MODULE 10 Storage and handling equipment Flashcards
“The best handling solutions involve the least handling.Handling adds to the cost but not to the value of the product.”
(Linde Materials Handling)
True
The greater the storage an operation requires, the greater the density of pallet storage needed.
True
The trade-off is the fact that these systems take longer to access and deposit pallets and may require specific handling equipment or a different type of racking
True
Wide aisle adjustable pallet racking on the other hand doesn’t takes up more floor space but products are easier and quicker to access.
False
Takes up
The type of storage will depend on the configuration of the building, the type of MHE currently in use and the budget available.
True
Block stacking is the most common method of storing large quantities of single SKU products.
True
Damage - Sufficient space needs to be allocated for forklift trucks to access each stack.
False
Access
Access- The items at the bottom can be crushed by the weight of the items above
False
Damage
Stock rotation. Unless product can be accessed at both ends of the stack, items can only be despatched on a LIFO (last in, first out) basis.
True
Space utilization. Utilization can be very poor if stock does not move quickly through the warehouse.
True
The use of pallet collars and converters can reduce the potential damage to underlying pallets and increase the stack height
True
The terms adjustable pallet racking (APR) and wide aisle racking (WAR) are not seen as interchangeable.
False
Seen
Wide aisle or selective pallet racking is not present in the majority of warehouses worldwide, most versatile of any racking
False
Present
Double-deep pallet racking, as the name implies, allows pallets to be stored two Shallow in the racking thus eliminating an aisle
False
Deep
By adding the number of access aisles and using the space saved to accommodate additional racking, a double-deep configuration provides a highly space-efficient storage system.
False
By reducing
Narrow aisle racking, as the name implies, utilizes APR and provides storage for greater concentration of pallets by reducing the aisle width to circa 1.6 metres
True
The trucks are manoeuvred within the aisles via wire-guided systems or guide rails.
True
The use of guide rails does not prevents the use of powered pallet trucks in this area to pick up and deposit pallets in the pick face as they are unable to access the pallets.
False
The use of guide rails prevents
Narrowing the aisles too much restricts the speeds at which a forklift can travel between picking locations.
True
The use of articulated trucks in narrower aisle racking means that different aisle widths can be achieved but without the need for wire-guided systems or guide rails and a perfectly flat floor
False
Similar
Drive-in racking provides a safe and efficient equivalent to block stacking for loads that are too fragile or unstable to be stacked on top of each other
True
Drive-in racking allow for first in, first out (FIFO)
False
Does not
Drive-in/drive-through racking is a high-density storage medium suitable for large quantities of single SKUs.
True
Its advantages are the increased potential for damage
False
Its disadvantages are the increased potential for damage
Drive-in/drive-through racking can be used at the despatch area to stage outgoing pallets by truck, reducing the amount of floor space required in this area.
True
Pallet-flow racking is driven by gravity
Push-back systems work by placing pallet loads on a series of nesting carts fed forward by gravity on rigid structural steel rails
True
in mobile racking floor space is being saved at the expense of a slowing down in the load-retrieving operation.
True
The shuttles are controlled remotely via a radio frequency (RF) battery-operated control system and special channel rails.
True
Multiple shuttles can’t be controlled by one forklift truck.
False
Can
Satellite racking can also utilize the space above the loading bays.
True
The ACTIV System can buffer, sort, and stage palletized unit loads in exact loading sequence.
True
Very high bay warehouse consist essentially of massive blocks of racking, built as an integral structure to a high degree of precision, and often acting as a support for the building’s roofing and wall cladding.
True
Cantilever racking is an ideal solution for long or heavy items such as pipe storage, timber, carpet or furniture storage.
True
Where a warehouse has sufficient height it can be very cost effective to construct a mezzanine floor.
True
An HPT has a hydraulic pump to enable the operator to lift a pallet sufficiently to be able to move it across the warehouse floor.
True
These are battery operated and are used for loading, unloading, picking and pallet-transfer duties to and from the receiving and despatch areas
True
Tow tractors/tug are utilized where distances between points within the warehouse are long and there is a requirement to move a number of pallets at the same time.
True
Using special reflective surfaces placed throughout the facility, the automated laser-guided vehicle continuously checks its position and path as it is controlled by the WMS.
True
In order to take advantage of the cubic capacity of a building, pallets or unit loads need to be lifted into position.
True
Pallet or ‘Walkie’ stack are used for moving pallets around the warehouse and when required can lift pallets up to 5 metres. They can be pedestrian, ride-on, stand-in or seated
True
CBTs are the most common trucks to be found in a warehouse. They are fast, flexible and versatile, They are powered by diesel, battery, LPG or CNG. They can operate inside and outside the warehouse.
True
Reach trucks are not ideal for working within narrower aisles
False
Ideal
Narrow aisle or turret trucks are designed to operate with little more aisle space than their own width.
True
Articulated forklift trucks load and unload vehicles and deliver pallets directly to the racking in a single operation.
True
Automated storage and retrieval systems
(AS/RS) utilizes fixed path cranes to collect pallets at the front of the racking system and transport them to empty locations within the racking
True
all unit loads can be moved or picked up by standard pallet forks.
False
Not all
The new fork-based scanning process not only results in significant time savings compared with manual scanning, but reduces the forklift driver’s workload and ensures low picking error rates.
True
