Safety first in crane operation. A slight calculation error in lifting capacity can result in costly equipment damage or, at worst, life-altering accidents. That's where the Safe Load Indicator (SLI) comes in - your crane's onboard safety supervisor.
A Safe Load Indicator (SLI) is an electronic or mechanical device installed on cranes to avoid overloading. It continuously checks the weight lifted and compares it with the safe working limit of the crane.
Whenever the load is above the allowed capacity, the SLI instantly:

The SLI generally consists of:
These components send real-time data to the control panel, which calculates if the load exceeds the pre-set safety threshold.
| Type | Ideal For | Features |
|---|---|---|
| Basic Analog SLI | Small construction cranes | Mechanical dial, minimal alerts |
| Digital SLI | Tower Cranes, Mobile Cranes | LCD display, overload alarms |
| Advanced ACD-SLI Combo | Complex job sites | GPS-based anti-collision + SLI, remote monitoring |

A Safe Load Indicator is not a tool - it's a guarantee of control, safety, and responsibility on location.
Don't wait for a safety matter to arise.
A Safe Load Indicator ensures crane operators' safety by continuously monitoring the weight lifted. If it's too heavy, it alerts or shuts down the crane to avoid accidents.
Yes, more often than not you do. Indian safety codes suggest or stipulate Safe Load Indicators for cranes in order to prevent overloading and safe lifting work.
Crane types such as tower cranes, mobile cranes, derrick cranes, and passenger hoists themselves should all use Safe Load Indicators to observe weight and prevent unsafe loads.
Yes, you can. If you're engaged in a short-term project, hiring a Safe Load Indicator is a wise, cost-effective move. Several crane safety providers in India provide rental options.
A Safe Load Indicator verifies the load weight, and an Anti-Collision Device makes cranes collide with other cranes. A few high-technology systems do both.
