Types of used excavators for sale in UAE

An excavator is an earth-moving equipment used mainly in the construction sector. It consists of a cab, arm, bucket, and rotating platform mounted on a tracked or wheeled chassis. Excavators perform multiple functions thanks to the variety of attachments they can be fitted with, such as the used excavator bucket for sale in UAE or break for demolishing concrete structures, for instance.

Excavators are classified into many types based on various factors, as follows.

• Wheeled/tracked excavators: Excavators that have a tracked undercarriage resemble tanks and are well adapted to moving around construction sites where the ground is uneven. Excavators with wheels are ideally suited to move faster over long distances on paved roads.
• Mini/standard excavators: Mini excavators are characterized by a short tail, light weight, and maneuverability. They are well suited for digging in tight spaces without risking to overturn when facing a slope. Standard excavators are the go-to model when there are no space constraints.
• Knuckle excavators: Also known as the articulated or joint-arm excavator, this model consists of an arm with a joint in the middle, resembling a human arm. The joint enables the operator to control the arm with great precision when performing tasks such as demolition or dredging in tight or high-reach areas.
• Hydraulic excavator: This is the most popular excavator model on the market. It makes use of a hydraulic system to power its arm and bucket, which are the main digging components, by utilizing the hydraulic pressure from the fluid moving in the hoses that connect to the motor.
• Suction excavator: This specialized excavator uses a high-powered suction system to safely remove and expose underground utilities, precisely dig, or perform non-invasive excavation. It is often used when protecting delicate structures or minimizing disruption is crucial.

The five types discussed above are but some of the excavator models manufacturers make to meet various demands. When buying an excavator for use in a particular construction task, it is essential to know the terrain and the nature of the task.

Specification and maintenance of used excavators for sale in UAE

Used excavators for sale in UAE come with specifications based on types and models. Here are the common specifications corresponding with the relevant types and models of excavators:

• Operating weight: The operating weight of used excavators for sale in UAE is an important specification. It also includes the total weight of the excavators, such as the chassis, counterweight, and superstructure. The operating weight affects the stability and digging capacity of excavators. For instance, mini excavators usually have an operating weight from 0.8 tons to 6 tons. In contrast, standard excavators with a larger size and higher capacity have an operating weight from 10 tons to over 100 tons.
• Engine power: Engine power is another major specification for used excavators for sale in UAE. It directly controls the digging and driving power of excavators. The engine power of mini excavators is usually lower, from 10 to 50 kW. Standard and large excavators have higher engine power. For standard/existing excavators, engine power ranges from 75 to 150 kW. Large excavators are more powerful for heavy work. Their engine power might reach up to 400kW or more.
• Hydraulic system: The hydraulic system is an essential part of an excavator. It controls the movement and digging of the arm, bucket, and other accessories through the hydraulic oil. The specification of an excavator’s hydraulic system will directly influence its digging power and flow rate. Some mid to large excavator models have several hydraulic lines. They can be compatible with different attachments, such as hydraulic hammers and shears.
• Cab and control system: Certain specifications of the used excavators for sale in UAE are related to operating and controlling the machine. For instance, the model and function of the cab fall into this category. They are relevant to the comfort and convenience of the operator. Other specifications include the type of manual and electronic control, as well as the assisted technology. Some excavators are equipped with intelligent technology, such as an automated control system. This kind of technology can enhance the accuracy and efficiency of excavation tasks.

Maintenance

Regular maintenance keeps used excavators functioning well and prolongs their lifespans. Here are some maintenance tips for used excavators for sale in UAE.

• Daily inspection: Performing a thorough inspection quickly before starting an excavator helps identify potential problems. As a result, it prevents them from developing into serious issues. The user should examine the excavator in some common areas, such as the hydraulic system to check for oil leakage, the rotation and flexion of the chassis and components, as well as the undercarriage. The engine, electric system, and other key parts should be checked too.
• Lubrication: Lubrication is essential to keep used excavators in proper working conditions. It reduces friction and wear between moving parts. Lubricating the tracks and drive wheels, bucket, arm and other components are important and necessary. Besides, the pivot points, hydraulic joints and seal points should also be lubricated.
• Fluid replacement: Regular replacement of fluids adds another essential maintenance task. It includes the lubricant as well as the hydraulic oil and coolant for the engine. The user should monitor fluid levels regularly. Also, they should change fluids based on the recommended schedule.

Scenarios of used excavators for sale in UAE

Used excavators perform crucial digging and demolition tasks in mining. They handle material with ease, from precious metals to heavy stone, and adapt to any soil condition with the right attachments.

In used excavator scenarios for sale in UAE, they load large haul trucks with aggregate, waste, or demolition debris. The powerful hydraulics push and pull heavy material. Recycling facilities rely on used excavators with long reach and sorting attachments to dismantle, sort, and process recyclable materials like metals, plastics, and paper. At landfills, excavators load waste into the ground and compact it to save space.

Used excavators break rock and concrete in quarries and construction with hydraulic breakers and buckets. In open-pit mining, excavators dig and remove surface earth to unearth ore. After mineral extractions, excavators fill and grade land for landscaping.

Farmers use small excavators with specialized attachments for crop management, irrigation, and livestock facility maintenance. They dig drainage ditches, ponds, trenches, and irrigation canals. Excavators can also assist farmers with landscaping and planting tasks.

Excavators in good condition are still used for mining operations looking to maximize their budget during excavator purchases. However, it is important that those purchasing used excavators have a full understanding of the operation requirements as well as maintenance of the mining sites before lifting the decision to purchase an excavator.Exploring this market can turn out to be fruitful if careful analysis is done by the buyer's end.

How to choose used excavators for sale in UAE

When purchasing a used excavator, buyers should conduct a thorough examination of the excavator before purchase. This will entail checking the excavator's maintenance history to determine if it has been regularly serviced. A well-maintained used excavator will most likely have many more years of efficient operation. Buyers should also get a report on the excavator's past projects. The project details will provide insight into the type of tasks the excavator has performed and if it has been strained or overworked. If the excavator has been used for digging frozen grounds or working at high altitudes, it may have special features that are not suitable for other projects.

Inspecting the physical condition of the excavator is crucial. Buyers should look for signs of wear and tear, such as cracks, rust, or leaks. They should also examine the undercarriage, tracks, bucket, and boom, as these are the most affected parts of an excavator. In addition, buyers should check the operational hours or mileage of the excavator. An excavator with low operational hours will most likely perform better than one with high operational hours.

Buyers should also check the excavator for abnormalities that may indicate a problem with the machine. They should pay attention to unusual noises, vibrations, or jerky movements. Ideally, buyers should take the excavator for a test drive before buying. This will give them a chance to inspect the machine thoroughly and familiarize themselves with its functions.
