Abstract
A crank handle (40) which is used in a roll-up flexible cover assembly (64) for an open container, such as a truck (68), includes a longitudinal tube (42) and a rotatable tube (44). The rotatable tube (44) has a longitudinal portion (46) being telescopically disposed in the longitudinal tube (42). The rotatable tube (44) is adjustable among a stored location, an adjusting position, and a working location. The crank handle (40) is extended at the working location, so that the operator can stand away from the side of the truck (68) and easily operate the crank handle (40). The crank handle (40) is retracted to the stored location, preferably on the side of the truck (68). The rotatable tube (44) of the crank handle (40) is turned to a desired direction at the adjusting position so that the crank handle (40) can be vertically stored in a desire location.
