William Sardo Pallet Lab


William H. Sardo Jr. Package, Pallet, Unit Load, and Container Research Laboratory





Vertical Linear / Random Vibration Table

Drop height range: 12in x 60in

Max package size: 36in x 36in



Swing Arm Drop Tester:

Maximum package weight: 150lbs

Drop height range: 12in x 60in

Max package size: 16in x 12in






Compression Testers



Tinius Olsen

Payload capacity: 25,000lbs

Platen Size: 60in x 72in

Load applicator: fixed platen, air-bag

Maximum unit load height: 9 feet



Description

The Tinius Olsen Compression Machine, with a load capacity of 40,000 lbs., a platen area of 30 square feet and a maximum clearance between platens of 9 feet, is ideal for evaluating an individual container and an entire pallet load of containers. This compression machine has an electronic load holder that maintains a fixed compression load on a container for as long as desired.





Lansmont Squizer

Payload capacity: 5,000lb

Platen Size: 30in x 30in

Load applicator: fixed platen

Maximum package height: 3 feet



Description

The Lansmont Squizer compression test system quantifies box performance so that the effect of various board mediums, closures and interior partitions can be compared by means of "load sharing" analysis. Production line variations can be easily benchmarked against design standards.





Custom Pallet Tester

Payload capacity: 10,000lb

Platen Size: 48in x 40in

Load applicator: air-bag



Description

This pallet tester evaluates the strength and stiffness of pallets. The load is applied with an airbag to produce a completely distributive load. The glass windows in each side control the temperature during the test. This way, we can test pallet behavior in different environmental conditions.





High Performance Compression Testers:

Other than the compression testers above, we also have access to high performance compression testers with maximum capacity of 1,200,00lbs.

Load cells: 1,000lb, 5,000lb and 20,000lb

Type of mechanical tests: tension, compression, cyclic and fracture



Description

This is a servo hydraulic system. The system is used in various ASTM test. We have several types of fixtures for the unit. They include 3 and 4 point bending, tensions grips, and shear grips. The unit can also be used to do a cyclic fatigue test.





Environmental Test Chambers



Chamber 1

Built by: Environmental Specialistsb

Size: 10' x 18' x 7'

Relative humidity: 45% to 90%



Description

This chamber is maintained at a constant 20°C and 65%Rh. This is to obtain an EMC of 12% in our wood samples.





Vertical 30ft3 Chamber with Desiccant Dryer

Model: #9135-8114DT

Temperature range: 7° to 85°C (44.6° to 185°F)

Relative Humidity Range: 10% to 95%



Description

This chamber is used to condition samples before testing and to simulate changing weather conditions.





Shock Tester

Carriage Size: 10in x 10in

Payload capacity: 30lbs

Carriage fall: 42in

Max. Acceleration: 3500G

Min. Pulse Duration 0.3ms

Description

Our shock tester is used to evaluate and design rugged products (such as electronics) and protective shipping packages. It produces half-sine, sawtooth, and square waves pulses meeting military (MIL-SPC) and industrial (ASTM, ISO, JEDEC) specifications.





Fast Track Area


Description

To test a palletized unit load for durability and economics of use, we simulate rough handling. This can be achieved by accelerated rough handling using devices employed in material handling. An example of such a test is found in ASTM D1083. To follow is a protocol developed and used at the Center for Unit Load Design of Virginia Tech. This is a modification of a test protocol developed by the Procter and Gamble Company to simulate the use of pallets in the grocery dry goods industries. The test simulates idle pallet storage, palletizing, shipping, transport, receiving, and three types of storage: static rack, flow rack, and block staking.
