Abstract: A hard drive tray device applied in a server is provided. The server includes a housing. The hard drive tray device includes a rail member and a tray. The rail member is disposed at the inner wall of the housing. The tray is slidably engaged with the rail member so as to slide between an expanded position and a closed position relative to the housing. The tray includes a base for carrying two storage devices. The base has a hollow portion. The storage devices are respectively located at two sides of the hollow portion. When the tray slides to the expanded position, one of the storage devices and at least a part of the hollow portion are located outside the housing.

Abstract: A server includes a casing, a bottom plate, a first hard disk module, a second hard disk module, and a lifting device. The bottom plate is disposed in the casing and configured to be sliding relative to the casing. The first hard disk module is movably disposed on the bottom plate. The first hard disk module includes a track. The second hard disk module is fixed on the bottom plate and disposed behind the first hard disk module. The lifting device moves up the first hard disk module when the bottom plate is pulled out of the casing, and the lifting device moves down the first hard disk module when the bottom plate is pushed into the casing. A drawer lifting device is also disclosed.

Abstract: A support pole for raising and lowering a supported object between a lower position and an elevated position is disclosed. The support pole includes an elongate pole and a carriage mounted for translational movement up and down the pole. Carriage locks at the top of the pole engage the carriage in the elevated position to prevent vibration of the supported object, and a stabilizer frame within the channel minimizes vibration during carriage transport.

Abstract: A support pole for raising and lowering a supported object between a lower position and an elevated position is disclosed. The support pole includes an elongate pole having a top, a bottom, and a channel extending at least partly between the top and bottom. A threaded rod is rotationally mounted within the channel, and is connected to a detachable coupling for engaging a drive tool to rotationally drive the threaded rod. A carriage engages the threaded rod, such that rotation of the rod imparts translational movement upon the carriage through the channel. The carriage includes a mounting bracket for attachment of the supported object thereto. A cable connecting the supported object and an external device or power source has a detachable coupling, and is carried along a pulley at the top of the elongate pole when the carriage is raised and lowered.
