Product Overview

The DAT HOIST 12ft Subframe Kit is engineered to provide a strong, stable foundation for dump bed installations using DH-520 and DH-520HD hydraulic scissor hoists.

Manufactured from high-strength steel and reinforced at critical load-bearing points, this product includes the subframe structure and mounting components only. It is intended for customers who already have a compatible DH-520 or DH-520HD scissor hoist or plan to source the hoist separately.
