Rack Outriggers With Braking Interlock System

Racks for ITE equipment can become extremely heavy and unstable when fully loaded. When these racks are transported or relocated within a building, they are usually rolled on their casters. The grounds for transporting the rack may not be level and may include ramps, floor obstructions, or depressions. The stability of these systems must be maintained while the rack is moved in order to provide for the safety of the people moving the rack. Racks must never be allowed to tip over during transport, as people could be critically injured and equipment could be damaged. Safety during transport must be maintained at all times of transport, during the initial installation, during use, and during decommissioning at the end of product life.

    To reduce the risk of tipping over, racks can be shipped partially populated, in order to lower the center of gravity. However, these racks must be re-populated in the field, increasing the overall cost of shipping and the service time required to repopulate and test.

    The stability of racks during transport can also be enhanced by the use of outriggers. Outriggers are devices with casters that are attached to the rack to effectively increase the wheel base length or width and, subsequently, increase the stability of the rack. The problem with some outriggers is they need to be installed before relocation and removed once the rack reaches its final destination. Safety instructions always warn the customer to restore the rack to its original shipped configuration or install outriggers if they were originally shipped with the rack. But under foreseeable misuse, the outriggers may not be installed in the rush to move the rack and, therefore, the risk of a tip-over accident is increased over the life of the product.

    This invention adds a braking system to the casters which is actuated when the outriggers are removed. An interlock between the brakes and the outriggers is added to disengage the brakes when the outriggers are present. This system allows the rack to be transported only when the outriggers are installed. This improves the safety during transport,...
