Draw Wire Sensor

Draw Wire Sensors are length measurement sensors that measure and generate the final working boom length from the crane center, to calculate the safe length of the lifted object along with the right angle

About Draw Wire Sensor

The Klug Avalon Mechatronics Pvt Ltd manufactures in-house Draw Wire Sensor/ Length cum Angle Sensor for the Cranes. At the time of long-distance suspended object lifting, the crane must be aware of the Exact boom length and the angle from the crane’s center to calculate the safe working condition and thus we offer a reliable draw-wire sensor

Note: At the time of primary installation, the draw-wire sensor is configured/set as per the load chart provided by the Machine manufacturer.

  • This length sensor available in various range
  • The single and dual-axis angle sensor
  • It is made as such that it withstand the harsh environment
  • Designed for heavy outdoor duty
  • One product covers two sensor application for length and angle
  • To measure Length-Angle:
  • Telescopic Boom Cranes,
  • Pick and carry cranes
  • Lorry Loader Crane
  • To measure fork height:
  • Forklift: Used. Models available are 3M & 5M
  • To Measure Length-Angle: Models available are 10m, 20m, 36m, 48m, 60m.
  • Forklift: Used to measure fork height. Models available are 3M & 5M.

The length sensor is so accurate that measures the safe working condition for the Machine Operator, However, when the lifted object capacity is overloaded as per the boom then the SLI system automatically lock the Crane/machinery until the operator press the bypass button provided in the SLI system control unit or until the Operator back to safe mode by adjusting the situation (angle/ boom length/ load)

Following are the conditions when the cut-off situation activates the system and lock the machinery is:

  • Radius / Low boom angle
  • Weight Overload situation
  • A 2 B Limit Crossover signals
  • Min. radius / High boom angle



Comprehensive Operator’s Training – where operators can practice with the equipment they will use each day. Worldwide we provide on site and in house training facilities, educating them about the safety of the cranes.

Let's Create a Safe On-Site Environment Together

No matter you are a Crane Owner. A Crane Service Provider, or an Orignal Equipment Manufacturer(OEM), we have a solution for you all.
What is an SLI System?

Safe Load Indicator is a safety control unit mounted in the crane’s cabin to alert the operator if the lift is exceeding the safe operating range of the machinery

Is it Necessary to install SLI System in our Crane?

Yes, Its necessary and important to avoid any future accident while working with materials without knowing the actual load and rated crane capacity.

What if We Have Old Crane dose your SLI System Support our Crane operation?

Yes Off course, As per your Crane capacity chart we will make a custom SLI system that match your Crane and Its Operation

We have pre-installed SLI System, still its need to update?

Yes, sometime pre fitted safety System are inadequate to protect hence we recommend to talk our Crane safety system officer and know the best suited solution for your crane.

What is an Anti-two Block Switch?

Over-hoist Switch measures the distance between the lifting hook block & Head of the boom crane, which avoids the collision between them and alerts the operator by sending signals via the SLI.
