Material: Rolled steel (I-beam) or welded box girder for rigidity.

Design: Lightweight yet strong, optimized for suspension from overhead structures.

② Electric Hoist

Types:

Wire Rope Hoist (1–20 tons, for heavier loads).

Chain Hoist (0.5–10 tons, for lighter loads).

Key Parts:

Lifting Motor – Powers the hoist.

Gearbox – Reduces speed and increases torque.

Brake System – Electromagnetic or mechanical for safety.

Drum & Wire Rope/Chain – Lifts and lowers the load.

Hook Block – Attaches to the load.

③ Trolley (Traveling Mechanism)

Function: Moves the hoist along the girder (cross travel).

Components:

Trolley Frame – Supports the hoist.

Wheels & Drive Motor – Allows movement along the girder.

Guides & Buffers – Prevents derailment and absorbs shocks.

④ End Trucks (End Carriages)

Function: Allows the crane to move along the runway beams (long travel).

Components:

Wheels – Run on suspended runway tracks.

Drive Motors – Powers longitudinal movement.

Buffers – Prevents collision at travel limits.

⑤ Suspended Runway System

Function: Supports the crane from the ceiling.

Emergency Stop Button – Immediate shutdown.

Anti-Collision System (For multiple cranes).

3. Optional Accessories

Magnetic Lifter – For handling steel plates.

C-Hook or Grabber – For specialized loads.

Easy Installation & Relocation

Can be mounted on existing roof structures without major modifications.

Modular design allows for quick assembly and disassembly.

Lightweight Yet Durable

Made from high-strength steel, offering good load capacity (typically 0.5–20 tons).

Suitable for light to medium-duty applications.

Smooth & Precise Operation

Electric hoist provides controlled lifting and lowering.

Optional Variable Frequency Drive (VFD) ensures jerk-free movement.

Low Maintenance

Fewer moving parts compared to hydraulic systems.

Sealed motors and enclosed tracks reduce wear and tear.

Flexibility in Application

Can be customized with different hoist types (chain or wire rope).

Adaptable for various lifting attachments (magnets, grabs, etc.).

Safety Features

Equipped with limit switches, overload protection, and emergency stop.

Anti-sway technology available for precise load positioning.

1. Warehousing & Logistics

Loading/unloading pallets, boxes, and packaged goods.

Moving heavy inventory in distribution centers.

2. Manufacturing & Assembly Lines

Handling raw materials, machinery parts, and finished products.

Used in automotive, electronics, and consumer goods industries.

3. Workshops & Repair Shops

Lifting engines, transmissions, and heavy equipment in auto garages.

Metal fabrication and welding shops for material handling.

4. Light Industrial Use

Textile factories (moving fabric rolls).

Packaging plants (positioning heavy bundles).

5. Retail & Commercial Spaces

Installing HVAC systems, lighting rigs, or stage equipment.

Used in large retail stores for stock management.

6. Food & Beverage Industry

Lifting bags of raw materials (sugar, flour, etc.).

Hygienic designs available for clean environments.

1. Design and Engineering
Initial Consultation: The process begins with discussions between the manufacturer and the customer to understand the crane's operational requirements, such as load capacity, span, lifting height, and environment (e.g., indoor or outdoor use, temperature conditions, etc.).

Engineering & Customization: The design team customizes the crane, including the structure, lifting system, and radio remote control features. Detailed engineering drawings and specifications are prepared, ensuring the crane meets all required standards and safety codes.

Control System Design: The radio remote control system is integrated into the design, with attention to ease of use, range, safety features (emergency stop, overload protection), and compatibility with the crane's other systems.

2. Material Selection and Procurement
Structural Materials: High-quality materials like steel are sourced for the crane's main beam, girder, end carriages, and other structural components. These materials are selected for their strength, durability, and ability to withstand heavy loads.

Mechanical Components: The components for the hoisting system, trolley, crane wheel, motors, gearboxes, and radio remote control system are procured from reliable suppliers.

Electrical Components: Wiring, electrical panels, switches, safety devices, and other electrical components for the crane's control system are also sourced.

3. Fabrication and Manufacturing
Main Beam Construction: The steel is cut, welded, and assembled to form the main girder (single beam) of the crane. This process often involves precision cutting, bending, and welding to meet specific design tolerances.

End Carriage Fabrication: The end carriages, which support the crane's travel mechanism, are fabricated and assembled. These components are designed for stability and strength, ensuring smooth crane movement along the tracks.

Assembly of Lifting Mechanism: The hoist, hook, and lifting mechanism are assembled, with motors, gears, and pulleys integrated into the system. The lifting system is tested for load-bearing capacity and smooth operation.

Trolley and Crane Traveling Mechanisms: The trolley and crane traveling mechanisms are built and assembled. This includes the wheels, motor, and rail system, ensuring smooth movement of the crane along the rails.

Radio Remote Control Installation: The radio remote control system is installed. This includes fitting the necessary receivers, antennas, and integrating the control system with the crane's electrical and mechanical systems.

4. Electrical and Control System Integration
Wiring and Electrical Systems: The electrical wiring is installed, connecting the hoisting system, control panel, motors, and radio remote control system. The wiring is tested for safety and compliance with electrical codes.

Control Panel Assembly: The crane's control panel is assembled and integrated with the radio remote control system. It is tested for responsiveness and safety features, including emergency stop and overload protection.

Safety Features: Safety devices such as limit switches, overload sensors, and sound and light alarms are installed and integrated into the control system. These systems ensure safe crane operation and prevent damage.

5. Testing and Quality Control
Load Testing: The crane is subjected to a load test to ensure it can handle the specified weight capacity. The test is done using calibrated weights to verify the crane's performance under operational conditions.

Operational Testing: The crane undergoes a full operational test, where it is run through its motions (lifting, lowering, traveling, etc.) using the radio remote control. The crane's response to commands, including emergency stop and safety alarms, is closely monitored.

Electrical & Mechanical Testing: All electrical systems, including the radio remote control, are tested for functionality and safety. The motors, brakes, and electrical wiring are inspected for proper operation.

Inspection for Compliance: The crane is inspected for compliance with local and international standards (such as ISO, CE, or OSHA) to ensure it meets safety regulations. The structure, load-bearing components, and safety systems are thoroughly checked.

6. Final Assembly
Final Assembly and Inspection: After testing, the crane is fully assembled, with all components securely attached and double-checked for accuracy. The radio remote control is configured, and the system is tested one last time to ensure seamless integration.

Painting & Finishing: The crane is painted with protective coatings to prevent corrosion and improve its appearance. The final finishing touches are added to the structure, including any labeling or safety markings.

Documentation: All necessary documentation, including manuals, certificates of compliance, test reports, and warranty information, are prepared for the customer.
