The KRC 500 S has been specifically developed for the installation of large modular track panels. The methodology is based on the use of two KRC 250 cranes with an integrated wagon creating a fixed-formation system capable of lifting panels up to and including those for ‘G’ switches.
The use of cranes in a tandem lifting arrangement usually demands a 50% down-rating to mitigate against one crane overburdening the other when a load is suspended between them. SB Rail’s patented TTS system reduces this down-rating requirement to just 10%, allowing heavier loads to be lifted by two of our cranes in unison.
The KRC 500 S is enabled by our patented robotic arm together with load slide prevention technology to ensure stringent control during tandem lifts. The technology allows operators to retain complete control over loads and tension arising from the two point lifting system.
Through graduated audio-visual warnings connected to the TTS, each operator is able to work in unison to manage tension on the load within safe working limits.
The robotic arm attached to each jib rigidly attaches loads with a shackle preventing sway. The absence of ropes and pulleys ensures loads are no longer subject to uncontrolled movement and completely resistant to load slide in an emergency stop situation.
