Engcon, the world’s leading tiltrotator manufacturer, has announced that the new EC233 series tiltrotator is in full production. With a break torque of 340 kNm it will be the market’s most powerful tiltrotator built for excavators up to 33 tonnes. The EC233 replaces Engcon’s EC30, which has been loyally serving Engcon’s customers since the mid 90’s.
“Everything from first prototype to full series production has gone very well,” says Fredrik Jonsson, Development Manager at Engcon. The product development cycle was focused on destructive tests where both mountings and connectors were exposed to extreme overload in laboratory environments. Testing then continued on large excavators in the field.
Jonsson explains how it works: “We always start by putting our test products under huge stres in a powerful hydraulic rig where we overload the unit in a controlled environment. It gives us a clear picture of where any structural flaws may exist”.
“Even though we have subjected the equipment to some serious pressure in a laboratory environment, things happen in real life that you can’t always anticipate in the lab. It’s everything from changing temperatures to an infinite number of stresses that can’t be simulated easily, but the EC233 has sailed through development” said Fredrik Jonsson.
