1. Whole set crane

The Single Girder Overhead Crane is one of the most popular lifting solutions for workshops, warehouses, and manufacturing plants. With a simple structure, reliable performance, and cost-effective design, it is widely applied in material handling, assembly lines, and logistics. This crane is especially suitable for light to medium-duty lifting operations.

2. Main girder

The main girder is the core load-bearing component of the single girder overhead crane. It is designed to provide maximum strength with minimum self-weight, ensuring smooth lifting operations, reduced wheel load, and longer service life.

3. Electric Wirerope Hoist

The electric wire rope hoist is the key lifting mechanism of the single girder overhead crane. It provides the vertical lifting motion, as well as trolley traveling, ensuring efficient and safe material handling. With compact design, reliable performance, and smooth operation, it is widely applied in workshops, warehouses, and production lines.

4. End Carriages

The end carriage (also called end truck) is the traveling mechanism that supports the main girder of the single girder overhead crane and enables the crane to move along the runway beams. It is a critical component for ensuring smooth, stable, and precise traveling motion.

5. Crane wheel

Material
Made of high-strength forged or cast alloy steel (65Mn, 42CrMo, or customized).
Heat-treated for maximum hardness, toughness, and wear resistance.
Processing
CNC machining ensures high dimensional accuracy and smooth rolling.
Surface hardening (HB 300–380) to resist rail wear.
Design Options
Double-flanged wheels – prevent derailment, commonly used in overhead cranes.
Single-flanged or non-flanged wheels – available for special applications.
Assembly
Mounted on high-precision bearings for stable rotation.
Grease-lubricated bearing housing with easy maintenance.

6. Crane hook

The hook is the direct lifting component of the single girder overhead crane, responsible for securely attaching and lifting loads. Designed with high-strength materials and strict safety standards, the hook ensures safe, stable, and efficient material handling for light to medium-duty applications.

7. Motor

The motor is the power source of the single girder overhead crane, driving the lifting, trolley traveling, and crane traveling mechanisms. With high efficiency, low noise, and strong overload capacity, the motor ensures reliable and safe operation for continuous material handling tasks.

8. Sound and light alarm system and limit switch safety device

Sound & Light Alarm System
Overview
The sound and light alarm system is an essential safety device designed to provide early warnings during crane operations. It enhances workplace safety by alerting nearby personnel of crane movement, lifting operations, or potential hazards.
Limit Switch Safety Device
Overview
The limit switch is a crucial safety component installed on lifting and traveling mechanisms. It prevents the crane hook, trolley, or end carriage from exceeding their designed travel limits, ensuring safe operation and protecting equipment from damage.

9. Safety Device

Overload Limiter
Prevents the crane from lifting beyond rated capacity.
Automatic cut-off with audible/visual alarm when overload is detected.
Limit Switches
Lifting Limit Switch: Prevents hook from over-hoisting or over-lowering.
Travel Limit Switch: Prevents trolley or crane end carriage from colliding with stops.
Emergency Stop System
Operators can instantly stop all crane movements in hazardous situations.
Improves reaction time in case of accidents.
Sound & Light Alarm System
Combines siren alarm and flashing lights.
Alerts nearby workers when the crane is in operation.
Buffer & Anti-Collision Device
Polyurethane buffers absorb impact when crane reaches end stops.
Optional infrared/radar anti-collision system for multi-crane operation on the same runway.
Motor Protection
Thermal overload protection prevents motor damage from overheating.
IP54/IP55 protection for dust and water resistance.

10. Control Mode

Pendant Control
Description: A wired push-button pendant is suspended from the crane or trolley.
Features:
Simple and economical control solution.
Direct and reliable operation.
Suitable for short spans and light-duty lifting.
Safety: Operator must walk with the load, ensuring close monitoring.
Remote Control (Wireless)
Description: Operated via a handheld wireless remote transmitter.
Features:
Freedom of movement for the operator.
Increases safety by keeping the operator away from the load.
Multi-function buttons with speed control available.
Safety: Avoids operator fatigue and reduces risk in hazardous areas.
Cabin Control (Optional)
Description: An enclosed cabin mounted on the crane girder.
Features:
Operator sits inside with joystick or console controls.
Suitable for heavier loads, long spans, or continuous duty cranes.
Provides better visibility and comfort for the operator.
Safety: Operator is isolated from ground-level hazards.
Advanced Options
Dual Control System: Combination of pendant + remote control for redundancy.
Variable Frequency Drive (VFD): Smooth acceleration, precise speed regulation, energy saving.
Intelligent Control: Optional integration with automation systems for semi-automatic or fully automatic operation.
