Overhead Travelling Crane 150 Tons

 

 

An Overhead Travelling Crane (150 Tons) is a powerful and versatile lifting system designed to handle extremely heavy loads, commonly used in heavy-duty industrial settings. Here's a brief introduction to its main features:

 

 

Warranty:12 months

Weight (KG):500 kg

Feature:Bridge Crane

Condition:New

Power Source:3 Phase 380V 50hz or customized

 

 

Double Girders

Description: Two parallel beams (girders) that form the main structural component of the crane.

Function: The double girder design provides added strength and support for the heavy load. The trolley and hoist travel along these girders, allowing the crane to handle very heavy loads (up to 150 tons).

Trolley

Description: The trolley is a motorized unit that carries the hoist. It runs horizontally along the girders.

Function: It moves horizontally across the bridge to position the hoist over the load for precise lifting and transporting. The trolley is designed to handle heavy-duty operations and support the 150-ton capacity of the crane.

Hoist

Description: The hoist is the lifting mechanism, typically a wire rope hoist for high-capacity cranes.

Function: The hoist lifts and lowers the load using a drum and wire rope mechanism. It can lift loads up to 150 tons and is equipped with motors, brakes, and limit switches for precise control and safety.

 

 

Control System

Description: The control system operates the crane's movements and hoisting operations.

Types:

Pendant Control: A wired handheld control system.

Wireless Remote Control: Allows the operator to control the crane from a distance for better visibility and safety.

Cabin Control: For large cranes, an operator cabin may be mounted on the bridge to give the operator full visibility and control over crane operations.

Function: The control system enables precise control of all crane movements, including lifting, lowering, and horizontal travel of both the bridge and the trolley.

 

 

Crane:The function of the crane is to steer the entire crane forward and backward along the length of the workshop. An electric motor provides the power and the reducer is reduced to rotate the wheels, thus realizing the longitudinal movement of the crane.

 

 

Trolley:The primary function of the trolley is to move goods picked up on the tracks on the bridge left and right. The trolley is equipped with a movement punch and limit switch to ensure safe operation. The electric motor drives the motion mechanism of the trolley to rotate back and forth on the ground to complete the lateral transport of the object.

Benefit: Maximizes space usage and allows the handling of tall or large objects without compromising safety or functionality.

5. Precision Control

Advantage: Equipped with advanced control systems, including wireless remotes and variable frequency drives (VFD), the crane allows smooth and precise lifting, lowering, and movement of heavy loads.

Benefit: Ensures better handling accuracy, reducing the risk of load damage or accidents, and improving overall operational efficiency.

6. Enhanced Safety Features

Advantage: Overhead travelling cranes are equipped with multiple safety features such as overload protection, limit switches, emergency stop buttons, and anti-sway technology.

Benefit: Increases operator safety and prevents damage to equipment, loads, and personnel by ensuring the crane operates within safe limits.

7. Energy Efficiency

Advantage: Modern cranes are designed with energy-efficient motors and control systems, such as VFDs, that optimize power usage by adjusting speed and torque based on load requirements.

Benefit: Reduces operational costs by lowering energy consumption while improving performance and extending the life of mechanical components.

8. Customizability

Advantage: The crane can be customized to meet specific operational needs, such as varying lifting speeds, span lengths, lifting heights, and control options.

Benefit: Tailoring the crane to specific applications increases efficiency and productivity in unique environments, such as specific manufacturing processes or specialized material handling.

9. Space Efficiency

Advantage: As an overhead crane, it operates above the workspace, leaving the floor area free for other activities.

Benefit: This makes it ideal for facilities with limited space, allowing for better organization and maximized productivity by using vertical space for heavy load handling.

10. Minimal Floor Obstruction

Advantage: Since the crane runs on overhead rails, there are no floor-level obstructions, providing a clear and open work area.

Benefit: Improved maneuverability of equipment and personnel on the ground, enhancing workplace efficiency and safety.

11. High Efficiency in Heavy Industrial Applications

Advantage: Overhead travelling cranes are designed for continuous, heavy-duty use in industrial environments, offering consistent performance over long periods.

Benefit: Increases productivity in industries that require frequent, large-scale lifting operations, such as steel mills, foundries, and shipyards.

12. Reduced Manual Labor

Advantage: The crane's ability to handle extremely heavy loads reduces the need for manual lifting or the use of multiple smaller cranes.

Benefit: This leads to increased efficiency, reduced labor costs, and a safer working environment by minimizing the risk of injury associated with manual material handling.

13. Cost-Effective Over Time

Advantage: Despite the high initial investment, 150-ton overhead cranes are highly cost-effective over their lifespan due to their durability, low maintenance requirements, and ability to handle high-capacity loads.

Benefit: Long-term cost savings through reduced maintenance, lower energy consumption, and improved operational efficiency.

14. Adaptability to Harsh Environments

Advantage: These cranes can be designed to operate in harsh environments, such as high temperatures, dusty or corrosive environments, or outdoor conditions.

Benefit: Reliable performance in extreme industrial settings, such as steel plants or chemical industries, where environmental factors are challenging.

15. Improved Productivity

Advantage: The crane's ability to lift, move, and position very heavy loads quickly and accurately improves overall workflow and productivity.

Benefit: Reduces the time required for load handling operations, allowing for faster turnaround times in production or construction processes.

In summary, a 150-ton Overhead Travelling Crane offers a combination of high lifting capacity, durability, precision control, and safety, making it an essential tool for industries that require efficient and reliable handling of heavy materials. Its advantages include improved productivity, space efficiency, and long-term cost-effectiveness.
