For my internship and final year project, I am being attached to Menlo Worldwide Asia Pacific Pte Ltd and Yusen Air and Sea Service(S) Pte Ltd respectively. Both are 3PL companies and the pictures below show the material handling equipment used by them. The equipment are being catorized into the 5 groups of MHE for easy understanding.
[1] Transport Equipment
Forklifts (Gas/ Electric) - Gas forklifts can be refueled quickly and easily, but they require storage for the fuel, and the fuel can become expensive. Even though gas forklifts are less expensive to purchase initially, the cost of fuel quickly adds up, making them most expensive per use than electric. They can never be used indoors because of their toxic emissions and fear of carbon monoxide poisoning. Gas forklifts can handle larger loads and can be used for minor pushing or towing as well. And as for electric forklifts, batteries are installed in them. The batteries are usually designed to last for at least one standard shift before needing a recharge, and the recharge station must be in a dry, well-ventilated area. Electric forklifts are quiet and inexpensive (low operating cost) as they do not need storage area for gas or diesel fuel.

- Stacker - Its ''forks'' are able to reach higher than a forklift to store or retrieve a single pallet of goods from the pallet rack (above 2 levels).

- Pallet Jack - It is a tool to raise or lower a single pallet simply to provide clearance from the floor for manual (hand) pulling.

- Order Picker - Similar to a forklift except that the operator can rise up to the load to collect the items and place them on the pallet lifted by the ''forks''. However, the operator is proned to falls thus has to put on the safety belt.


- Order picking trolleys

# Trolley with steps to retrieve items at slightly above height.
# The conveyor belt connects the kitting area to the packing area.

- Omni Lift - It make use of a conveyor belt system and to vertically lift single pallet of goods up to any storey of the warehouse. It provides fast movement of goods, eliminating time to send the goods through the cargo lift, thus make the warehouse operations more efficient whenever there is receiving or shipping of goods.

# Omni lift at level 1 - Goods are being placed on the conveyor...


# Omni lift at level 3 - ....and arrive at the 3rd storey.
[2] Positioning Equipment
- Dock leveler
[3] Unit Load Formation Equipment
- Metal Drums

- Pallets (wooden/plastics) and cartons


- Wooden crates

[4] Storage Equipment
- Automated Storage Retrieval System (ASRS) - It provides a fast way of storing and retrieving goods with the minimun effort, time and errors. To put-away, the system will check for empty locations in the racks in the computer. A pallet at a time will be placed on the conveyor belt. Choose the location for storage and after all items are being scanned, the automated crane will pick up the pallet and be directed to the appropriate aisle to store the pallet of goods into the empty location. For retrieval of goods, simply scan the picklist and the automated crane will proceed to pick all the required items and place them on the conveyor.

- Pallet Rack (also known as "Heavy-Duty Rack")

[5] Identification and Control Equipment
- Barcoding 1 (Linear Barcode)


# Items are being scanned for their serial numbers during the packing stage before shipping out to the customers.



# The 2D barcodes are able to encode much more highly detailed information than linear barcodes, making it a more acccurate and efficient to track inventory from the unloading dock to the end-users.
When goods arrive, to put-away, the material handler will scan the product before scanning the barcode on the rack so that the system will capture the location of the stored goods. For order picking, the picker will scan the barcode on the picklist. From the screen of the 2D scanner that shows the items to be picked, their quantity and locations, the picker will proceed to the location to scan the each all the required items after being picked.
