KGD SERIES · DOUBLE GIRDER GANTRY CRANE
KGD双梁门式起重机
Robust Gantry Lifting for Higher Capacities, Longer Spans and Demanding Operations
The KGD double girder gantry crane provides a robust structural platform for higher-capacity lifting, longer spans, demanding operating cycles and application-specific material handling.
Its self-supporting gantry structure can be configured for indoor workshops, covered production areas, outdoor yards and industrial sites.
The bridge, trolley, hoisting system, gantry legs, travel drives and controls are engineered around the load, working area, site conditions and required operating duty.

ENGINEERING DECISION
When the Lifting Requirement Demands a More Robust Gantry System
A double girder gantry crane may be considered when the project requires higher capacity, longer span, demanding operating duty, improved lifting-height utilization or application-specific hoisting equipment.
The correct configuration depends on the load characteristics, required working area, operating frequency, runway and foundation conditions, lifting attachments and site environment.
HIGHER-CAPACITY CONFIGURATION
Twin bridge girders provide a robust structural platform for the trolley and project-specific hoisting system.
LONGER SPAN AND COVERAGE
Span, travel length and optional cantilevers are coordinated with production, storage, assembly and loading areas.
DEMANDING OPERATING DUTY
Operating frequency, daily working hours and production rhythm are reviewed when selecting the duty classification and drives.
SPECIALIZED LIFTING
Main and auxiliary hoists or application-specific lifting attachments can be reviewed according to the load and project scope.
KGD SYSTEM CONFIGURATION
A Double Girder Gantry System Engineered as One Complete Crane
The twin bridge girders, top-running trolley, hoisting mechanisms, supporting legs, end carriages, travel drives and electrical controls are engineered as one coordinated gantry crane system.
The final structure is determined from the load, span, lifting height, travel length, cantilever arrangement, operating duty, runway conditions and installation environment.
- Twin bridge girders and top-running trolley
- Main hoisting mechanism
- Auxiliary hoist where required
- Supporting legs, end carriages and travel drives
- Ground runway, power supply and controls
- Optional cantilever and environment-specific protection
INDOOR, COVERED OR OUTDOOR CONFIGURATION
Indoor projects are coordinated with building clearances, floor layout and power supply. For covered or outdoor projects, electrical protection, coating, wind, rain exposure, drainage and parking requirements are reviewed according to the site.

CRANE CONFIGURATION SELECTION
Is a KGD Double Girder Gantry Crane Necessary for Your Project?
KGD MAY BE SUITABLE WHEN:
- Higher capacity or a longer span is required
- The crane will operate at a demanding duty
- A top-running trolley provides the required arrangement
- Main and auxiliary hoists are required
- Special lifting attachments or process integration are needed
- A self-supporting gantry structure suits the site layout
CONSIDER ANOTHER CONFIGURATION WHEN:
- The verified KGS range meets the lifting requirement
- A lighter and more compact gantry structure is preferred
- A semi-gantry crane better suits the available support
- A building-supported overhead crane provides a better indoor layout
- The site cannot support the required runway or foundation
