SZ-E02 Excavator load indicator
Product Overview
The SeeZol Excavator Load Indicator, also known as Load Moment Indicator (LMI) or Safe Load Indicator (SLI), is a real-time safety solution for excavators used for lifting, demolition, and material-handling duties. Through a human-machine interface and various sensors, it reflects boom height, angle, lifting weight, and overload status directly on the monitor, allowing the operator to keep the machine within a safe operating range at all times.
When the excavator approaches or exceeds the allowable safety threshold, the system triggers instant audible and visual alarms—minimizing accidents, equipment damage, and structural failures. Its rugged design ensures durability in harsh environments, and broad compatibility across major equipment brands makes it a versatile addition to any construction or industrial fleet.
