Container Straddle Carrier – 35-Ton Heavy-Duty Handling Equipment for Port Logistics

Overview

This case analysis introduces the GKYS3532B container straddle carrier, designed to address the core need for efficient container flow in modern ports and logistics hubs.

Featuring an innovative portal frame design, it integrates horizontal transport, stacking, and loading/unloading functions, effectively solving industry pain points including single-function equipment, multiple handling links, and low yard utilization in traditional terminal operations.

Basic Parameters

Parameter Item	Technical Specification
Structure Type	Dual-lane independent structure
Rated Load	135 tons (single lane)
Container Types Processed	20-foot standard containers (customizable)
Flipping Angle	Adjustable from 0 to 180 degrees
Lifting Height	800 mm
Lateral Movement	2900 mm
Motor Power	15 kW-18.5 kW
Power Supply Specifications	380V/50Hz
Total Weight	115.4 tons

How It Works

The equipment maneuvers over container rows using its portal frame and engages containers with an automatic spreader.

A hydraulic system enables two-stage lifting (1500mm) for 1-2 high container stacking.

Powered by a closed travel system and supported by four solid tires, it moves flexibly at 3-5km/h, enabling rapid transfer of containers between the yard and quay cranes.

The Challenges

Operational Efficiency Bottleneck: Single-lane design leads to slower container processing speeds, which cannot meet the throughput demands of modern ports.
Low Space Utilization: Traditional equipment occupies large areas but has limited efficiency per unit area.
Safety Challenges: High demands for stability and control precision during heavy-load flipping processes.
Inadequate Adaptability: Fixed designs struggle to meet the diverse container processing needs.
High Maintenance Costs: Equipment reliability and ease of maintenance are crucial in high-intensity operating environments.
