Cast Lip Systems

CQMS Razer Cast Lip systems deliver productivity solutions for miners in all applications, from wheel loader to Hydraulic Excavators (100t to over 1000t).

The CQMS Razer (CR) Cast Lip range is designed with superior productivity features that deliver improved performance in all commodities. They are the lightest and strongest cast lips available in the market.

Whether you are targeting increased productivity, increased utilisation, improved cycle times or optimised fill factors, with our expert advice and support network, you can be sure our Cast Lip System is the right choice.

The CQMS Razer (CR) Cast Lip range is the largest in the market, with options available across four product groups:

All Cast Lip Systems are available in varying sizes, and specifications to drive productivity on your mine site, backed with an extensive range of G.E.T options to maximise performance.



DipperEdge™ has transformed the standard for rope shovel dippers.

Designed for the wide radius rope shovel dipper, the DipperEdge™ rope shovel cast lip system will increase productivity through a reduction of downtime, and safety risks, which can be associated with mechanically attached adapters and weld on stabilisers.

The DipperEdge™ will outperform the standard rope shovel cast lip, due to its integrally cast TRS35 class nose, alloy casting, and reduction in mass by up to 15%. This design feature allows for a higher capacity bucket that will increase lift volume and reduce dig energy.

The DipperEdge™ cast lip system includes hammerless locking rope shovel G.E.T, alloy casting, a smaller cross section with material distribution strategically placed, making it specially designed for productivity on your mine site.


The DecaEdge™ Cast Lip Range builds on the experience of our proven Stingray™ and RazerEdge™ cast lip systems.

Employing plane alignment, spade angle optimisation, and optimised material placement, the system removes outdated plate lip features, and delivers:

  • Up to 7% less downtime
  • 34% strength increase
  • 27% mass reduction
  • 30% reduction in digging force

DecaEdge™ lips can go for more than 12 months’ maintenance free on WA1200 class loaders.

Specifically designed teeth and shrouds mean that every time GET is replaced the underside wear package is refreshed, meaning that expensive wear blocks and wear packages are no longer required.

The DecaEdge™ range features both 10 station and 11 station cast lips, suitable for L1850 and L2350 class loaders. CR is the only manufacturer to offer a range of cast lips for mining ultra class wheel loaders in the world.

The RazerEdge™ Cast Lip range is designed to replace outdated plate lip systems, on 200t to 500t excavator machines. These are the only proven cast lip systems for under 500t machine, delivering maintenance and productivity improvements for 5+ years in all types of applications, including Iron Ore and Coal in Australia, Coal in Indonesia, Silver in America and Gold all over the world.

RazerEdge™ cast lips are specifically designed to remove the weaknesses that are associated with weld on adapters and G.E.T. By removing the weld on adapters, RazerEdge™ lips are almost 30% stronger. This offers significant savings in maintenance hours and costs, but also delivers an opportunity to increase machine availability significantly.

RE1522 Cast lip system

CR introduces the RE1522 Cast lip system into the RazerEdge™ range as part of the ever expanding cast lip offerings. The RE1522 is the smallest cast lip ever designed by CQMS Razer suited to 100t-140t class machines. The RE1522 boasts superior strength increases over conventional plate lip installation. It provides increased reliability with significant improvements in maintenance and associated downtime related to G.E.T. changeouts.

The RE1522 single piece cast lip removes excessive heat effected zones, sharp transitions and uncontrolled weld stresses by eliminating them altogether.

The design significantly reduces risks associated with G.E.T. changeouts and improves maintenance practices by eliminating requirements for hot work on continual repair welds.


The Stingray™ Cast Lip range is suited for excavator machines from 500t class and up. These are fitted across the globe on some of the largest excavators in the harshest conditions, including Platinum in South Africa, Iron Ore in Russia, Copper in South America and Magnetite in Australia.

Our Stingray™ Cast Lip system was designed in collaboration with some of the world’s leading OEMs; including CAT, Liebherr, and Hitachi.

Plane alignment and Angled Shrouds ensure that Stingray™ cast lip systems deliver:

  • 10% productivity gains
  • >6% strength increases
  • 8% mass reduction
  • 10% lower penetration forces

* Validated against Plate lip on Hydraulic Excavator & Face Shovel Wheel Loaders for both DecaEdge™ and Stingray™
