Project Background
In October 2023, a private port and cargo handling operator in the Casablanca region of Morocco approached Haitai Crane with a clearly defined requirement: a 90-Ton Rubber Tyred Gantry Crane capable of handling oversized steel products, heavy industrial equipment, and other large cargo in an open storage yard. The crane also needed to be delivered within a strict 14-week project schedule.
Casablanca is one of Morocco’s major commercial and industrial port centers on the Atlantic coast. Its port facilities handle containers, general cargo, steel products, heavy packages, and industrial equipment, creating demand for flexible heavy-lifting solutions in port and industrial yards.
For this project, the customer required a mobile gantry crane that could provide high lifting capacity without depending on permanent rails. After evaluating the technical requirements and operating conditions, the customer selected Haitai Crane’s YTL90t-8m heavy-duty rubber tyred gantry crane.
The project focused on four key priorities: high lifting capacity, flexible yard operation, reliable performance in a coastal environment, and complete technical and export documentation.
Client Requirements
The Moroccan customer required a heavy-duty rubber tyred gantry crane for demanding cargo-handling operations. The main requirements included:
- 90-ton rated lifting capacity for heavy steel products and industrial equipment
- 8-meter crane span suitable for the planned open-yard operating area
- Rubber-tyred travel system for flexible movement without fixed rails
- Variable frequency drive (VFD) for controlled crane movement
- Reliable operation in a coastal environment with exposure to humidity and salt-laden air
- CE marking and the required Declaration of Conformity and technical documentation
- Complete operation, maintenance, and commissioning documentation
- Documentation suitable for Moroccan import and customs procedures
- Delivery within 14 weeks to meet the customer’s project schedule
The customer also required the crane to be suitable for local operator training and straightforward daily maintenance after commissioning.
Solution: YTL90t-8m 90-Ton Rubber Tyred Gantry Crane
Based on the customer’s lifting requirements and yard conditions, Haitai’s engineering team recommended the YTL90t-8m 90-ton rubber tyred gantry crane.
Unlike rail-mounted gantry cranes, the rubber tyred design allows the crane to travel across prepared yard surfaces without permanent rails. This provides greater flexibility when the cargo-handling layout needs to accommodate different storage areas, heavy cargo lanes, or future operational changes.
The YTL90t-8m was configured as a heavy-duty mobile gantry crane for industrial and port-related cargo handling rather than being limited to standard container-yard applications.
| Parameter | Specification |
|---|---|
| Product | HT Crane Double Girder RTG Crane |
| Rated Lifting Capacity | 90 Tons |
| Span | 8,000 mm |
| Drive System | Variable Frequency Drive (VFD) |
| Wheel Configuration | 8-wheel bogies, self-steering rubber tyres |
| Operating Temperature | –10°C to +50°C |
| Application | Heavy cargo and industrial material handling |
| Compliance Documentation | CE Declaration of Conformity and project technical documentation |
The 8-meter span was selected to match the customer’s planned cargo-handling lanes and operating area. The rubber-tyred travel system also reduced the need for fixed rail infrastructure, giving the operator more flexibility when moving the crane between designated working areas.
Morocco-Specific Adaptations
To suit the Moroccan operating environment, Haitai’s engineering team reviewed the standard crane configuration and made several project-specific adjustments.
Coastal Corrosion Protection
Because the project was located in the Casablanca port environment, corrosion protection was an important consideration. A multi-layer protective coating system was applied to the crane structure to improve resistance against humidity and salt-laden coastal air.
The surface treatment and coating system were selected according to the project requirements and the intended operating environment.
Heavy-Duty Electrical and Drive System
The crane was equipped with a variable frequency drive system to provide smoother acceleration, deceleration, and travelling control. This helps reduce mechanical shock during repeated lifting and travelling operations.
Electrical components and control equipment were selected according to the project’s technical specifications and applicable safety requirements.
Operator-Friendly Control System
The control system was configured to provide clear operating functions and alarm indications. The customer also received detailed operation and maintenance documentation to support operator training and routine maintenance after installation.
Where required, project documentation could be provided in English and French to facilitate communication with the Moroccan project team and local personnel.
Factory Acceptance Test and Quality Inspection
Before shipment, the 90-ton rubber tyred gantry crane underwent factory inspection and load testing according to the agreed project test procedure.
For the project, the crane was tested at 125% of its rated lifting capacity, equivalent to 112.5 metric tons, as specified by the applicable project testing requirements.
The inspection covered the main structural and operating functions, including:
- Main structure and welding quality
- Hoisting mechanism
- Trolley and travelling systems
- Brake performance
- Electrical control system
- Safety protection devices
- Emergency stop functions
- Load testing
- Crane travelling and steering functions
The customer or designated inspection representative could review the relevant test documentation before shipment.
This factory acceptance process helped verify the crane’s operating performance before it was dispatched to Morocco.
Export & Delivery Process
Haitai Crane managed the export preparation from factory inspection through shipment and site commissioning.
Technical Documentation
The export documentation package included the applicable technical documentation, such as:
- CE Declaration of Conformity
- Operation and maintenance manual
- Electrical documentation
- Load test documentation
- Equipment drawings
- Spare parts information
- Installation and commissioning instructions
- Packing list and commercial export documents
For Moroccan import procedures, the final customs classification and documentation were prepared according to the actual equipment configuration and applicable customs requirements rather than relying on a generic HS-code assumption.
Morocco’s import control framework requires supporting documentation for industrial products subject to applicable technical regulations, and import procedures can involve documentary inspection and conformity assessment depending on the product category.
Sea Freight to Morocco
The crane was prepared for international transportation as heavy project cargo. Structural components were carefully marked and packed to simplify unloading and on-site assembly.
Machined surfaces and exposed components were protected against moisture and corrosion during transportation. Structural members were assigned clear identification numbers so that the installation team could efficiently match each component with the assembly drawings.
The equipment was then shipped by sea to Morocco for delivery to the customer’s project site in the Casablanca area.
On-Site Installation and Commissioning
After the equipment arrived in Morocco and the site was ready for installation, Haitai dispatched an engineering team to support erection and commissioning.
The installation process included:
- Unpacking and component inspection
- Main structure assembly
- Installation of hoisting and travelling systems
- Electrical connection and control-system inspection
- Safety-device testing
- No-load testing
- Load testing
- Travelling and steering tests
- Final commissioning
- Operator training
The 90 ton RTG crane was fully erected and commissioned within approximately 8 working days under the agreed site conditions.
The commissioning team also provided practical operator training covering safe lifting procedures, crane travelling, load positioning, emergency operations, daily inspection, and basic maintenance.
This on-site support allowed the customer to begin operating the 90-ton rubber tyred gantry crane with a clear understanding of its operating procedures and maintenance requirements.

A 90-ton rubber tyred gantry crane can travel between designated working areas on rubber tyres, reducing dependence on permanent rail infrastructure.
This makes it particularly suitable for:
- Heavy steel product handling
- Industrial equipment handling
- Oversized cargo yards
- Port general-cargo operations
- Shipyard and fabrication yards
- Construction material storage
- Heavy machinery manufacturing plants
- Logistics yards requiring flexible lifting operations
For projects where cargo types, storage locations, or yard layouts may change over time, the mobility of a rubber tyred gantry crane can provide an important operational advantage.
