Gantry: A Detailed Analysis Of Their Mechanism & Applicability In Modern World

Gantry

Gantry Robot System

Today’s industrial sector is growing at a faster pace with the introduction of carefully engineered robots and automation processes. These mediums have led to a revolutionizing step into the manufacturing industry.

These robots have changed manufacturing and assembling styles in terms of complex industrial products. They have made professional’s work easier and are widely used in sectors of pharmaceutical, automotive, food industry, biotech, etc.

What Does Gantry Mean?

A Gantry robot has a customized manipulator rolling above the overhead system in a horizontal direction. They are referred to as Cartesian robots, as well.

This robot has a stationary momentum on the roller or the overhead system. Every operation by the Gantry on this overhead is in a linear motion. At a stretch, we can find a minimum of three styles of bases for a Gantry robot.

These bases can be measured as X, Y, and Z for the ease of further readings by engineers working on the assembly lines.

Honestly, the Gantry robot systems are a slightly modified version of Cartesians. Where, on the one hand, Cartesian robots have used only one axis as a base, the Gantry robots are found to be using two X-axis as the base.

But these axes as bases can be changed to more than three at a time-as dimensions of the robots are increased to carry heavier put and place operations, assisting the engineer.
It is mostly known to be mounted above the mechanism, which is called the overhead Gantry. But there are cases when the Gantry robots are not useful from above.

This case can be related to solar cells as a prime example. Then, these robots are placed under the belt of the overhead Gantry.

Interestingly, where Gantry robots are famous for carrying out heavier and bulky tasks, they are also quite prominent in supporting the functionalities of compact machines.

What Is A Gantry System?

The Gantry robot system has a standardized configuration process. These systems can vary and have many combinations of the axes: X, Y, and Z.

This depends on industrial purposes and to meet the engineering & manufacturing operational needs for service providers like ALIO Industries.

For better knowledge, some combinations of this system are discussed below, along with their applicability:

System one:

It will have two X-axes and a single Y-axis. This module is capable of putting and placing faster peripherals and machinery components over a long trail of the overhead. It might be able to pick up moderate to heavier components at once.

System two:

This module will comprise of two X and Y axis. This Gantry robot system is utilized for heavy loads, and the second Y-axis can help push up the capacity of the robot to carry the load, and that too, over longer trails.

Otherwise, engineers make use of the second Y-axis for increasing the traction force by joining it with the drive shaft.

System three:

With two X-axes and a single Z-axis, this robot focuses on levying higher thrusts onto the vertical planes. For this purpose, engineers can manipulate the motion through ball screws.

System four:

With double X and Y axes, and a single Z, the linear motors help to boost the move along the horizontal axis for X and Y planes. Whereas, vertical cylinders help to guide the acceleration of the Z-axis.

When the Z-axis retracts, the whole mechanism of this Gantry robot helps to pick up and place a very heavy load from one position to another, which is also a very lengthy distance, in comparison to other systems.

What Is A Gantry Hoist Used For?

A Gantry hoist is one of the many lifting mechanisms that can be used on various and wider assembly lines and other engineering processes in large and updated organizations like ALIO Industries.

However, some of its prime uses as follows:

To move away the load

The biggest cranes or fully Gantry hoists are used at the industrial and construction level for picking and moving away heavy loads like metal sheets and debris. Other examples are containers, oil rigs, etc., to be moved away to declutter decks and ports.

To weight the different loads on the assembly line:

Smaller Gantry hoists are used to know the exact weight of the load by carrying with precision algorithms. It actually replaces big lorries and weighing machines. Hence, it ends up saving a lot of industrial factor costs.

For increasing mobility:

The hydraulic and linear motion-controlled Gantry hoists are best for increasing the motion along the assembly line or at a construction site.

When one component or material is displaced from one location to another, the next processes can be kicked in line to speed up the overall manufacturing or construction methods.

To promote versatility:

Gantry hoists are one of the most trustable mechanical tools promoting versatility. These Gantry hoists have several combinations through which every organization can carry out much-needed deliverables on time.

Other than these applications of the Gantry hoist or crane, it is also used widely inside the factories or plants like:

  • Warehouses
  • Garages
  • Manufacturing plants
  • Repair & Maintenance factories
  • Workshops

How Does A Gantry Crane Work?

The whole system of the Gantry crane works because of its components mentioned below with their usage in the whole mechanism:

Frame:

The structural frame provides sturdiness and strength to the overall pick and place robotic mechanism. It’s generally made from steel or aluminum.

Home Position Sensors:

Fully adjustable sensors help to correct the movement on the payload or the overhead horizontal line. This leads to the precision and accuracy delivered by the Gantry overhead.

Linear Motion Modules:

They are the crucial components of this whole says that help to drive the motion of the Gantry along a single axis. Without these driving modules, the Gantry robot wouldn’t even work.

Gear Reducers:

They help to facilitate the motion from servos and reduce any momentary inertia that’s caused or left behind.

Servo Motor Systems:

These motor systems are responsible for closing the loop of the whole mechanism form the controller to the endpoint. It helps to convert the signals and let the motion driver know that the motion has been carried out as planned.
