Undercarriage Measured
Percentage wear per component with remaining life projection turns the largest running cost on a tracked machine into a planned expense.
To put the right machine on the right job, specified against real material, access and transport conditions rather than against a sales target.
Who We Are
COT Sverige supplies, rents and services construction and earthmoving equipment: excavators across the size range, wheel loaders, dozers, articulated dump trucks, graders, compaction equipment, skid steers, compact track loaders and attachments. Our support covers field and workshop service, planned maintenance contracts, component rebuilds for engines, transmissions, final drives and hydraulics, undercarriage inspection and supply, parts, telematics monitoring and operator familiarization. We also sell inspected used equipment with its service history disclosed, and offer rental to cover peaks, trials and breakdown gaps.
Contractors around work with COT Sverige because machine selection and uptime decide whether a job makes money. An excavator a size too small runs at full load all day and costs fuel, wear and cycle time. One a size too large may not fit the site access or the transport permit. Material density, haul distance, bench heights and truck matching all affect the right answer. We ask about the work being won rather than the work already owned, specify accordingly, then back the machine with field service, measured undercarriage inspections and telematics monitoring that flags developing problems while they are still cheap.

Compliance
Used machines are sold with their known faults disclosed in writing.
Telematics monitored, not just installed and forgotten

Our Mission
To put the right machine on the right job, specified against real material, access and transport conditions rather than against a sales target.
Sectors
We sell new and used machines, rent, and maintain fleets under contract.
Client Feedback
They told us our loaders were a size too small for our trucks. Correcting that cut our cost per tonne more than any other change we made that year.
Measured undercarriage wear turned a surprise expense into a planned one. Our cash flow planning improved as much as our machine availability.
The oil analysis caught a final drive before it let go. We exchanged it on a Saturday instead of losing the middle of a week.
Tell COT Sverige about the material, haul distances and site access, and we will specify against the work rather than the brochure.
Downtime on a critical machine stops a crew, not just a machine. Our field service units carry parts and diagnostic equipment to finish repairs on the first visit wherever possible.
Our Advantages
Percentage wear per component with remaining life projection turns the largest running cost on a tracked machine into a planned expense.
Oil sampling across engines, transmissions, final drives and hydraulics catches failures while they are still repairs rather than rebuilds.
We ask about material, haul distances, access and transport limits rather than simply matching whatever machine you currently run.
Service units carry parts, diagnostics and hydraulic capability, because a return trip for a component costs a crew far more than the part.
Fault codes, utilization and idle time are reviewed and acted on rather than left generating reports nobody reads.
Hours, service history, undercarriage condition and known defects are stated, because the alternative destroys trust permanently.
Alerts are triaged by our service team with action recorded, instead of being forwarded to a customer who has no time to read them.
Inspection findings and known defects are written into the sale, because a used machine sold quietly comes back as a warranty argument.
Service vehicles are stocked and technicians are model trained, so most breakdowns are resolved without a second trip for parts.
Our Services

Measured undercarriage wear inspections with percentage wear reported per component, remaining life projection and replacement planning, plus supply and fitting. Undercarriage is the largest running cost on a tracked machine and the most straightforward to manage once it is measured.
Request a Quote
Short and long term rental for project peaks, machine trials, specialist attachments and cover during repairs, with maintained equipment and transport arranged. Rental also lets a contractor prove a machine type on their own material before committing capital.
Request a Quote
Rebuilds of engines, transmissions, final drives, hydraulic pumps, motors and cylinders, plus exchange units to minimize downtime. Rebuilding a component to published specification with documented testing frequently costs substantially less than new while restoring full service life.
Request a Quote
Inspected used machines with service history, hours, undercarriage condition and known defects disclosed, plus component condition assessment where major rebuilds have been carried out. Used equipment sold without disclosure is how customers lose confidence in a dealership permanently.
Request a Quote
Supply of excavators, loaders, dozers, dump trucks, graders, compaction equipment and compact machines, specified against material density, haul distances, bench heights, truck matching, site access and transport weight limits. A machine a size wrong in either direction costs money every working day.
Request a Quote
Scheduled servicing with oil and coolant sampling, filter analysis and inspection reporting, timed around your project schedule. Oil analysis on engines, transmissions, final drives and hydraulics catches developing failures while they remain repairs rather than rebuilds.
Request a Quote
Mobile service units with parts, diagnostic equipment and hydraulic capability to complete repairs on site, covering engines, hydraulics, electrical systems, transmissions and final drives. A second trip for a part turns a half-day repair into a lost week for the crew depending on the machine.
Request a Quote
Buckets, breakers, grapples, rippers, compaction and specialist attachments matched to machine hydraulics and application, genuine and quality aftermarket parts, and telematics monitoring with alerts on fault codes, utilization and idle time.

Used machines are sold with their known faults disclosed in writing.
Our Process
We discuss the material, production targets, haul distances, bench and loading heights, site access, transport limits and the duty cycle the machine will actually see.
Machine size, configuration, attachments and tyre or undercarriage options are recommended with the reasoning stated, including rental or used alternatives where they suit better.
Equipment is delivered with operator familiarization, telematics set up, maintenance intervals established and fluid sampling baselines captured.
Planned maintenance runs to schedule with fluid analysis and inspection reporting, undercarriage wear is measured periodically, and telematics alerts are reviewed and acted on.

Undercarriage is the largest single running cost on a tracked machine and the easiest to manage. Measured wear inspections turn a surprise bill into a planned one.
Projects & Case Studies

A contractor considering a different machine class trialled it on rental in their own material and site conditions before committing. The trial changed the specification they ultimately purchased.

A quarry running loaders a size too small against their haul truck capacity was mismatching loading passes. Correct machine sizing cut cycle times and fuel per tonne, and the loading operation stopped being the production bottleneck.

Measured undercarriage inspections across a tracked fleet produced percentage wear and remaining life per machine. Replacements moved into planned windows and the surprise bills that had been disrupting cash flow stopped.

Wear metal trends in a final drive sample flagged a developing failure. The unit was exchanged during a planned weekend rather than failing mid-week, saving the crew several days of lost production.

Questions & Answers
It is useful only if someone acts on it. Fault codes, utilization and idle time data reveal developing faults, underused machines and operator practices that waste fuel. We review the data with you rather than installing it and generating reports nobody opens.
Because it wears continuously and the components are substantial. It is typically the largest running cost on a tracked machine. It is also the most manageable, since measured wear inspections let you plan replacement rather than absorbing a surprise bill mid-project.
From the work rather than the brochure. Material density, haul distances, loading heights, truck matching, site access and transport weight limits all constrain the answer. A machine a size too small runs at full load constantly; one too large may not reach the site legally.
Wear metal trends in engines, transmissions, final drives and hydraulics reveal developing failures well before symptoms appear. That converts a catastrophic failure mid-project into an exchange scheduled into a weekend, which is a very different cost.
Yes, including hours, service history, undercarriage condition and known defects. A used machine sold with problems concealed creates a dispute that costs more than the margin on the sale, and it ends a customer relationship permanently.
On major components frequently yes, and a rebuild to published specification with documented testing restores full service life. Where a component has been run to destruction and the housing or case is damaged, replacement is the honest answer and we will say so.

A visible skip-to-content link, keyboard-operable navigation and menus, and focus styles that remain visible when navigating without a mouse.
Text and interface colors checked for contrast against their backgrounds, layouts that reflow at narrow widths and support browser text resizing without loss of content, and descriptive alternative text or accessible labels for images and icons that carry meaning.
Form fields with programmatically associated labels, required fields identified in text rather than by color alone, and link text that makes sense out of context.
Some decorative illustrations are presented without detailed descriptions because they convey no information beyond the surrounding text. Documents published in formats such as PDF may not meet the same standard as the website itself; we will provide an accessible alternative on request.
This website is designed to work with current versions of major browsers on desktop and mobile, used together with the assistive technologies available on those platforms. It may not perform as expected in browsers that are no longer supported by their vendor.
