Engineered for the safety of construction machinery lifting operations, the Hirschmann LMI Load Moment Indicator serves as the core safety component for mobile cranes, all-terrain cranes, and similar equipment.

The Hirschmann HC4900 Load Moment Indicator is a core safety protection device designed for all types of construction cranes. It collects critical operational data such as load weight, boom length, and angle in real time, dynamically calculates the lifting moment, and compares it with preset safety thresholds. If an overload or over-limit risk is detected, it immediately triggers an audible and visual alarm and outputs control signals, effectively preventing serious accidents and protecting personnel and equipment safety.

The EPEC 2023/2024 is an embedded control unit designed exclusively for construction machinery, serving as the “electronic control brain” in harsh-environment equipment such as excavators, cranes, and mining machinery. It features a rugged cast-aluminum heat-dissipating housing, supports CAN bus communication and CODESYS programming, and reliably drives hydraulic systems, engines, and various sensors.
