What is this?

• A. Self dumping bin
• B. Tipping hopper
• C. Bale handler
• D. Trash chute

Answer: (A)

A self-dumping bin is a container that unloads its contents by tipping, under control of the crane or lifting equipment. It features a hinged bottom and a release mechanism so the operator can trigger the dump and let gravity do the work, which is ideal for quickly unloading bulk materials or debris without manual handling. This fits the item described because it’s a bin that dumps its load itself when released, not something that requires external tilting or separate machinery. A tipping hopper, by contrast, is usually a stationary or externally tilted device; a bale handler is built to grab and lift bales; a trash chute is a vertical waste conduit, not a mobile dumping container.
