Overhead and Gantry Cranes Custom Solution for South Africa Client

Customer Procurement Requirements

• Product Combination Requirements: The client needed to simultaneously purchase double girder overhead cranes, single girder semi-gantry cranes, and single girder overhead cranes to meet material handling requirements across different workshop scenarios, including assembly areas, storage bays, and maintenance zones.
• Localized Configuration Requirements: All equipment must be adapted to South Africa’s 380V / 50Hz / 3-phase voltage standard, and components must be suitable for Durban’s coastal humidity and ambient conditions.
• Technical Support Requirements: Complete installation drawings, wiring diagrams, and technical documentation were required to support the client’s in-house team in carrying out installation and commissioning independently.
• Delivery Timeline: Strict delivery schedule required to align with the facility’s production line commissioning timeline.

Customized Solution

1. Multi-Type Crane Solution for Workshop Material Handling

(1) Semi-Gantry Cranes — For Wall-Side Operations, Compact Design for Limited Space

For wall-side workstations with limited workshop space and conditions where floor rails could not be installed, semi-gantry cranes were selected with a focus on space efficiency and operational safety:

• Equipped with vertical motors featuring compact structure and high transmission efficiency, reducing leg footprint for maximum usable floor space.
• Polyurethane-coated steel wheels eliminate the need for floor rails, reducing floor wear, improving stability, and minimizing noise. Guide wheels installed on end beams prevent wheel deviation and ensure safe operation.
• Steel protective frame installed around the ground beam motor to guard against accidental impact in complex workshop environments, improving durability and site safety.

(2) Double Girder Overhead Cranes — High Capacity, Smooth Operation & Low Energy Consumption

To meet the client’s need for two cranes operating in the same span with higher stability and user experience requirements, Suncan Crane customized high-specification double girder overhead cranes with enhanced safety, performance, and energy efficiency:

• Equipped with infrared anti-collision system. When approaching the safety threshold, the system automatically slows down or brakes to prevent collision between cranes operating on the same runway.
• Variable frequency control for both hoisting and traveling ensures smooth, impact-free operation with significantly higher positioning and control accuracy compared to standard overhead cranes.
• Operating noise maintained below 70 dB, creating a quieter workshop environment. Overall energy savings of up to 30%, reducing long-term electricity costs for the facility.
• Modular design for easier maintenance, lowering lifecycle maintenance costs and effectively extending service life.

(3) Single Girder Overhead Cranes — Cost-Effective Standard Solution

For applications requiring only basic lifting functionality with stable operation, and where three cranes needed to operate simultaneously on the same runway, a standardized configuration with optimized travel mechanisms was adopted:

• Standard single girder overhead crane with reliable structure and strong versatility, reducing procurement cost while fully meeting operational requirements.
• Both crane travel and trolley travel mechanisms equipped with variable frequency drives, effectively reducing start-stop impact and ensuring smooth operation.
• Infrared anti-collision system installed to eliminate collision risks during simultaneous operation of three cranes on the same runway, ensuring operational safety at all times.

2. Adaptation to Durban, South Africa Operating Conditions

• Power system adaptation: All equipment designed for 380V / 50Hz / 3Ph South African standard voltage to ensure full compatibility with the local power grid in Durban.
• Coastal environment protection: Anti-corrosion coating applied to all structural steel components to withstand Durban’s coastal humidity and saline atmosphere, ensuring long-term durability.
• Bilingual labeling: Nameplates and specification instructions for all mechanical and electrical components provided in both Chinese and English, facilitating local operation and maintenance by the Durban-based team.

3. Full Documentation for Client Self-Installation

• Complete technical document delivery: Full set of drawings provided, including general arrangement drawings (CAD format), main end beam assembly drawings, joint section drawings, electric hoist general drawings, and electrical wiring diagrams.
• Original factory documentation: Equipment supplied with inspection reports, material certificates, packing lists, and component manuals in electronic format for easy reference.
• Remote technical support: Continuous remote guidance provided throughout the installation process, with prompt assistance for any technical issues encountered by the client’s team in Durban.

Project Outcome: Client Satisfaction & Long-Term Partnership

• All cranes run smoothly with accurate positioning, effectively meeting the entire workshop’s lifting and material handling requirements.
• Production of all units was completed within the agreed 50-day manufacturing window, followed by safe sea freight delivery to Durban port within approximately 1 month. The client completed installation and commissioning within 2 weeks, enabling the production line to be put into operation on schedule.
• Client Mr. Zekeriyaaa Kara expressed high satisfaction with product quality, manufacturing capability, and service. Discussions for follow-up cooperation and additional equipment orders have already been initiated.
