Most main beams are constructed in an I-beam or box beam design to ensure maximum load distribution while keeping the structure lightweight.

The structure minimizes deflection and maximizes efficiency in load handling.

3)Welded Design:

The main beam is fabricated using advanced welding techniques such as submerged arc welding, ensuring precision, uniformity, and a strong bond.

Welded seams are inspected to meet strict safety and quality standards.

4)Customizable Span and Dimensions:

The length and width of the main beam can be customized to match the 2t mobile gantry crane's application, span, and load capacity.

Built-in limit switches stop the hoist at safe upper and lower positions, preventing over-travel of the hook.

5)Durability:

Components are made of high-strength materials designed to endure heavy-duty cycles in harsh environments.

3.End carriage

1)Frame:

Fabricated from high-strength steel, such as Q235B or Q345B, to ensure durability and rigidity.

Designed to withstand loads transferred from the main beam and maintain the 2t mobile gantry crane's balance during operation.

2)Wheel Assemblies:

Equipped with forged steel wheels or cast steel wheels, designed to handle high loads while minimizing wear.

Available in two configurations: rail-mounted wheels for fixed tracks or rubber wheels for portable, free-moving cranes.

Wheels may include flanges to prevent derailment during movement.

2)Double Flanged Wheels:

Flanges on both sides for added stability and to prevent derailment.

Suitable for applications requiring high safety and precision.

3)Flat Wheels:

No flange; used in systems with external rail guides or in rubber-tired gantry cranes.

4)Rubber-Coated Wheels:

Coated with polyurethane or rubber for noiseless and smooth movement on surfaces without steel rails.

Common in portable gantry cranes or special-purpose applications.

7.Crane Hook

Components of the Crane Hook

1)Hook Body:

The main structure of the hook, often made from forged alloy steel, provides the strength to lift heavy loads.

The shape is carefully designed to optimize strength and minimize the risk of fatigue.

2)Safety Latch:

A spring-loaded latch or locking pin that secures the load to the hook, preventing accidental disconnection during movement.

The latch mechanism is typically manual or automatic.

3)Hook Eye:

The top part of the hook, where the lifting chain, wire rope, or shackles are attached.

It is designed for optimal strength and durability.

4)Load Bearing Surface:

The part of the hook where the load is applied. This area is designed to ensure that the load is evenly distributed and does not cause localized stress.

5)Swivel Mechanism (Optional):

Some cranes are equipped with hooks that feature a swivel mechanism to allow the hook to rotate freely. This is particularly useful in applications where the load must be rotated during lifting or positioning.

Motor

Control and Protection Features

1)Variable Frequency Drive (VFD):

A VFD is used in many crane motors to control the speed and torque of the motor. This allows for smoother acceleration and deceleration, reducing mechanical wear on the crane and providing better load handling precision.

2)Overload Protection:

Motor protection systems are in place to prevent the motor from burning out under excessive load conditions. These protection features monitor the motor's current and temperature, triggering an automatic shutdown if needed.

3)Soft Start/Stop:

A soft starter gradually increases the voltage supplied to the motor, reducing mechanical stresses during startup and shutdown. This also helps avoid sudden jerks when starting or stopping the crane, especially under heavy loads.

4)Thermal Overload Protection:

Many motors are equipped with thermal sensors or built-in protection mechanisms that disconnect the motor if it exceeds a safe operating temperature. This prevents motor damage and ensures the crane operates within safe parameters.

Sound and light alarm system & limit switch

1)Sound and Light Alarm System

The sound and light alarm system serves as a critical safety feature in gantry cranes, alerting operators and workers nearby about crane movements or specific actions like lifting, lowering, and approaching load limits. This system enhances safety by providing audible and visible warnings of potential hazards or abnormal situations.

2)Limit Switches

A limit switch is a mechanical or electrical device used to restrict or limit the movement of the crane, preventing it from exceeding safe operational limits. These are critical safety features, ensuring that the crane does not run into physical obstructions or exceed its operational parameters.

10.Safety Devices

1. Overload Protection Device: Prevents the crane from lifting loads beyond its rated capacity.Prevents structural damage to the crane and accidents caused by overloading.

2. Limit Switches: Restrict the movement of various crane mechanisms to prevent over-travel or collision. Stops the crane from moving beyond its track limits. Prevents mechanical damage and ensures safe operation within predefined boundaries.
