摘要： A support column cylinder assembly is provided for use with a support column assembly having upper and lower support tubes and a slidable clamp component for frictionally clamping the upper support tube relative to the lower support tube. Some embodiments of support column cylinder assembly comprise a first bearing member, a second bearing member, and at least two hydraulic cylinders operatively connected between the first and second bearing members, the at least two hydraulic cylinders being operative to apply a force to the second bearing member relative to the first bearing member. The second bearing member is adapted to be positioned against a clamp component of a support column for applying a force to the support column clamp component relative to the first bearing member.

摘要： A longitudinally yieldable support for underground roof support includes a first support section with a first elongate outer shell partially filled with a solid compressible filler material and a second support section at least partially filled with a second solid compressible filler material. The second support section is at least partially disposed within the first elongate outer shell and is telescopically extendable relative thereto. A bladder is interposed between the first and second support sections that is fillable in situ to cause extension of the second support section relative to the first support section when filled under pressure with a filler material.

摘要： A longitudinally yieldable support for underground roof support includes a first support section with a first elongate outer shell filled with a solid compressible filler material and a second support section filled with a second solid compressible filler material with a second elongate outer shell extending above the first elongate outer shell. The second support section has density that is greater than a density of the first solid compressible filler material. A pair of attachment members are coupled to the second elongate outer shell and are configured for lifting the second elongate outer shell relative to the first elongate outer shell and for securing the second elongate outer shell relative to the first elongate outer shell once lifted.
