The Complete Guide To Underground Loader

I. Introduction

in brief, you can use an underground loader to transport earth and rock waste when you mine underground. In addition, the underground mining loader can also fill in the uneven ground. Underground loaders have many advantages, such as high speed when working, and more importantly. Therefore, they are effortless to operate. If you want to buy underground mining equipment, Below I will introduce the underground mining loader in detail for you.

II. Main Components Of Underground Loader

To sum up, the main components of the underground mining loader include the engine, torque converter, gearbox, front and rear drive axles:

1. Firstly, the engine is the most important part of the underground loader

2. Secondly, the torque converter of the lhd loader contains three pumps:

• The working pump is responsible for supplying lift and dump pressure oil.
• The steering pump is responsible for supplying steering pressure oil.
• The Pump is responsible for changing the speed

3. Further, working hydraulic oil circuit of lhd loader:

• hydraulic oil tank,
• working pump,
• multi-way valve,
• lift cylinder
• dump cylinder

4. Moreover, the traveling oil circuit of the lhd loader:

• traveling pump, all the way into the torque converter and one into the gear valve,
• transmission clutch

5. Drive of underground loader: drive shaft, main differential, wheel reducer

6. Steering oil circuit of underground mining loader:

• fuel tank,
• steering pump,
• steady flow valve (or priority valve) steering gear,
• steering cylinder

7. Gearbox of lhd loader:

• integrated (planetary type) 
• split (fixed shaft type)

III. Working Device Of lhd mining equipment

There are two main functions of the underground mining loader. First, the underground loader scoops up the ore in the tunnel. Then, the underground loader transports the material that needs to be transported to another place for storage. That is to say, the combination of various components completes this series of actions.

Most importantly, the front part of the underground mining loader is the bucket, which is responsible for scooping up the material. The boom connects the bucket to the main body of the LHD loader. You can control the bucket in the cab by operating the linkage and rocker arm for construction.

Meanwhile, if the underground mining loader is working, close the cylinder of the bucket, and the boom cylinder can move up and down so that the bucket can be moved. Most importantly, When you operate the machine, pay attention to maintaining the dip angle of the bucket. That is to say, our generally considered smoother bucket inclination is 45 degrees.

IV. Development Trend of Underground Loaders

In the beginning, underground loaders were characterized by a low level of operation. The quality of the underground mining loader is not good, but the price is also relatively quiet. However, with the continuous improvement of R&D technology in various countries worldwide, lhd loaders are also more and more developed. To sum up, the development trend of lhd mining equipment mainly includes the following aspects.

1. Medium loaders

Medium loaders will become more and more popular. However, large and small underground loaders will gradually lose their market advantages.

2. Customized production of underground loaders

That is to say, there will be more and more customized production of underground loaders. underground mining loader manufacturers will provide personalized services according to customer needs.

3. More systematic

The structure of the underground loader will be more systematic. For example, the shock absorption effect, heat dissipation effect, and dustproof effect of the lhd loader will become very good.

4. Automatic shifting

The gearbox of the underground mining loader can realize automatic shifting. As a result, this saves a lot of energy.

5. Safe and comfortable driving environment

The cab of the underground loader will refer more to the style design of the car cab. We know that the environment of undercover mining operations is very harsh, so we provide drivers with a safe and comfortable driving environment.

6. More environmentally friendly

The overall design of the underground loader will be more environmentally friendly. Our environmental awareness is gradually strengthened, and the ecological protection of underground mining is becoming more and more critical. Noise, exhaust gas, and dust are the primary sources of pollution from underground mining. Our lhd loader will minimize the pollution of the environment

7. More convenient

Make the maintenance of the underground mining loader more convenient. Once the machine goes underground and starts working, the ideal state is not to lift the well easily. Therefore, we have investigated more straightforward methods for judging mechanical faults. According to this method, the driver can quickly master the maintenance method of the lhd mining equipment.

V. Types Of Underground Loaders

There are generally three criteria for the classification of underground loaders. Most importantly, the engine power, rotation mode, and walking mode are commonly used to classify. Below we analyze the table in detail.

1. Engine power of lhd mining equipment:

Purpose of loader underground

Uses of Load Haul Dump (LHD) Loaders There are many uses in underground mining operations. First of all, the most basic use is to load and unload minerals and muck. This will ensure the orderly progress of the construction progress. Second, underground loaders can do light digging work. In short, as long as you carry out undercover mining operations, you cannot do without the loader underground.

VI. How to choose the top underground mining loaders

When buying underground installations, you should do your research in advance. It would help if you learned more about the types and characteristics of lhd mining equipment. Finally, it would be best to choose a suitable lhd loader according to the actual environment of underground mining. Below I’ll give you four considerations for selecting an loader underground.

1. Type of underground lhd machines: In general underground mining sites choose an underground loader with multiple tires and snow chains.
2. The power of the underground mining loader: In most cases, we will choose a diesel engine.
3. Transmission type of underground loader: hydraulic-mechanical transmission is generally used.
4. Braking form of underground mining loader: When selecting a loader, the braking performance of the loader should be fully considered, including multiple braking, parking braking, and emergency braking. There are three types of brakes: shoe type, caliper disc type, and wet multi-disc type.

VII. The running-in period of the underground loader

As we all know, whether it is an underground lhd machine or an underground loader, it will go through a 60-hour running-in period or a running-in period. The advantages of underground mining loaders running-in period are:

1. Make the underground loader work properly
2. Reduced maintenance times forunderground mining loaders
3. If there is no problem during the running-in period, it will prolong the service life of the underground loader
   However, many people often ignore this problem when using the underground mining loader. They overuse underground lhd machines during the break-in period. Although this method saves time initially, it dramatically shortens the service life of the underground loader. Therefore, we suggest that every loader driver should attach great importance to the running-in period of the underground loader.
   

VIII. How to use and maintain an underground mining loader

1. Train operators

The first important thing is that there must be an instruction manual so that the operator can operate the machine correctly under the guidance of the information. Before using any new device, we must read the instruction manual carefully.
In the same way, operators of underground mining loaders need to receive training in their use. 1. The operator of the underground loader should receive training in advance.

There is another way of movement: the production plant and the on-site demonstration training by sending people in person. Whichever method is used, make sure the driver is familiar with the driving technique before using the underground loader.

2. Control the working hours of the underground mining loader

It is worth noting that do not use the underground loader for long. Especially in the running-in period of the machine, the workload of the underground lhd machines should be controlled within half of the rated workload.

3. Observe abnormal data

When abnormal data appears on the instrument of the underground loader, stop the operation immediately. Carefully check the various parts of the machine to find out the cause of the failure. Wait until the instrument data returns to normal before using the underground lhd machines.

4. Check the underground loader daily

After each day’s work, clean up the underground lhd machines in time. After that, check loose parts and tighten them in time. This is to prevent minor problems from being overlooked and causing more significant issues.

5. Refill oil in time

Subsequently, check the lubricating oil, hydraulic oil, coolant, brake fluid, and fuel oil (water) daily before starting work. If any missing oil is found, it should be replenished in time.

After the break-in period of the underground loader has passed, it is necessary to maintain it regularly. Let’s summarize how to use the underground lhd machines:
(1) Firstly, train the operator
(2) Secondly, reduce the workload of the loader during the running-in period
(3) Further, check the status of the loader every day, find problems, and repair them in time
(4)Moreover, keep the lubricating fluid of the loader sufficient to prevent the wear of parts.
(5) In addition, maintain and maintain the loader every year
To sum up, only through this method can the loader be used for a longer time and work more efficiently. This also means that the loader can bring you greater profits.

IX. How to Operate an Underground Loader

1. Above all, the operator shall perform according to the standard.
   Before the driver is ready to enter the cab of the underground loader, he undergoes rigorous training. The driver should be familiar with the vehicle in advance and demonstrate how to use it in a safe area. In addition, the driver should master the fault judgment method and simple maintenance knowledge.
2. Subsequently, only one person can operate the machine. No other people can stand on the loading vehicle to prevent personal injury.
3. Certainly, the body cannot touch the carriage.
   When the driver is carrying out mining operations, the bucket should be raised slowly. It must be ensured that the bucket does not touch the carriage. Otherwise, the material will spill and cause damage. Take special care not to pass the bucket over the cab because this is dangerous behavior.
4. Do not slam on the brakes when the driver drives the underground loading vehicle through the downhill section. The safest way is to slow down early to prevent landslides and loss of vehicle control.
5. If the underground loader passes through the water section and reaches the safety zone, it should stop and check. If the brakes of the loader fail, the brakes should be applied several times in a row.
6. There should be no people around when the underground lhd machines are loading and unloading. Other workers should stay away from the loader.
7. Most importantly, do not work at the maximum speed of the loader.
8. In addition, Lower the bucket to the ground when the driver finishes work and is ready to leave the loader. Finally, shut the engine off and leave the cab.
