Forklift

What is a FORKLIFT?

It is a powered industrial truck used to lift and transport materials by means of steel forks inserted under the load. it is most commonly used to move loads stored on pallets.


Characteristics of a FORKLIFT

A typical forklift may be generally described as follows:

- An LPG, gasoline or diesel fueled internal combustion engine, or an electric motor(s) either Direct Current or Alternatinig Current powered by either a battery or fuel cells.

- The mast, which is the vertical assembly that does the raising, lowering and tilting the load.

- The carriage, which comprises flat metal plate(s) and is movved along the mast either by mean of chains, or directly attached to the hydraulic cylinder.

- A load back rest is fitted when the load is higher than the top of the carriage.

- A driver's overhead guard that protects the operator from any falling objects

- The cab, which may contain a seat for the operator, along with the control pedals, steering wheel, levers and switches for controlling the machine.

- Counterbalance machine have a counterweight, necessary to compensate for the load.

Classes of FORKLIFTS.

\

Class I forklifts are electric-motor rider trucks, either stand-up operator or seated three-wheel units. Rider units are counterbalanced and may have cushion or pneumatic wheels.

Class II forklifts are electric-motor trucks for narrow aisle or inventory stock/order picking applications. They may have extra reach or swing-mast functions.

Class III forklifts are electric-motor trucks, either walk-behind or standing-rider operated. Automated pallet lift-trucks and high lift models are often counterbalanced.

Class IV forklifts are rider fork trucks, with cabs and seated controls, internal combustion engines, and solid or "cushion" tires.

/

Class V forklifts are rider fork trucks, with cabs and seated controls, internal combustion engines, and pneumatic tires. Like Class IV forklifts, they are typically counterbalanced.

Class VI forklifts are sit-down rider, tow tractor lifts. They are supplied with electric or internal combustion engines.

Class VII forklifts are designed for use on rough terrain. Typical applications include agriculture, logging and construction.

Class VIII forklifts include all personnel and burden carrier.

Turret Truck

Turret Truck
Very narrow aisle truck (VNA) allows storage of pallet loads in racking with aisles less than 6' wide. Man-up design facilitates accurate placement in tall racking (up to 40 ft.). This type of vehicle generally requires a guidance system and extremely level floors. One features of turret truck is a fork mechanism that rotates 180 degrees, right or left, to work either side of the very-narrow aisle. The rotating mechanism is what gives the truck its VNA capability. Both Man-down and man-up turret truck models are used in the industries.

Operator-Down Turret Truck
Operator not lifted with the load
5-6 ft. minimum aisle width requirement
Termed a swingmast truck (picture shown) when, instead of just the forks, the entire mast rotates (thus can store on only one side of a aisle while in aisle)
By using Operator-Down Turret Truck, there is greater vehicle stability and the cost is also cheaper than Operator-Up Turret Truck
However man-down operators may need load-positioning, shelf-height-indicating sensors, or special racking to assist them in load movements in pallet bays above the fourth or fifth level as visibility to the top of the rack becomes a potential concern.

Operator-Up Turret Truck
Operator lifted with the load to allow precise stacking and picking
5-7 ft. minimum aisle width requirement
Some of the advantages that Operator-Up Turret Truck offers includes allowing the operator to gets a bird's eye view. This can result in having less damage to product, pallet, and racks.
However riding up to the load level in a man-up truck and working some 40 ft above the floor presents some risks. Thus the operator is tethered to the vehicle with a safety harness.
It is proven in the industry that turret trucks perform most productively within the aisle. However, once the truck moves outside the aisles, you may want to have pickup stations for load transfers to handling by counterbalanced trucks, to conveyor, or to other delivery and takeaway methods. This is so as it does not make much economic sense to have the turret truck and its operator doing work outside the VNA racking when it can be done by a counterbalanced truck which cost very much cheaper.

Reach Truck

A narrow aisle (8'-10') truck designed specifically for racked pallet storage. It consists of outriggers in front and telescoping forks that use a 'hydraulic scissors' type of mechanism which allows you to pick up the load and retract it over the outriggers, reducing the overall truck and load length, thus allowing you to turn in a narrower aisle


Profound? In a nutshell, this equipment:


-Harness the full potential of warehouse operators.

-Moves, store and retrieve pallets as efficiently as possible.

-Optimize the productivity of operators with such equipment that puts them in full control of every load, everytime.


Yes, we are talking about the Reach Truck.



Some pictures are them appended below:

The reach truck is undisputedly one of the common types of material handling equipment that can be found in the warehouse. Basically, as given its name, it 'reaches' out to racks that can be up to 5 high in height. It saves tons load of energy having to transfer pallets up and down the racks and can be relatively easy to use as well.

Driven around almost like a normal vehicle, operators can manoeuvre its way around the warehouse without much fuss, given its small machinery size. They come in many different kinds of model, some equipped with sophisicated technologies such as anti-brake system, power steering and all sorts. Most ones we typically see in warehouses are probably the ones that enable the operators to seat while doing their job. However, there are also reach trucks that allow the user to stand while operating the machine.

Here are some more pictures to provide a more definite illustration:



'Look at how well the dude fits into the truck, totally awesome!'

Pallet Jack

Pallet jacks are perhaps the easiest to use among all the equipment in the warehouse. They are used to lift and transport pallets around the warehouse. The limitations of pallet jacks is that they can only lift a pallet high enough off the ground to allow the pallet to be transported. Therefore, for binning or retrieving purposes from high shelves, appropriate equipment such as an order picker is still needed.

There are many types of pallet jacks with different functions. This post will cover two of the most widely used pallet jacks.



The first type is the conventional type which is normally used in warehouses. It serves basic functions like lifting of a load and moving it around the warehouse. Different sizes of pallet jacks can withstand different loads. For example, a smaller jet can hold a maximum weight of 1000kg while another pallet jack with a wider distance between the forks can hold a maximum weight of 3000kg.

The second type of pallet jack is one which has an inbuilt weighing scale. After a pallet of goods have been shrink-wrapped and waiting to be shipped, a shipping mark has to be attached to the pallet stating the ship-to address. Other essential information to be included in the shipping mark includes the physical dimensions of the carton, as well as the weight of the entire pallet. Thus, using the pallet jack with weighing functions, the trouble of lifting the loads up and down the weighing scale can be avoided.








More examples of pallet jacks with a built-in weighing scale can be seen in the link below -->

In most warehouses, there are usually two sections namely the incoming and the outgoing. Incoming would be doing the receiving and binning of goods while the outgoing team would be doing the picking and packing of goods. Therefore, warehouses normally do not require too many pallet jacks with weighing functions. This is because operations of the incoming team as well as the outgoing team in charged of doing picking do not require the use of a pallet jack with weighing function.
