determining the distance between
the pin centres, known as the pitch
extension (as pictured above).
“As the pin and pin bore wear
increases, so does the pitch
extension. This ultimately leads to
an inability to maintain track
tension and affects the
engagement between the crawler
shoe and sprocket, causing the
tracks to slip under high torque
loads.
“The Evolution shoes are showing
superior performance with the
average pitch extension wear rate
decreasing” said Nikolay.
Evolution crawler shoes are
manufactured from induction
hardened NiCrMo (Nickel
Chromium Molybdenum) cast
steel. The base metal enables the
crawler shoes to handle high
impact loads whilst the surface
hardening provides excellent wear
resistance in critical wear areas.
This has been an excellent
outcome for our customers and
has proven the superiority of the
Evolution product. We look
forward to showing other mines
the results and hope to increasr
sales within the region.
