1. Main Girder

The main girder is the primary load-bearing structure of the crane. It is usually manufactured from high-quality steel plates with a welded box-type or I-beam design to provide excellent strength, rigidity, and durability.

2. Electric Wire Rope Hoist

The electric wire rope hoist performs the lifting and lowering operations. It includes the lifting motor, gearbox, drum, wire rope, hook block, and braking system, ensuring smooth and reliable material handling.

3. End Carriages

End carriages are installed at both ends of the main girder and support the crane's movement along the runway. They are equipped with wheels, motors, reducers, and buffers for stable travel.

4. Crane Traveling Mechanism

The traveling mechanism consists of motors, gear reducers, wheels, and drive systems that enable the crane to move horizontally along the workshop rails with precision and stability.

5. Wireless Remote Control System

The remote control system allows operators to control lifting, lowering, cross travel, and long travel functions from a safe distance. It improves operational flexibility, safety, and efficiency.

6. Electrical Control Panel

The electrical control panel contains contactors, inverters, circuit breakers, relays, overload protection devices, and other electrical components responsible for controlling and protecting crane operations.

7. Power Supply System

The crane receives electrical power through conductor rails or festoon cable systems, ensuring continuous and reliable energy transmission during operation.

8. Hook Block Assembly

The hook block includes the crane hook, pulley system, safety latch, and bearings. It is designed to securely lift and transport heavy loads while preventing accidental disengagement.

9. Safety Protection Devices

Multiple safety devices are integrated into the crane, including:

Overload limiter

Lifting height limit switch

Traveling limit switches

Emergency stop button

Phase sequence and phase loss protection

Motor overload protection

Buffers and anti-collision devices

.

10. Variable Frequency Drive (Optional)

Variable Frequency Drives (VFDs) can be installed to provide smooth acceleration, deceleration, precise positioning, reduced mechanical wear, and energy savings.

These components work together to ensure that the 20T single girder overhead crane with remote control operates safely, efficiently, and reliably in various industrial applications.
