摘要： PURPOSE:To shorten the total length of a clamp and to enable using of the steel tower and metal wheel with a small radius of curvature by giving the tensile stress of a wire to a thread part and by assembling each member in an overlapped manner. CONSTITUTION:One end of a steel clamp 1 is formed into a clevis type anchor part, and an axial blind hole is made at the other end thereof and the innermost part of said blind hole is used as a threaded hole 1a. A steel fittings 2 is a small cylindrical body fittable into said steel clamp blind hold, and one end of said fittings 2 is formed into a threaded part to be screwed into said threaded hole 1a and a blind hole 2a is made at the other end thereof. An aluminum sleeve 4 is inserted into the steel clamp blind hole so as to internally make contact with said hole. An aluminum cable steel reinforced 3 is inserted into the steel clamp blind hole via said aluminum sleeve 4, the end face of said aluminum-steel cable 3 is step-stripped, and the exposed steel core wire is inserted into and contact-bonded to the blind hole 2a.

摘要： PURPOSE:To reciprocate a steel tower pulley freely, by forming a weight member into N-type, whose central section is a leaf with suitable flexibility, and by providing a dent to allow this leaf to fit in on the undersurface of a connector. CONSTITUTION:Each member of a weight row 6 is a connection of central sections of right and left links with leaves 7, in which the right and left links are pivotably attached separately with pins. Each member of connector rows 3, 4 and 5 consists of bar segments and pivotably attached one after another at the same pitch as do the members of the weight row 6. Each member is equipped with a dent 8 to allow a leaf 7 to be fitted in. The connector rows 3, 4 and 5 are thereby fitted into a surface of a weight member in the outward work process and in the homeward work process into the other surface, so that when both are integrated they can get over the pulley without ado.
