Key Specifications and Features of Track Excavators
A track (crawler) excavator is a hydraulically powered machine used for site grading, excavating, and lifting that hangs on moving tracks. Numerous interdependent systems, including the engine, the hydraulics, the chassis, boom, and controls, affect how well it performs. The objective here is to understand how each specification affects real-world capability.
Operating Weight
The machine’s total weight when operating (in kilograms) is the overall mass of the track excavator. Although heavier machines often provide more stability and digging force, they also come with increased ground pressure and transportation expenses. Select weight in accordance with transit restrictions and site terrain.
Powerful Engine
The ISO-recommended engine horsepower at a specific rpm. Higher power supports Better hydraulic output and ongoing efficiency under load. However, travel speed, torque curve, cooling, and fuel efficiency are also essential factors.
Hydraulic System
The amount of hydraulic fluid the pumping mechanism supplies is the pump’s mechanical flow (l/min or gpm). Optimum functioning pressure, often known as system value (bar or psi).
Flow determines the speed at which attachments, movement, and the arm/boom work. The force that pistons and motors can use is related to pressure—higher pressure results in greater force; higher flow results in faster cycle periods.
Digging Forces
These are the loads that the bucket or arm can apply to break material loose; they are expressed in kN or lbf. Why they are essential shows clearly how effectively the machine can manage big loads, stones, or compacted dirt. Manufacturers know which standard is being utilized and frequently reference “ISO” and “SAE” breakthrough numbers.
Bucket Capacity
The bucket capacity (m³ or yd³) determines the material carried per cycle. The second-hand track excavators for sale in Houston, TX, have real-time reach and strength to the bucket to perform the intended operations.
While arms with more length can reach deeper and farther, they can also lessen braking force; bucket size strikes a balance between possible hydraulic/breakout force and cycle time.
Maximum Digging Depth
The manufacturer’s boundaries determine the maximum depth, horizontal reach, and cutting length. Ensure the equipment can dump onto containers at the site arrangement or reach the necessary depths.
Swing Torque and Speed
The torque available and the uppermost structure’s rotational speed (rpm) influence cycle duration. Swing speed influences cycle duration, while elevated rotating torque enhances turning under load (helpful when lifting laden buckets).
Drawbar Pull and Travel Speed
The machine’s travel speed (km/h or mph) indicates how quickly it moves on tracks. Drawbar pull (kN) is a powerful force used to operate on steep gradients, drag, or push loads. It is vital for pushing supplies, traversing slopes, and moving about the site.
High Ground Clearance
It is measured in (kPa or psi) divided by the area of the track footprint. A raised channel from ground level is constructed to reduce the impression of the track excavators’ weight on the terrain surface. Lower ground pressure lessens sinking on soft ground, vital for vulnerable surfaces.
Attachments Used with Crawler Excavators
The most popular track excavator attachments and information on their uses, technical aspects, and functionality. Frequently used with careful selection to help them make well-informed decisions.
- Standard Bucket
The most fundamental and popular attachment. It is intended for excavating and transporting light rock, sand, clay, gravel, and soil.
- Technical Specifics:
Has teeth made of robust steel that can penetrate compacted soil.
Durability is increased by blunt edges and strengthening side walls.
Various widths (usually 18 to 48 inches) are available based on the necessary trench or digger width.
- Uses:
Excavating a foundation
Utility drilling for gas, sewage, and water lines
Preparing the site and doing general demolition
- Grading and Ditching Bucket
Designed to clean up, level, and shape work instead of excavating.
- Technical Specifics:
They are usually 48–84 inches broader than digging buckets.
Features a toothless, smooth edge for a neat finish.
Frequently features a flat bottom to produce consistent slopes and gradients.
- Uses:
Complete grading following bulk excavation.
Projects involving greenery
Washing and forming waterways or ditches
- Breaker Hydraulic Hammer
Breaks through concrete by converting hydraulic force into damaging energy.
- Technical Specifics:
Distributes blows with a BPM (force of blows per minute) measurement.
It demands high hydraulic pressures, circulation, and connectivity with the hydraulic system.
For urban developments, specific models incorporate sound suppression.
- Uses:
Recycling of pavement and asphalt
Mines and quarrying activities
Demolition of roads and bridges
- Hydraulic or Mechanical
Accompanies a bucket to grasp, lift, and position large or unusual items.
- Technical Specifics:
Secured in place, the artificial thumb is perfect for mild touch.
The hydraulic thumb made controlled grasping possible, which worked with the unit’s hydraulics.
Heavy-duty steel was used in its construction to support heavy lifting.
- Uses:
Managing building debris, lumber, and rocks
Demolition and property clearing
Sorting and positioning of materials
Tasks related to vegetation and forestry
- Grapple
Handles big, loose, or heavy objects like a claw.
- Technical Specifics:
Both stationary and revolving variants are available.
Strong, controlled grasping is made possible by designs with two or more tines.
In confined areas, hydraulic rotation improves accuracy.
- Uses:
Cleaning of wreckage from demolition
Woodworking and forestry activities
Processing of garbage and leftovers
Functions in recycling yards
How to Select Used Track Excavators
When choosing a used track excavator, consider the machine’s physical condition, service history, and suitability for your project requirements. You shouldn’t merely consider the machine’s age or cost. When purchasing a used track excavator, follow this expert, detailed information to help you make an informed choice:
Identify Your Requirements
Ensure you know precisely who you’ll be utilizing the track excavator before inspecting it.
- Type of Application: infrastructure work, removing obstacles, deconstruction, excavating, or earthmoving.
- Excavators Class: There are three machine classes: Small (up to 6 tons), medium-sized (7–25 tons), and powerful (25+ tons).
- Digging Depth: Comply with the requirements of your project.
Hydraulic capacity is crucial if you intend to employ extensions like hammers or augers. The most popular size for general construction is a 20-ton excavator; however, mining may require larger machines, while residential tasks may require smaller ones.
Examine the Undercarriage
Up to 50% of the machine’s maintenance expenses go toward the undercarriage, so its health is essential.
Look for:
- Check for splits that are worn out on the track chains and pads.
- Idlers and rollers should spin quietly and smoothly.
- Teeth that are hooked or sharp suggest significant wear and may need to be replaced.
- Tight or loose tracks may indicate a need for maintenance.
Engine and Hydraulic System
A dependable excavator is built on a solid engine and hydraulic system.
Check for:
- Engine: Look for smooth start-up, oil leaks, and smoke color (black indicates fuel problems, blue indicates oil burning, and white indicates coolant problems).
- Hydraulic system: Check fittings, cylinders, and hoses for leakage. Regulate the boom, stick, and bucket to ensure smooth action.
