MASPRO Re-engineers TFX Feed System to Address Recurring Hydraulic Cylinder Failure
A MASPRO case
study involving TFX hydraulic feed cylinders on underground development jumbos shows the value of asking that question. Premature cylinder
failure was traced to a specific internal
condition: air encapsulation between the floating piston and piston rod, driving unplanned downtime, increased replacement frequency,
maintenance cost and personnel exposure.
Rather than continue supplying replacement cylinders exposed to the same failure mechanism, MASPRO reviewed how the TFX feed system was functioning under operating conditions and redesigned key elements of the assembly: transfer tube positioning, internal cylinder geometry and the air-management pathway. The redesigned cylinder was trialled and validated in active development fleets.
Across
six development jumbos covering 12 booms, cylinder usage reduced by 25% over
the 12-month measurement period, with a 54% cost saving compared with
original equipment manufacturer supply. Under MASPRO's Service Exchange
Program, cylinder consumption reduced by 66%, with a 61% cost saving compared with the previous procurement
model.
Performance Re-engineered, Not
Reproduced
MASPRO is an Australian-owned engineering and manufacturing company
specialising in precision-engineered aftermarket components for underground and
surface hard-rock mining equipment.
MASPRO's approach to Performance Re-Engineering focuses on
understanding the failure mode behind a component rather than simply
reproducing the component exposed to that failure. In the TFX feed system, that
approach led to design changes that reduced cylinder consumption under the
operating conditions documented in the case study.
MASPRO
will bring this perspective to Electra Mining Africa 2026, where the team will be available to discuss
hydraulic, wear and structural failure challenges across underground and
surface mining applications.
Visitors can
meet MASPRO in Hall 3, Australian Pavilion, Stand D15-B.
