1.Main beam

1)Structure
Double main beams: Two parallel box-type or I-beam girders.

Box girder design (most common in Euro cranes):

Welded, rectangular box structure for high torsional stiffness and strength.

Provides better performance for long spans and heavy-duty loads.

Supports the trolley which travels between the girders, carrying the hoist and hook.

2)Material
High-strength structural steel, typically:

Q345B/Q355B (Chinese standard)

S355JR or S235JR (European EN10025 standard)

All welds are carried out to ISO or EN welding standards, with quality testing like UT or RT if needed.

 

2.Lifting System

Key Components
a) Motor
Three-phase asynchronous motor

Typically pole-changing or variable frequency drive (VFD) controlled

Smooth start/stop for precise positioning and reduced swing

Brand examples: SEW, ABM, Siemens

b) Wire Rope Drum
Grooved drum made of steel, ensures correct rope layering

Optimized to reduce wear and extend rope life

c) Wire Rope
High-strength galvanized steel wire rope

Safety factor: typically ≥5–7 times rated capacity

d) Hook Block
Forged hook, swivel type, equipped with a safety latch

Rotates 360° manually or optionally with motorized rotation

Hook block includes pulley system for mechanical advantage

e) Trolley
Carries the hoist along the top of the girders

Equipped with travel motors and wheels with soft start and VFD

Side rollers prevent derailment
 

3.End carriage

Structure & Configuration
Two end carriages, one on each side of the crane, connected to the double girders via high-strength bolts or welded joints.

Fabricated from steel box or rectangular tube sections, precision-machined.

Designed with camber for optimal load distribution and smooth travel.

 

 

4.Crane travelling mechanism

The crane traveling system of a Euro double girder overhead crane with hook enables the entire bridge (main beam + end carriages) to move longitudinally along the runway rails, covering the full working area. In European-style cranes (FEM/DIN standard), this system is engineered for precision, smooth operation, low maintenance, and energy efficiency.

5.Trolley travelling mechanism

The trolley traveling system of a Euro double girder overhead crane with hook is the mechanism that allows the hoist and hook to move laterally (side to side) along the main girders. This system is key to precise load positioning and efficient material handling.

In a Euro-style design, the trolley traveling system emphasizes compact size, smooth and precise movement, low noise, and modularity, complying with FEM/DIN standards.

6.Crane wheel

The crane wheels of a Euro double girder overhead crane with hook are essential components that allow the bridge (main girders + end carriages) to travel along the runway rails. These wheels bear the entire crane's deadweight plus the lifted load, so they are designed for high strength, durability, and smooth rolling-in compliance with European FEM/DIN standards.

7.Crane Hook

The crane hook of a Euro double girder overhead crane with hook is the final load-handling device, used to secure and lift loads via slings, chains, or other rigging equipment. In Euro-style cranes (designed per FEM/DIN standards), the hook is engineered for safety, durability, precise lifting, and compliance with international norms.

8.Motor

The motor of a Euro double girder overhead crane with hook is a core component driving various crane motions-lifting, trolley traveling, and bridge traveling. Euro-style cranes, designed to FEM/DIN standards, use energy-efficient, compact, and VFD-compatible motors that ensure smooth, precise, and reliable operations.

9.Sound and light alarm system & limit switch

1)Sound and Light Alarm System
Purpose:
To warn nearby personnel of crane movement or operational status, improving workplace safety.

Commonly activated when the crane or trolley is traveling or when lifting/lowering occurs.
2)Limit Switches
Purpose:
To physically detect and stop the crane or trolley when they reach the end of travel limits, preventing mechanical overrun and potential damage or accidents.

Also used to limit hoist hook lifting and lowering limits.

10.Safety Devices

1. Overload Protection Device
Purpose: Prevents lifting loads exceeding crane's rated capacity, protecting structural components and hoist mechanisms.

2. Limit Switches
Bridge Travel Limit Switches: Stop crane travel at runway ends.

Trolley Travel Limit Switches: Stop trolley at main girder ends.

Hoist Upper/Lower Limit Switches: Prevent over-hoisting and excessive lowering to avoid rope slack or hook collision.

3. Emergency Stop (E-Stop) Buttons
Located on all operator control stations (pendants, cabins, remote controls).

Instantly cuts power to crane drives when pressed.

Overrides all other commands, ensuring immediate halt of all crane movements.

4. Anti-Collision Devices
Purpose: Prevent collisions with adjacent cranes or obstacles.

5. Travel and Hoist Brakes
Fail-safe electromagnetic disc brakes engage automatically when power is lost or emergency stop is activated.

Ensure safe holding of the load when stationary.

11.Control Mode

1. Pendant Control (Wired Control)
Description: A handheld control box connected by a cable to the crane.

2. Radio Remote Control (Wireless Control)
Description: Wireless handheld transmitter allows the operator to control crane motions remotely.

3. Cabin Control
Description: Operator sits inside a cabin mounted on the crane bridge.

4. Automated / Semi-Automated Control
Description: Using PLC/automation systems for pre-programmed or assisted crane motions.
