The Little Giant Instrument Cart with Writing Shelf and Storage Pocket offers practical features for enhanced functionality. The convenient writing shelf measures 21” wide by 12” long, while the sloped storage pocket measures 14” wide by 12-1/2” long with a 4-3/4” access height. Equipped with 9” pneumatic casters—two swivels and two rigid—it provides a cushioned ride over rough floor surfaces and is ideal for navigating small obstructions or outdoor applications. These pneumatic wheels offer excellent shock and vibration absorption, similar to automotive tires, and can easily roll over uneven surfaces and bumps. However, they require air pressure management and may compress under heavy loads, increasing rolling resistance. These wheels are perfect for handling fragile loads over rough terrain.
