Pads and over-pads
Illustration based on an existing product.
The pad is part of the steel track.
The over-pad bolts on top so as not to mark the ground:
they are two different parts, and they are often confused.
Other names for this part: track pad, rubber over-pad, track shoe, shoe.

What it is for
Right: with bare steel pads, the asphalt is scratched and gouged.
What sets them apart:
they are chosen by the pitch of the chain and the width of the pad, never by the tonnage.

The pad is the steel shoe bolted onto each link.
It is changed one at a time:
a bent pad does not condemn the chain.
The over-pad is an added part, in rubber, that covers the steel pad.
It turns a steel-tracked machine into one that is acceptable on asphalt, a slab or paving — for the length of the job, then it is taken off.
A worn over-pad is worse than no over-pad: when the rubber is eaten away down to the fixing steel, it is the steel that touches the ground, and it scratches more than a bare pad.
They are checked job by job.
On which machine?
Pads and over-pads are fitted as original-equipment replacements, on the undercarriage.
These parts suit all classes, depending on the chain pitch.
On a machine from 13 to 20 t: over-pads for chain at 171 or 175 mm pitch.
On a machine from 20 to 22 t: over-pads for chain at 203 mm pitch.
What the tool does
Steel pads come with a single, double or triple grouser, from 220 to 1 200 mm wide.
As for over-pads, the widths are 300, 350, 400, 450, 500, 600, 700 or 800 mm.
An over-pad weighs 2 kg at 300 mm, and 12 kg at 700 mm for a chain at 203 mm pitch.
What is needed on the hydraulic side
These parts need no hydraulic connection: they are part of the machine.

What determines the choice
-
01 — The pitch of the chain
It governs everything.
An over-pad is not chosen by the tonnage of the machine but by the pitch and the width of the pad it has to cover. -
02 — The method of fixing
Bolted through the pad, clipped on, or mounted with a clamp:
the bolted one holds better, the clipped one goes on faster. - 03 — How long the need lasts A two-day job in a town centre does not justify the same equipment as a year in an urban area.
-
04 — The thickness of the rubber
It is what gives the service life.
A thin over-pad protects the ground just as well — for less time.
What is checked before ordering
- Record the pitch and the pad width — the over-pad is ordered on those, never on the machine model alone.
- Count the number of pads per track:
over-pads are sold as a complete set, and two sets are needed. - Allow for the fitting time:
reckon on half a day for two people on an 8 t machine, more if the bolts have seen some life. - Check the ground clearance after fitting — an over-pad adds a few centimetres, which changes what the machine can climb over.
