摘要: Transport apparatus utilizing a carrying strap permitting one individual to load and transport roll of sheet plastic material without damage. The utilizes three upwardly directed equally spaced U-shaped supports, A supporting base for the center support is arranged permit placing on planar surface loading. attached through locking extension with number outward positions eliminate damaging during end supports telescopically accommodate different length rolls, which lock at various lengths ensure positive support. Pivots telescopic attachments pivoting together minimize storage space.
