Crawler Excavators - Earthmoving Machinery
A hydraulic crawler excavator is an earth-moving machine that uses a bucket to excavatematerials above or below the bearing surface and loads them into.

Operator comfort is treated as a productivity feature: pressurised cabs, air suspension seats, low-effort pilot controls and clear sight lines measurably extend productive shift hours.
Productivity on earthworks is decided by the weakest link in the loading and hauling chain. HAMAC earthmoving machinery covers that chain with wheel loaders, backhoe loaders, crawler excavators, skid steer loaders and compact track loaders, each specified for the machine you already own rather than sold from a catalogue.
Most enquiries we receive start after a fleet problem — a pump that loses pressure on long booms, a mixer whose drum liners wear prematurely, a batching plant whose weighing tolerance drifts. Each of those has an engineering answer, and that answer belongs in the design stage rather than in the warranty claim.
Key Advantages of Crawler Excavators
Field-serviceable design
Ground-level filters, grouped grease points and swing-out coolers reduce daily service time.
Attachment-ready
Hydraulic quick couplers accept forks, breakers, augers, sweepers and grapples.
Parts and training support
Common wear parts ship fast and operator training is part of every delivery.
Strong hydraulic circuits
Load-sensing hydraulics allocate flow to whichever function needs it, keeping cycle times predictable.
Matched to the haul fleet
Bucket and breakout force are selected so trucks are loaded in the planned number of passes.
Protected against dust and heat
Heavy-duty air filtration, oversized radiators and reversible fans suit tropical and dusty sites.

Typical Applications
The applications below reflect the situations in which HAMAC customers most commonly deploy it.
Building foundations
Basement excavation, footing work and site clearance
Snow and municipal work
Snow blades, sweepers and material spreading
Road construction
Excavation, trenching, backfilling and material handling
Ports and stockyards
Handling bulk material with high-tip buckets and grapples
Aggregate and quarry loading
Feeding crushers and loading haul trucks continuously
From Enquiry to Commissioning
Six defined stages, each with named deliverables, so nothing is left to interpretation.
Requirement study
We start with your mix design, hourly output target, aggregate size, jobsite power supply and site layout — not with a catalogue page.
Scheme design
Our engineering team issues a layout drawing, foundation loads, power requirement and an equipment list matched to the target output.
Quotation & contract
A fixed specification quotation with clear technical annexes protects both sides; no vague "standard configuration" wording.
Production & inspection
Weekly production photos, welding and pressure test records, plus third-party inspection if your project requires it.
Delivery & installation
Container or break-bulk shipment, then on-site supervision of assembly, alignment, calibration and dry-run.
After-sales
Remote diagnostics by video call, spare parts dispatch within 48 hours for stocked items, and periodic return visits.
Frequently Asked Questions about Crawler Excavators
How do you handle warranty?
12 months or 2,000 operating hours, whichever comes first, with parts dispatched within 48 hours from stock.
Which model replaces my ageing machine?
Give us the current machine make, bucket size and cycle time; we will propose the closest HAMAC equivalent with a duty comparison.
What emission standard applies?
We supply Stage II for most African and Asian markets, EPA Tier 4 Final or Stage V units where regulations require it.
Can operators be trained on delivery?
Yes — commissioning includes operator familiarisation and a maintenance briefing for your mechanics.
Are attachments included?
Standard bucket is included; specialised attachments are quoted separately and can be crated with the machine.
