Product presentation: Drum coupling TTXL
09.01.2023
The new TTXL drum coupling is made of forged rings and guarantees high performance ranges as well as improved operational safety due to its optimised internal design. Despite mounting dimensions are almost worldwide standardized, also special versions are available.
The drum coupling type TTXL is a further development of the RTT, NTT, TTX and TTXs versions, which have been proven successful over many years.
The new development exhibits an increase in capacity, accompanied by significantly improved operating security and also meets with customers demands for higher capacities smaller weights and installation space.
The connection dimensions ensure the possibility to replace former types.The transmission of force within the drumcoupling takes place through positive locking. Hardened barrel rollers, placed in the holes formed by the two circular gearings, are used as force transmitting elements. The barrel rollers are driven axially. The cover and housing, combined with the seals, prevent both the ingress of foreign bodies and the leakage of lubricant. The torque is transmitted to the rope drum via the flattenings on the outer diameter of the coupling housing and via the friction between the coupling housing and the flanged wheel. The new design is suitable for absorbing radial forces with simultaneous transmission of torques.
Wear indicator
A pointer attached to the outer cover and a corresponding milled marking on the coupling hub enable the wear and the axial position of the coupling housing to the coupling hub to be checked from the outside. It is not necessary to dismantle the clutch for this purpose. An automatic wear indicator is available as an option. Here, a signal (e.g. to the crane control) is emitted via a sensor attached to the gearbox at approx. 80% wear.
