The Future of Forklifts

What is the future for forklifts


There are two schools of thought on the future of forklifts. Some believe that forklifts will continue to be in production and demand will be stronger than ever, but some believe that forklifts will eventually become obsolete. What role will the forklift play in the future then?

With the increase in sales of forklifts over the last few years, many believe that forklifts are here to stay and that it will still remain an essential tool in the warehouse. They foresee a technological advancement in the forklift – from the human-operated forklift to the automated intelligent forklift. This new breed of forklift can be programmed to pick specific pallets and deliver them faster and safer than human-operated forklifts. RFID tags can be placed in high traffic areas signaling the forklift to slow down and not to exceed a set speed. Several ergonomic risk factors such as awkward neck and back postures and climbing up and down the forklift itself throughout the warehouse will be eliminated. The automated forklift can help in manual material handling as well. For mixed-pallet picking, the automated forklift will pull the pallet from shelving and bring it down into the optimal manual material handling zone for the operator to then transfer products, thereby eliminating the need for operators to pick products from the ground or above the shoulders. Additionally, automated forklifts are outfitted with a real-time location system that eliminates the need for frequent manual scanning of the load.

However, others believe that forklifts will eventually become obsolete as warehouses are moving to more automated storage and retrieval system. As this technology and robotics improve, it has become faster and cheaper to make use of this automation in the warehouse. Using barcodes and scanners (or similar technologies), these robots can accurately select inventory, or entire pallets of products, move them to a new location, and update information in the inventory system. This equipment can interface directly with Production, Shipping and Inventory systems. Technology in the warehouse can now instantly receive a customer order, find the correct shelf or bin, pull the necessary number of items, and place them with other ordered items for shipping. Once the packing is complete, an Automated Guided Vehicle (AGV) can take the box to the truck. Forklifts won’t be needed in any part of the process since AGVs are basically self-driving forklifts.

Though we will not be sure of what role forklifts will play in the future, there is no need to worry yet. While automated picking systems may have started replacing the forklift in some warehouses, forklifts are not likely to vanish from the warehouse tomorrow, especially not in smaller warehouses. Industry players still foresee forklifts containing more advanced on-board technology that will improve operator productivity and enable connectivity and automation. This will also see increased forklift connectivity that provides greater visibility into warehouse environment, operator productivity and product movement.

Components of Forklift

Parts of a forklift

Locating the common parts of a forklift is vital to ensure that your operators are reliably using equipment as intended in a safe manner. The following list of forklift terminology will help to identify items that require the attention of a maintenance technician. The forklift has many components, and this article aims to provide a brief introduction to them. The components of the forklift include:

–              Steering Wheel: To drive the forklift left or right

–              Counter Weight : The weight installed by the manufacturer to give stability to the machine            under load.

–              Tilt Cylinder : Controls the amount by which the mast structure, forks and carriage may be             tilted beyond the vertical position, forward or backward.

–              Fork : The cantilevered arms attached to the load carriage, that engage the load.

–              Carriage : A support structure where the forks are attached or mounted.

–              Back Rest : Attached to the carriage and prevents the load from shifting backwards. It also             protects the mast cylinders hoses, to prevent any goods falling through the mast and hitting the operator.

–              Lift Cylinder : Controls the amount by which the mast structure, forks and carriage may be             raised or lowered in the vertical.

–              Mast : The mast is the vertical support that allows you to raise or lower the load.

–              Overhead Guard : A framework/roof, providing overhead protection for the operator from            falling objects.

–              Rating Plate : This is used to inform users of the maximum load a forklift can legally carry.

–              Operator’s Seat

–              Steering / Rear wheels

–              Drive wheels

–              Lights and Horn

Forklift Hydraulics Control and Capabilities

Forklift control and hydraulics

Forklifts derive their power to lift thousands of kilograms from two intertwining mechanisms: a pair of hydraulic cylinders and a pair of roller chain pulleys. The lift handle is wired to an electrical air pump at the base of the machine such that when it is pressed, the handle will activate the air pump, which draws in outside air through a filter and forces it into a tube leading to both hydraulic cylinders.

A hydraulic cylinder consists of a hollow tube sealed at one end with a movable, lubricated piston fitting into the other. Air enters the bottom of the cylinder through a special “one way” valve that allows gases to enter without leaking back out. As the amount of gas in the cylinder increases, so does the pressure inside it. This pressure, applied across the area of the piston head, results in a net upward force. This upward push causes the piston to move up, which increases the volume of the gas and decreases the pressure. This automatically leads to a physical equilibrium where, at a given lift height, the force from the gas equals the downward force of the forklift’s load.

In order to move the load higher, the operator will have to push the handle forward. This would signal the machine to pump more air into the cylinders. To lower the load, the operator pulls the handle back, which triggers a special valve to gently release gas from the cylinder.

The hydraulic pistons are attached to the two main vertical structures called the “masts.” However, the actual forks that carry the load are attached to the main body of the forklift through a pair of roller chain pulleys whose fulcrum is a gear at the top of the mast.

Hence, when the hydraulic pistons push the masts up, the gears on the masts will push against the roller chains. Because one side of the chains are attached to the immobile frame of the forklift, the only way the masts can move up is if the gears rotate clockwise and pull the forks up.

The importance of this mechanism is that it allows the forks to go far beyond the reach of the cylinders alone. If it weren’t for the roller chain pulleys, forklifts would need much taller cylinders to lift loads to a comparable height. Taller cylinders would mean more building material, which would shift the vehicle‘s centre of gravity forward and increase the risk of tipping. Likewise, taller cylinders would demand stronger pumps and higher pressure thresholds.

Forklifts have two sets of controls: one for steering and one for lifting. The steering controls work much like those of a golf cart: acceleration pedal, brake, steering wheel, forward gear and reverse gear. However, unlike a car or golf cart, forklifts use rear-wheel steering–when you turn the steering wheel, the wheels on the rear axle turn back and forth. This design is intentional: rear-wheel steering allows the driver a greater degree of rotation and precision when handling a load.

The lifting controls consist of two levers: one for lifting the fork up and down as well as one for tilting the load back and forth. The lifting functionality works as discussed above–forward moves up and backward moves down. The tilting functionality, however, is slightly different. At the base of the masts are two pairs of additional hydraulic cylinders that attach to the base of the vehicle. When the “tilt” handle is moved forward, air is pumped into the chamber. This increase in pressure pushes the piston head and causes the masts to “lean away” from the vehicle’s body.

When the “tilt” handle is moved back, air is slowly released from this cylinder as air is pumped into the other pair of mast-attached cylinders. When the pistons from the latter pair push forward, the masts are rocked back toward the vehicle. Learn more about forklift, click here.

Advantages of the Forklift

The advantages of forklift in Singapore.

A forklift (also called a lift truck, a fork truck, or a forklift truck) is a powered industrial truck with a pronged device in front for lifting and carrying heavy goods and supplies from one place to another. The forklift can be used for stacking materials in the warehouse, shipping depots, storage facilities, etc. Without these machines, the warehouses would not be able to operate efficiently and smoothly. Some forklifts are built so that they are small and compact, as they are designed to work in tight and narrow areas. They are highly maneuverable and are capable to lift different weights of loads, some reaching even up to 5000 kg. The best thing is that you can choose a forklift with the right configuration and capacity depending on your needs.

One advantage of the forklifts is that they are capable of reaching items located on high locations. They have great lifting capabilities. No longer will you have to use ladders or the pulley system. The forklift can be said to help many warehouses optimize the warehouse space. This is because storage can now be built upwards, and the items are accessible by the forklift.

Another advantage is the ease of maintenance. Forklifts with simple operation and maintenance can easily be sourced out. Proper and regular maintenance is essential for ensuring a long service life, and it is very important for keeping the machine in a good working condition. Your forklift supplier should be able to help in providing a full maintenance and preventive maintenance plan.

With the advent of technology, there is also increased safety in the forklift. Before forklifts became available, people who worked in warehouses and factories were using simple and customized systems for lifting and moving loads, such as ropes, cables, pulleys and other combinations. These required a lot of manual labour and supervision, and these mechanisms were also not safe. Forklifts today are very improved and they increase the safety of all the operators and workers involved.

Some systems can also work together with the forklift to help measure the weight of heavy items. This is important in some industries, for example the recycled metal industry. After using a trailer to collect all the recycled metal parts, the forklift can be used to unload the metal parts to the desired location, and also to weigh them. The weight is multiplied to a per kilogram unit cost, which will then be the amount paid to the supplier of recycled metal.

Businesses therefore thrive with the use of forklifts, and is thus a machine that is indispensable. The amount that it often helps businesses to cut costs and to generate revenue is one that cannot be underestimated. Learn more about forklift, go here.
