Mini excavators have become indispensable equipment in the construction industry and are widely used in all kinds of buildings, gardens and public utility projects. With its compact design and versatility, mini excavators have become the first choice for professionals and DIY enthusiasts.
However, before operating a small
excavator, it is essential to understand the basic operating steps. This includes preparation before operation, basic control operation, use and disassembly of the bucket, and most importantly, safe operation points.
Fortunately, mini excavators are one of the easiest pieces of heavy equipment to use. This guide will provide you with detailed operation steps, and you can also refer to our video tutorial "How to operate a Mini Excavator" to help you quickly master the operation skills.
Mini excavators, also known as compact excavators, are available in a variety of brands and models, and can be equipped with different accessories according to project requirements. Although the functions of different models of excavators vary, the purpose of operation of all small excavators is similar. Before operation, it is recommended to read the operation manual and equipment capacity chart carefully and familiarize yourself with the cab layout, control lever, pedal and joystick use.
Safety checks are essential when operating any heavy machinery. Before starting a small excavator, be sure to carry out a thorough inspection. Ensure that the track is not visibly worn or damaged, check the levels of various liquids, and confirm that accessories are securely installed.
When checking the track, be sure to look for excessive wear or cracks and make sure the track is properly tightened. Refer to the user manual to ensure that the track is properly sealed and adjust it with grease fittings or sleeves if necessary.
In addition, check coolant, oil and fuel levels, as well as the condition of fuel filters, oil filters, water/fuel separators and hydraulic connections. Ensure that all liquids are kept at normal levels and that the filter does not leak.
Wearing proper personal protective equipment (PPE) such as hard hats, gloves, steel-toed boots and goggles is also an important safety measure when operating a small excavator.
When entering the cab, make sure to use three contact points and stay within the safe zone. When started, facing the direction of the shovel blade, this is the "front" of the small excavator. When operating a small excavator, it mainly relies on five joysticks. There are two drive rods in front of the operator's seat, one on the left and two on the right. Forward and backward action is achieved by pushing or pulling both front rods simultaneously. The steering operation is done by pushing or pulling the corresponding joystick. To rotate the cab, use the left joystick to push left or right.
For many mini excavators, the right pedal controls the rotation of the boom, with the left side rotating to the left and the right side rotating to the right. The forward and backward movement of the left joystick controls the up and down of the boom. The smaller joystick on the right controls the bucket and its accessories, pulling the bucket to the left to curl, pushing the bucket to the right to unfold, pushing the arm forward to lower, and pulling the arm back to rise. Another larger joystick on the right adjusts the balance of the blade, pushing it forward to lower it to the ground and pulling it back raises it.
It is important to note that these controls apply to the ISO mode of operation. With the SAE mode of operation, the joystick controls are switched from side to side. When changing the operation mode, shut down the excavator. The position of the control switch varies according to the model. You are advised to refer to the user manual.
When conducting excavations and excavations, efficient excavations and excavations often require many years of experience. As a novice, it is very important to master these movements gradually. When digging, follow the following best practices: Ensure that there are no underground facilities in the work area, and choose a small excavator model that is suitable for the project. If the working environment is more rocky, choose a more powerful excavator; If the working area is far away, choose a model with a longer boom. When digging, keep the balance blade on the ground to increase stability and strength.
Small excavators can also be used to load materials onto trucks. This mainly depends on the crimping function of the boom. When loading and unloading materials, pay attention to the specific location of loading and dumping, and select the appropriate size of the small excavator. Select an appropriate excavator model based on the material type. A sturdy excavator is suitable for moving heavy objects such as bricks and concrete, while a smaller excavator can be used for moving light objects such as soil.
Safety is a top priority when operating a small excavator. Always wear your seat belt and be aware of your surroundings. It is important to understand the layout of the work site, obstacles, and the movement of people. Depending on the type of cab, safety measures may vary. Closed cabs have more blind spots, but open cabs are more susceptible to flying objects. Select the type of cab suitable for the working environment to ensure safe operation.
Operating in difficult terrain requires flexibility, understanding the limitations of the machine, and adopting strategies to deal with uneven terrain or tight Spaces. Small excavators are designed for tight Spaces, but still require careful operation.
Maintenance after Operation
After the job is done, operate according to the standardized shutdown procedure and perform routine maintenance tasks such as lubrication and cleaning to extend the service life of the equipment. At the same time, perform a loop check similar to the one before startup to ensure that the device is always in good condition.
Operating a small excavator is a skill that requires a great deal of focus and patience. For beginners, successful completion of the project not only depends on a basic understanding of the equipment, but also requires sufficient attention to every detail of the operation process. By constantly getting familiar with the functions and operation processes of the equipment, beginners can gradually establish a sense of control over the machine, so that they can confidently operate in a variety of work scenarios.
Compliance with safety protocols is key to ensuring the safety of people and equipment during operations. Knowing and following all safety guidelines, including but not limited to wearing appropriate personal protective equipment, conducting thorough equipment inspections before and after operation, and remaining alert at the job site, can significantly reduce the risk of accidents.
