Abstract: A plant processing system includes a mobile cart with a support rail, a rack with a rack rail, and a hanger configured to support one or more plants therefrom. The hanger is hangable from either the support rail or the rack rail. The hanger includes a first end having a hook deigned to engage either the support rail or the rack rail. A second end of the hanger includes a tab having a magnet that engages either the support rail or the rack rail to limit movement of the second end of the hanger. A series of crossbars can be attached to the hanger at select locations along the length of the hanger. Each crossbar is configured to support plants or other items along the length of the hanger.

Abstract: A brake arrangement is provided for a mobile storage unit having a drive arrangement for causing movement of the mobile storage unit. The brake arrangement has a brake member mounted to and rotatable with a drive shaft of the drive arrangement, and acts on the drive shaft when the input force on the drive shaft is relieved. A flexible band is engaged with the brake member and defines a pair of ends that are engaged with a tensioning mechanism. The tensioning mechanism applies a tensioning force to the ends of the brake band to tension the brake band against the brake member to inhibit rotation of the drive shaft and thus movement of the mobile storage unit when the input force is relieved.

Abstract: A mechanical safety braking device for use with a mobile storage unit forming a part of the mobile storage system. The device includes an actuating member disposed on a mobile storage unit that is operably connected to a braking mechanism engaged with a motive system for the mobile storage unit. When the actuating member is engaged, the mechanical connection between the actuating member and the braking mechanism causes the braking mechanism to slow and ultimately cease the operation of the motive system and consequent movement of the mobile storage unit.

Abstract: The present invention is a mechanical safety braking device for use with a mobile storage unit forming a part of the mobile storage system. The device includes an actuating member disposed on a mobile storage unit that is operably connected via a mechanical means to a braking mechanism engaged with a motive system for the mobile storage unit. When the actuating member is engaged, the mechanical connection between the actuating member and the braking mechanism causes the braking mechanism to slow and ultimately cease the operation of the motive means and consequent movement of the mobile storage unit.
