Poly Spring Lift Kit
The basket truck spring lift is a platform that brings your work up to a safe and convenient height, so you don't have to strain your back reaching for the bottom of the basket for light materials. Its extra strong springs are covered, and replacements can be purchased separately. Note: maximum weight capacity is the lowest weight capacity of either the cube truck or the spring platform lift.
