Material of Stacker

 

 

Stacker cranes used in warehouse or industrial applications are made of strong materials such as steel or aluminum. However, there are also stackers made of plastic or wood for lighter loads or for use in retail or domestic settings. Additionally, some stackers may have a combination of materials, such as a metal frame with plastic parts, for added durability and ease of use.

 

Three Basic Movements of a Stacker Crane

Luffing

This is vertical movement. Stackers use either a winch mechanism with metal wire, or hydraulic cylinders, generally two. Winch mechanisms are highly reliable compared to hydraulic actuators and remain widely used, particularly in large stackers.

Travelling

The stacker moves on a rail track, which may be broad or narrow gauge, enabling it to move around the stockyard as required. For this purpose, traction motors powered by direct current (DC) are connected by bevel gears to between 12 and 22 wheels. For manual control, all the controls are in a controller's cabin above the boom conveyor or boom. Modern stackers can be controlled remotely.

Slewing

This is rotation of the stacker around its central axis to align or place the stockpile where required. This works mostly by a slew pinion that rotates around a slew base. This type of gear assembly is called a sun and planet gear. The axles may be multiple and are driven by DC-powered axle motors which transmit the torque via bevel or helical gears.

The load capacity of a stacker crane is the maximum weight it can carry, so it is important to choose a stacker crane that can handle the weight of your products. Determine both the maximum load and the average load expected to be handled by the stacker crane.


Height and depth requirements:

Consider the vertical and horizontal clearance needed by the stacker crane to operate. It is important to choose a stacker crane that can reach the desired height and has the necessary depth to navigate the available space, taking into account the height of your warehouse, the height of the racking, and the depth of your storage bays.


Speed and acceleration:

Determine the desired speed and acceleration of the stacker crane. The speed and acceleration should be optimized to match your inventory handling needs and the layout of your warehouse.


Maintenance requirements:

Choose a system that requires low maintenance and is easy to maintain. This will help reduce the possibility of downtime and ensure that the stacker is always operating at peak performance.


Power source:

Choose a stacker crane that is powered by a suitable power source, based on your specific warehouse environment. A stacker crane’s power source can be battery, diesel, gas, or electric, among other options.

 

What is The Function of a Stacker?

 

 

A stacker is a large machine used in bulk material handling. Its function is to pile bulk material such as limestone, ores, coal and cereals onto a stockpile. A reclaimer can be used to recover the material. In the logistics industry, stacker cranes are often used in warehouses or distribution centers to move and organize goods on pallets. Stackers use hydraulic lifts or electric motors to lift and stack pallets together, maximizing storage space and efficiency.

 

 

Application of Stacker

Warehouse management
A Stacker is commonly used in a warehouse or storage facility to lift and move heavy loads of products, pallets, and containers between storage racks or shelves, transport goods to and from the loading docks, and stack items in a safe and organized manner.


Manufacturing industries
Stacker can also be used in manufacturing industries, especially in automotive and packing industries, to stack up raw materials and finished goods, load and unload containers, and move items along the production line.


Retail and distribution
Large departmental stores with multiple floors use stackers for material handling, stock control, warehousing, and distribution. They can easily stack the goods from the ground floor to the higher floors where the items are required to be placed.


Agriculture
In the agricultural sector, a Stacker can be used to lift and stack bales of hay, sacks of grain or seed, and other farm produce. This saves time and energy, and enables farmers and farm workers to work more efficiently.


Construction
This equipment is also used in the construction industry to lift and move heavy building materials like bricks, blocks, tiles, and cement bags at construction sites.


Ports and terminals
The use of Stacker equipment to unload and move containers in the shipping industry is essential since these containers are very heavy and require special handling. Stackers move these containers and stack them carefully according to size and weight.

Components of Stacker

 

Conveyor Belt:Stackers are designed with a conveyor belt that carries the material to be stacked or reclaimed. The conveyor belt can be straight or curved, depending on the stacking and reclaiming needs.
Boom:The boom is an essential component of a stacker. It is responsible for adjusting the height and position of the conveyor belt. The boom can move up and down and also rotate to stack material in a particular area.
Drive Train:Stackers have a drive train that includes an electric motor, gearboxes, and couplings. The drive provides power to the conveyor belt and the boom, allowing it to stack and reclaim material effectively.
Luffing System:The luffing system is used to adjust the angle of the boom. It is designed to allow the stacker to reach different heights and angles while stacking and reclaiming material.
Control System:Stackers are integrated with a control system that helps operators to control and manoeuvre the machine. The control system includes a programmable logic controller (PLC) and human-machine interface (HMI) to perform automated functions.
Slewing System:Stackers are designed with a slewing system that allows the machine to rotate around its axis. The slewing system is usually located at the base of the stacker and is essential for manoeuvring the machine in tight spaces.
Cabin:The cabin is an enclosed area where the operator sits while working the stacker. It provides the operator with a clear view of the stacking and reclaiming area and has all necessary controls and displays to operate the machine.

 

Working Principle of Stacker

 

The working principle of a stacker involves a conveyor system that moves the bulk materials from a receiving point to a discharge point. Stackers are high-capacity machines used for stacking and blending material. Working in two directions, a stacker can pile material onto two parallel stockpiles using a slewing and luffing boom. A rail-mounted stacker travels on two rails between the stockpiles. The stopping and starting sequence for the stacking operation is controlled either from the operator's cabin control panel or from a central control room.

 

How to Maintain Stacker
 

Regular Cleaning and Lubrication

Clean the stacker regularly to remove dirt, dust and debris. Lubricate the moving parts to prevent excessive wear and tear. Use a dry cloth to wipe down the stacker.

 

Check the battery

Check the battery for charge and water levels every day. Maintain the battery with distilled water and keep it charged. Make sure the battery terminals are clean and tightened properly.

 

Check Hydraulic fluid level

Check the hydraulic fluid level and top up if necessary. Perform regular checks for leaks. If the hydraulic fluid is contaminated or there is a leak, then it should be drained and replaced.

 

Regular Inspection

Inspect the stacker on a regular basis. Check the brakes, steering, and suspension. Replace any worn-out parts. Inspect the forks and chains for cracks and damage.

 

How Much Weight Can Stackers Lift?

Stacker cranes are designed to lift different weights depending on their model and specifications. Some stackers can only lift loads of 500 pounds, while others can handle loads up to 10,000 pounds. It is important to check the specifications and rated capacity before using a forklift to prevent overloading and potential accidents.

What Are Some Common Features of Stackers?

Stackers are designed to stack goods vertically, making efficient use of space. Stackers can be operated manually, with a person using a crank or lever to lift and lower the platform. Alternatively, they can be fully automated, using motors and sensors to move goods at the touch of a button. Stackers typically have an adjustable height feature that allows the platform to be raised or lowered as needed. This feature allows them to be used for a wide range of applications and makes them versatile. Many stackers have built-in safety features, such as safety stops, overload protection, and emergency stops. These features help to prevent accidents and injuries. Stackers often come with wheels or casters that allow them to be easily moved from one location to another. This feature makes them highly mobile and versatile.
