The lifters mounted on the equipment rack are controlled by a remote control passing signals through a power supply/relay control box that are connected to the rack mounted lifters. Through the attachment and activation of rack mounted lifters, the assembly may raise and lower fully loaded equipment racks in a vertical direction to assist in the maintenance and relocation of equipment racks or other data center equipment. ## Claims ### Claim 1 An apparatus for moving datacenter equipment in a vertical orientation, comprising: a plurality of equipment lifting components, each of them mountable to an item of equipment; a power supply; a relay control in electrical communication with each of the plurality of equipment lifting components; and a remote control in electrical communication with the relay control and configured to control the action of each of the plurality of equipment lifting components. ### Claim 2 (depends on 1) The apparatus of claim 1, where each of the equipment lifting components comprise an electro-mechanical or hydraulic actuator in association with an electric activation motor, an external cylinder and an internal cylinder where the internal cylinder extends from and retracts into the external cylinder when the electric activation motor activates the electro-mechanical or hydraulic actuator. ### Claim 3 (depends on 1) The apparatus of claim 1, where the power supply is separate from the equipment lifting components. ### Claim 4 (depends on 1) The apparatus of claim 1, where the remote control comprises at least one activation switch for each equipment lifting component and an activation switch for activating all equipment lifting components simultaneously. ### Claim 5 (depends on 4) The apparatus of claim 4, where each activation switch comprises an internal lighting element where said lighting element activates when the activation switch is electrically connected to the power supply. ### Claim 6 (depends on 1) The apparatus of claim 1, where the power supply and relay control are co-located within a single component. ### Claim 7 (depends on 1) The apparatus of claim 1, where the remote control is electrically connected to the power supply/relay control and the power supply/relay control is electrically connected to the activation motor associated with each equipment lifting component. ### Claim 8 (depends on 1) The apparatus of claim 1, where each equipment lifting component comprises a load-bearing element. ### Claim 9 (depends on 8) The apparatus of claim 8, where the equipment lifting component load bearing elements are connected to an equipment item or equipment rack in a configuration sufficient to support the weight of the equipment item or equipment rack during lifting actions. ### Claim 10 (depends on 1) The apparatus of claim 1, where the equipment lifting components are fastened to the equipment item or equipment rack through the load-bearing elements associated with each equipment lifting component, the equipment lifting components are electrically connected to activation switches associated with the remote control and then to the power supply/relay control, where lighting elements associated with activation switches on said remote control are active when electrical connectivity is established, where the equipment lifting components are active to raise and lower an equipment item or equipment rack when said activation switches are activated by an operator. ### Claim 11 A system for moving datacenter equipment in a vertical orientation, comprising: a plurality of equipment lifting components, each of them mountable to an item of equipment; a power supply; a relay control in electrical communication with each of the plurality of equipment lifting components; and a remote control in electrical communication with the relay control and configured to control the action of each of the plurality of equipment lifting components. ### Claim 12 (depends on 11) The system of claim 11, where each of the equipment lifting components comprise an electro-mechanical or hydraulic actuator in association with an electric activation motor, an external cylinder and an internal cylinder where the internal cylinder extends from and retracts into the external cylinder when the electric activation motor activates the electro-mechanical or hydraulic actuator. ### Claim 13 (depends on 11) The system of claim 11, where the power supply is separate from the equipment lifting components. ### Claim 14 (depends on 11) The system of claim 11, where the remote control comprises at least one activation switch for each equipment lifting component and an activation switch for activating all equipment lifting components simultaneously. ### Claim 15 (depends on 14) The system of claim 14, where each activation switch comprises an internal lighting element where said lighting element activates when the activation switch is electrically connected to the power supply. ### Claim 16 (depends on 11) The system of claim 11, where the power supply and relay control are co-located within a single component. ### Claim 17 (depends on 11) The system of claim 11, where the remote control is electrically connected to the power supply/relay control and the power supply/relay control is electrically connected to the activation motor associated with each equipment lifting component. ### Claim 18 (depends on 11) The system of claim 11, where each equipment lifting component comprises a load-bearing element. ### Claim 19 (depends on 18) The system of claim 18, where the equipment lifting component load bearing elements are connected to an equipment item or equipment rack in a configuration sufficient to support the weight of the equipment item or equipment rack during lifting actions. ### Claim 20 (depends on 11) The system of claim 11, where the equipment lifting components are fastened to the equipment item or equipment rack through the load-bearing elements associated with each equipment lifting component, the equipment lifting components are electrically connected to activation switches associated with the remote control and then to the power supply/relay control, where lighting elements associated with activation switches on said remote control are active when electrical connectivity is established, where the equipment lifting components are active to raise and lower an equipment item or equipment rack when said activation switches are activated by an operator.
