• Dump Cycle Integrity — Provides the positive stop that controls skip/hopper travel at full dump, protecting the frame and hydraulic components from over-travel stress.
• Verified Part Number — Order with confidence using Multiquip part number 512279, cross-referenced to the Whiteman WBH and WTB series parts documentation.

The bum stop support is the structural bracket that limits and cushions the hopper or skip at the end of its dump arc on a power buggy. When the operator tips the load, this support absorbs the impact and holds the hopper at the correct maximum angle, preventing metal-on-metal contact that could damage the frame or hydraulic cylinder. A worn, cracked, or missing bum stop support leads to uncontrolled hopper travel, increased stress on surrounding components, and potential safety hazards during the dump cycle.
