Electric Container Straddle Carrier – Zero-Emission Solution for Green Ports

Overview

This case analysis introduces the electric container straddle carrier, designed to meet the dual demands of environmental protection and operational efficiency in modern ports and logistics hubs.

Through its innovative electric drive system and portal frame design, the equipment achieves zero emissions, low noise, and high efficiency in container handling operations, providing an ideal solution for green port development.

Basic Parameters

Parameter	35T Model	60T Model	80T Model
Rated Capacity	35 tons	60 tons	80 tons
Inner Frame Width	3200mm	3700mm	3700mm
Lifting Height	1550mm	1700mm	1700mm
Travel Speed	5-7km/h	3-5km/h	3-5km/h
Motor Power	80KW	90KW	120KW
Turning Radius	7000mm	10000mm	12000mm

How It Works

The equipment utilizes a permanent magnet synchronous motor drive system with large-capacity lithium iron phosphate battery packs.

Professional hydraulically controlled spreaders enable precise container handling, while rubber-tired chassis provide flexible mobility.

An intelligent control system coordinates lifting, traveling, and steering functions to accomplish rapid container transfer within the yard.

The Challenges

Environmental Pressure: High emissions from traditional diesel equipment fail to meet green port requirements
Operating Costs: Continuously rising fuel costs impact profitability
Noise Pollution: Loud operation affects working environment and surrounding communities
