Wheel-base reductions
Shortening cab-chassis wheel-bases to suit pump, mixer and transporter builds – engineered and certified for NZ compliance.
For more than 20 years PS Equipment has specialised in chassis modifications for concrete boom pumps, truck-mounted line pumps, slide-deck transporters and mixers. From wheel-base changes to full concrete pump re-trucking, our team builds affordable, versatile solutions that add enduring quality to your machinery.

Our custom body builders specialise in repurposing used concrete boom pumps and fitting them to new truck chassis. It's a proven, cost-effective route to a modern, compliant pump truck – without replacing the pump itself.
We also handle wheel-base reductions and extensions, concrete pump re-trucking, and truck body modification work to suit whatever you're building. Every job is certified by our heavy vehicle engineer and concrete boom certifier, so compliance requirements are covered from the outset.
Whether you're preparing a new cab-chassis for a specialist body, refreshing an existing pump, or need repair work you can rely on, our team delivers high-quality custom solutions at an affordable price.
