Abstract
A method of assembling a hook block for a crane includes: providing a sheave housing containing a plurality of sheaves with a pivotal connection link secured to the top of the sheave housing, the sheave housing including extended portions each with a hole therethrough and a housing frame positioned below the plurality of sheaves, the housing frame having a locking surface; placing a cross beam on its side, the cross beam having stabilizing feet resting on the ground; positioning the extended portions of the sheave housing within a plurality of brackets of the cross beam, each bracket with a hole therethrough; aligning the holes of the extended portions of the sheave housing with the holes of the brackets; inserting a shaft through the aligned holes; securing a cap to an end of the shaft to resist lateral movement relative to the holes; and inserting a locking bar between the locking surface of the housing frame and a surface of a bracket of the cross beam, to resist relative movement between the sheave housing and the cross beam during further assembly.
