CAS

Rope angle limit sensor & controller

CAS is a high-performance inclination sensor and controller that can be connected to CLL, CLB or CED units to prevent lifting at prohibited rope angles on electric cranes and to give an audible warning.

360°X/Y cone control

Overview

Operating principle: the system calculates the angular difference between the X and Y axes and defines a cone-shaped zone in which the working limits and warnings of the lifting system are set. It can be configured to protect X, Y, X and Y, or the resulting angle (360°). CAS can be supplied with different mounting brackets to suit various installations on electric cranes.

Benefits: prevents accidents caused by load displacement when lifting off the ground, reduces the risk of rope guide wear and breakage and of rope failure, and extends the service life of the rope, rope guide and gearbox.

Key Features

SCM® Functions

All functions can be controlled remotely via the iOS and Android apps when used with the CLB control unit
Angle limitation with alarm and pre-alarm thresholds
When the angle approaches the set value the 1st warning relay switches; at the set value the final relay prevents side-pull lifting
Individual configuration of the 2 relay outputs
Communication with frequency inverters via Modbus
Real-time logging of angle faults
Continuous one-way data transmission via MODBUS
Set-up via keypad or Android / iOS app
Alarm signal if the angle sensor connection is lost
3-key keypad
