驱动，高速跋涉，为了前进发起机的功率运用，可将变矩器离合器的操作阀油路接通，使变矩器与泵轮与涡轮结为一体，成为刚性联接以削减功率丢失，抵达高速跋涉的意图；改动跋涉的方向，改换高低速档或驱动桥手柄都要在泊车后进行装载机作业时，发起机水温文变矩器的油温均不得超越规则值，因为装载作业，油温超越容许值应泊车冷却。

In order to use the power of the forward initiator, the oil circuit of the operation valve of the torque converter clutch can be connected, so that the torque converter, the pump wheel and the turbine are integrated into a rigid connection, so as to reduce the power loss and achieve the purpose of high-speed trekking; When changing the direction of trekking, changing the high and low speed gear or driving axle handle, the loader operation should be carried out after parking, the water temperature of the initiator and the oil temperature of the torque converter should not exceed the regular value, because when the oil temperature exceeds the allowable value during the loading operation, it should be cooled by parking.

井下装载机所运用的燃油要清洁，并经过48小时以上的沉淀，燃油商标应符合规则质量要求，液压体系用油和变速箱，变矩器用油符合要求；按规则进行保养与润滑，熟知各润滑点的方位。发起机发起后就怠速空转，待水温抵达55℃，气压升起复兴步跋涉。在山区坡道上跋涉，应避免发起机熄火，下坡跋涉时不容许发起机熄火，否则液压转向器，失灵形成事端。

The fuel used by the underground loader should be clean and precipitated for more than 48 hours. The trademark of the fuel should meet the quality requirements of the rules. The oil used for hydraulic system, gearbox and torque converter should meet the requirements; According to the rules of maintenance and lubrication, familiar with the location of each lubrication point. When the engine starts, it idles, and when the water temperature reaches 55 ℃, the air pressure rises, and then it trudges. When trekking on the mountain slope, the engine should not be shut down. When trekking downhill, the engine should not be shut down, otherwise the hydraulic steering gear will fail and cause trouble.
