___________________________________________________Operation SIDE SLEW (LIFT AND SLEW) purpose The side slew device provides a means of moving the entire BTP
horizontally in a lateral direction across the width of the entryway so that proper belt alignment can be maintained. The lift jack portion of the side slew device provides a means of vertically leveling the BTP in relation to the belt line while stabilizing the BTP frame within the entryway during normal mining operations. The side slew lift jacks can also raise the BTP completely off of the mine floor so that work can be performed on the BTP.
construction The side slew attachment brackets are constructed from welded

structural grade steel with high strength bolt on cylinder retention blocks. The lift portion of the side slew device is operated by two independently functioning trunion mounted hydraulic cylinders which connect to horizontal slide blocks that are housed within the side shift skid plate. Two vertical steel slide plates are pinned to the slide blocks to absorb any side loads. The side shift skid plate is constructed from welded structural grade steel with a high wear steel bottom plate. The side-shift portion of the side slew device is operated by two clevis mounted cylinders that function, by one pushing and one pulling at all times. All pins are made from high-tensile steel rods.
maintenance Visually inspect all joints to ensure that pins are properly in place by
one of the following: bolts, clip pins or roll pins. This depends on the design. Ensure that the hydraulic cylinder and hoses are not leaking or damaged and that the cylinder rods are not bent. Visually inspect the bolt on side-shift cylinder cover plates for worn or missing components. Keep debris away from the side-shift cylinders and hoses. Replace or repair any missing or damaged components as required. Manually grease all sliding connect points between the vertical slide plates and the mounting brackets and also between the slide block and the side shift skid plate.
IMPORTANT
Certain designs may provide grease fittings within the head of each pin. These fittings should be greased monthly.
