摘要： A mountable roller device for ladders. It is capable of integrating and attaching to step ladders, extension ladders, or most other standard ladders. The mountable roller device has a pair of side latches for connecting to the legs of the ladder, and also includes a plug for inserting into the void within the ladder steps of a typical ladder. Once affixed to the ladder, the ladder can be tipped and rolled along the roller wheel of the device. The roller wheel includes a groove to allow the device to be used as a pulley system with the ladder.

摘要： A ladder support assembly including a base frame having first and second ends and a pair of pivot supports extending from the base frame which support a rod configured to pivotally support a ladder relative to the base frame. A pivot frame is pivotally mounted to the base frame and is biased away from the base frame. A bracket assembly is pivotally mounted to the pivot frame and includes a pair of bracket plates. Each bracket plate has an inner flange and outer flange with a ladder rail receiving area between the inner and outer flanges. The ladder receiving area is configured such that the bracket plate is slidable relative to a respective ladder rail received therein. A crank assembly includes a spool rotatably supported on the base frame and a cord wound about the spool with a free end of the cord connected relative to the pivot frame.

摘要： A storage system includes a plurality of shelves, an aisle and a plurality of ladders. The plurality of shelves includes a pair of fixed shelves and at least one mobile shelf located between the pair of fixed shelves. The aisle is selectively configured to be located between two of the plurality of shelves. The plurality of ladders are spaced apart from and stored at an end of the at least one mobile shelf for slidable access into the aisle. Each ladder engages with a pair of fixed rails that span at least a length of the fixed shelves. A number of ladders correspond with a number of selectively defined aisles.
