An overhead catalyst loading device eliminates the need for lower flanges of the overhead catalyst structural support frame or dedicated overhead trolley beams to prevent ash build up collecting on a selective catalytic reactor (SCR) reactor box and provides an advantageous electric hydraulic lifting mechanism suitable for integration into a SCR device. The overall width of the SCR device is reduced since the structural support frame in the SCR device fits in the gaps between catalyst blocks. The overhead electric hydraulic catalyst loading device also minimizes the chance of injury during catalyst block installation by using an electric hydraulic actuated lifting mechanism consisting of spacers and structural telescopic members which may comprise holes and pins for height adjustment to allow for loading and unloading catalyst blocks into and out of a SCR device. Methods of lifting and loading and unloading a catalyst block are also presented therein.

Electric hydraulic catalyst loading and unloading device and methods therefor

An improved roof or ceiling fitting for a monorail system, particularly useful in low seam coal mines. Rail suspension assemblies are each secured in a single counterbored roof hole and are adjustable vertically and laterally for alignment. A bolt is anchored in a hole and supports a collar-end of a crank-shaped suspension unit within the counterbore. A suspension-pin end offset from the collar axis extends below the roof to support a cleat for attachment to a rail. A roof plate is threaded on the collar and bears against the roof.
