Concrete Mixer Arm Selection & FAQ
What shaft bore options are available for VOTNE mixing arms?
We offer square bore, hexagonal bore, and round keyway mixing arms to fit standard and custom concrete mixer drive shafts.
How are VOTNE mixing arms manufactured to prevent breakage?
Our mixing arms are cast using high-strength ductile iron and heat-treated alloy steel, followed by precision CNC machining and non-destructive testing to eliminate internal casting defects.
What is the difference between left-side, right-side, and central mixing arms?
Left and right side arms feature specific blade mounting angles to direct boundary material inward, while central arms provide maximum torque and fluid movement across the mixer center.
Can VOTNE supply complete mixing arm assemblies with hardware?
Yes, we supply mixing arms individually or as complete sets including high-tensile locking bolts, wear guard covers, and blade mounting brackets.
What maintenance signs indicate a concrete mixer arm needs replacement?
Inspect for excessive surface gouging, bore keyway wear, or hairline cracks near stress points; replacing worn arms prevents shaft misalignment and catastrophic mixer failures.
