Panduan Lengkap Daya Derek Gantry dan Overhead: Mengoptimalkan Desain Sirkuit Pabrik dan Pemilihan Peralatan

Tanggal: 27 Juni 2025

Daftar isi

When choosing overhead cranes and gantry cranes, power consumption is often one of the primary concerns for customers. This is because, during the initial design phase of a facility, customers need to understand the power requirements of all equipment to plan the facility’s electrical system accordingly. Overhead and gantry crane power consumption is a key factor in this process. Therefore, understanding the power requirements of cranes is crucial for equipment selection, facility design, and cost estimation.

How Overhead and Gantry Crane Power Data Assists Project Engineers:

Electrical Design: Power data helps estimate the power supply requirements of a workshop or site.
Equipment Compatibility: Ensures the crane’s power specifications are compatible with existing electrical systems.
Cost Optimization: Avoids power wastage while meeting operational needs, optimizing both initial and ongoing costs.

Below, we list the power specifications for various standard crane models.

Bridge Crane Power Consumption

The total power consumption of a crane is the sum of the power for the hoisting mechanism, trolley movement, and crane movement.
