The CRSI Design Handbook has been the reference book for cast-in-place reinforced concrete design since 1952. The 10th edition provides the necessary information needed for common reinforced concrete structural members such as columns, beams, footings, pile caps, retaining walls, and...
This SAE Standard covers minimum dimensional relationship for sheaves, drums, and wire rope for mobile, construction type lift cranes.
Sheave diameter not less than 15 times rope diameter. Design based on minimum breaking load or round strand equal lay 6 x 24 to 6 x 41 wire rope with independent wire rope core. Materials, heat treatment, head fittings, bedset, sheaves, proof load, examination, marking,...
Rope speed up to 100 ft/min; sheave diameter up to 12 in (300 mm). Design based on breaking load of ropes to BS 302 and BS 621 in the 6 x 37 group 100/110 tonf/in2 tensile strength. Materials and heat treatment, block shell, head fittings, becket, axle pins, sheaves,...
This document specifies the design loads and the design procedures for the structural design of stages and components of stages. The loads specified in this document are not applicable for the design of stage ropes or sheaves. Rope sizes are determined in...
This International Standard specifies the minimum practical design factors, Zp, for the various classifications of mechanism, rope types, rope duties and types of spooling and demonstrates how these are used in the determination of the minimum breaking force of the wire rope. It specifies...
Nomenclature; illustrations of form of rigs with typical head fitting of blocks; estimates of rope tensions; typical load diagrams; union purchase rig; estimating loading on various components; safe working loads of slewing guys for swinging derricks; single sheave block safe working loads;...
This document specifies the loads, the load combinations and the design procedures for the design of the steel and aluminium alloy structural members of conveyances used for the transport of personnel, materials, equipment and rock in vertical and decline shafts. The conveyances...
COVERAGE This specification covers dimensional and marking requirements on V-belts and V-belt sheaves of both the narrow multiple and classical multiple type. This specification also includes recommended practices for: • Design of V-belt drives. • Care and use of V-belts • Measuring...
