RTC – Rope Tension Control
SRC – Synchronised Rope Control

• More cost-effective in operation thanks to improved load cycle time
• Improved operator friendliness – leaving the operator free to
concentrate on crane movements
• Avoidance of damage to the rope or load

The Rope Tension Control (RTC) and the new Synchronised Rope Control (SRC) are further innovations from PALFINGER with a clear focus on optimising customer benefits in terms of cost-effectiveness, operator comfort and safety.

The RTC is an automatic rope tensioning device that makes it easier to fold and unfold the crane with the rope reeved in and the fly-jib (additional knuckle boom) mounted.

If any crane movements are performed that affect the rope length, the innovative system electronically and fully automatically adjusts the rope length to match. The operator no longer needs to worry about constantly adjusting the reeved-in rope. Instead, the RTC performs this task automatically, and, as a result the rope and pulley head can remain permanently mounted on the crane.

But beyond this, hook operation with a fly-jib and reeved-in rope is also possible. The time-intensive process of disassembling the rope is no longer necessary, making this the ideal solution for frequent setup changes and for short assignments.

The SRC system maintains a constant distance between the pulley head and the hook block during operation of the rope winch. Similarly to the RTC, the system automatically adjusts the rope length. The key advantage in practice is that loads can be traversed horizontally at a constant height without the operator having to adjust the rope winch. In addition, it is also possible to traverse the load at a constant angle on the rope winch. Work in buildings or tight spaces become child’s play, and difficult operations like overcoming building contours during roofing work are also made significantly easier. This advantage is particularly valuable in terms of ease of use for the operator, and it also noticeably improves the efficiency of any assignment. Inaddition, the risk of damage to the rope and load, but also collisions between the hook block and the pulley head will be avoided.

Sensors in the roller head detect the movement and forward the signals directly to the Paltronic 150. If the SRC is activated, it automatically makes the necessary adjustments to ensure that the distance between the pulley head and the hook block remains constant during any crane movements that lengthen or shorten the rope length. If the knuckle boom or fly-jib is lowered, the SRC again adjusts the rope winch to keep a constant distance between the lower block and the roller head.

These innovative systems are available for SH crane models (SRC from PK 10002 SH and RTC from PK 27002 SH).
