Radlinger Maschinen-und Anlagenbau, part of the Radlinger group, a leading German construction equipment manufacturing and contracting firm, has boosted its range of innovative products with the patented tilt motor.

The design principle of the Rädlinger tilt motor – available in an extensive array of sizes and designs – facilitates high-precision tilt motion in the angling of buckets of excavators and has many beneficial features: High-tensile alloys have been used in body parts to ensure compactness and rug-gedness; hydraulic hoses are connected directly into the tilt motor head, eliminating downtime, due to kinking and tearing off; parts susceptible to wear and tear, such as hydraulic cylinders, pins and bushings are dispensed with, ensuring long-term durability of the machine; force-feed lubrication of the entire system by grab swing mechanism oil, reduces the need for maintenance; and hardened and amply dimensioned components in its body design, ensures years of wear-free operation with high performance and low fatigue.
In addition, the bolts allow suspensions and/or work tool bodies to be interchanged; the unit offers a favourable price-to-performance ratio in the medium and long-term run; the machine operator derives exceptional motivation from the high-precision tilt motion and absolute reliability under all operating conditions.
The Radlinger tilt motor operates on the dual diversion principle of the left-hand/right-hand helical teeth. Over and above the standard angle of rotation of 90 degrees, it can be customised to provide all intermediate angles of rotation up to 180 degrees in an infinitely variable manner.
Currently, the spectrum of output ratings (at 150 bar operating pressure) starts with 6,900 Nm in the five-tonne excavator class and goes as far as 33,000 Nm in the 40-tonne class. “This allows even extremely hard jobs to be performed in the field without any difficulty,” says a company spokesman.
The Rädlinger tilt-motor uses high-grade and high-tensile steel or nodular cast iron exclusively as the raw materials making up the body parts. All mated sliding pairs are long-term nitrided or hardened and also force-feed lubricated, he concludes.
