Mod-01Bucket fabrication

Two ways we modify
an excavator bucket

The bucket that came with a used machine rarely matches the next job. Buyers ask for two changes — a larger-capacity bucket to move more per pass, or a heavy-duty bucket built to survive tougher ground. Both are re-pinned and bushed to fit your exact machine.

A

Larger capacity most common

A wider, higher-volume bucket so the machine moves more material per pass in loose soil, sand, and general earthmoving.

B

Heavy-duty rock & demo

Reinforced shell, heavy wear plates and rock teeth for demolition, quarry, and abrasive ground where a standard bucket wears out fast.

Mod-02Undercarriage · mini excavators

Rubber tracks for
finished surfaces

Steel tracks are great for raw ground but destructive on pavement, paved yards, indoor floors, and landscaping. We convert the undercarriage to rubber tracks or fit bolt-on rubber pads over the existing steel links — sized to your specific mini model.

+Protects surfaces

No cracked pavement or torn-up floors the way steel grousers cause.

+Quieter & smoother

Lower vibration and noise for urban, utility, and landscaping work.

+Two options

Full rubber-track conversion or bolt-on pads — by site and budget.

+Undercarriage check

Sprockets and rollers inspected during the swap.

Mod-03Hydraulic systems

Full hydraulic
system modification

Most used excavators leave the factory plumbed only for the bucket cylinder. To run aHamer hydraulic drill, rock breaker, auger, compactor, or hydraulic thumb, the machine needs auxiliary circuits, control valving, and correctly tuned flow at the end of the arm.

We engineer the complete circuit in-house — piping, valve sections, in-cab controls, coupler-ready plumbing — set to the attachment's flow and pressure spec, then load-tested so it performs without overheating or starving the main circuit.

Fig. C — Hamer drill · aux circuit

01

Auxiliary & breaker lines

Single- and double-acting steel and hose runs along the boom and arm to feed breakers, drills, augers, and compactors.

02

Control valve & pilots

A dedicated valve section with pilot or proportional electric control — the operator runs the tool from the joystick.

03

Flow & pressure tuning

Relief and flow set to the attachment's required LPM/GPM and bar, so a Hamer drill runs to spec without overheating.

04

Coupler & thumb circuits

Dedicated low-flow circuits with holding valves for safe, drift-free clamping.

05

Pumps, cylinders & hoses

Main pump pressure verified, tired cylinders resealed, aged hoses replaced, oil & filters renewed.

06

Load test & report

Function-tested under load with the attachment fitted — documented with photos and video.

Running a Hamer drill or another powered attachment?

Send the attachment model and its flow/pressure spec — we'll confirm the hydraulic conversion your machine needs.

Mod-04Quick couplers

Swap attachments
in under a minute

Without a coupler, changing from bucket to breaker means hammering pins on the ground — 20 to 30 minutes each time, twice a day. We fit a quick coupler (quick hitch) matched to your machine's pin diameter and stick width, so the operator swaps attachments from the cab and the machine keeps earning.

A

Mechanical pin-grabber budget

A robust wedge-lock coupler operated at ground level. No hydraulics needed — a simple, low-maintenance upgrade for machines that change tools a few times a week.

B

Hydraulic quick coupler most popular

Fully hydraulic pin-grabber with in-cab switch, dual safety lock, and check valves that hold the attachment even if pressure is lost. Coupler circuit plumbed as part of the install.

Mod-05Paint & identity

Your fleet color. Your logo.
Any RAL code.

A repaint isn't cosmetic — it's corrosion protection and brand presence on site. Every machine is sanded back, primed, and finished in two-component polyurethane topcoat, then your logo is sprayed through stencils or applied as cut vinyl decals.

Preview — stylized

Color: Safety Yellow

Or send any RAL / Pantone reference — we mix to code.

1

Surface preparation

Old paint and rust removed by sanding and spot-blasting; dents filled and panels straightened before any primer goes on.

2

Epoxy primer + 2K topcoat

An anti-corrosive epoxy base followed by two-component polyurethane in your exact color — mixed to any RAL or Pantone reference.

3

Logo spraying & decals

Send a vector file (AI/PDF/SVG) — we spray through cut stencils or apply UV-stable vinyl decals on the house, counterweight, and boom.

4

Safety markings preserved

Warning decals, rating plates, and reflective strips re-applied after paint so the machine stays compliant on site.

ProcessSpec to shipped

From spec to shipped
in four steps

01

Tell us the job

Share the machine, the material or surface, and any attachment you plan to run.

02

We quote the mod

We confirm parts, fitment, and lead time, then quote the modification with the machine.

03

Build & test

Our workshop completes the work and function-tests it, with photos and video for you.

04

Ship ready to work

The machine loads for export already configured — no local shop needed after import.

Work order — final line

Tell us what the machine
needs to do

A bigger bucket, rubber tracks, a full hydraulic conversion, a quick coupler, or a repaint in your company colors — we modify the machine in China so it arrives job-ready.
