U-Frame W/Handle Bolt “ SKU: 578 The Core Mechanical Sub-Assembly That Powers Every Lift, Pull, and Lower If there's one component at the heart of how your Lug-All ratchet winch hoist actually works, it's the U-Frame. The U-Frame W/Handle Bolt (SKU: 578) is the genuine OEM replacement sub-assembly that keeps your hoist operating precisely, safely, and at full rated capacity.

Lug-All The U-Frame is the pivoting sub-frame that houses and drives the ratchet mechanism with every stroke of the handle. The U-frame pawl is responsible for turning the drum by engaging with the teeth as the handle travels its arc ” it is a crucial component for the hoist to operate properly, and it undergoes frequent wear and impact during operation. The U-Frame itself is what carries the pawl, the pawl shaft, the reversing lever, and the spring assembly ” all of which depend on a structurally sound, properly fitting U-Frame to function correctly. Lug-All The frame must be free to move from side to side; if it is jammed out of line, it is subjected to undue stress from uneven loading and would not be free to move sideways, which is necessary to allow even wrapping of the cable on the drum. A bent, cracked, or worn U-Frame is not a minor inconvenience ” it's a safety risk that takes your hoist out of service. Hoists Direct This SKU 578 assembly comes complete with the handle bolt already included, as confirmed in the official Lug-All 4000-20 parts list, where the U-Frame W/Handle Bolt is listed as a single line item assembly ” part number 578. That means you get both critical components in one order, simplifying your repair and getting you back to work faster. Hoists Direct Lug-All hoists include a shear pin between the handle socket and U-frame that is designed to break if the hoist becomes overloaded, and a double interlocking pawl mechanism ensures that one pawl is always holding the load. The integrity of that protection depends entirely on a properly functioning, OEM-spec U-Frame. Joseph Fazzio, Inc.
