Updated ASME BTH-1-2017 Design of Below-the-Hook Lifting Devices Available Now

by ITI Marketing March 27, 2017

The much anticipated ASME BTH-1-2017 Design of Below-the-Hook Lifting Devices standard has been revised. The revision supersedes the 2014 version of the standard, serving as a guide for designers, manufacturers, purchasers, and users of below-the-hook lifting devices.

BTH-1 addresses only design requirements, and is intended to be used in conjunction with ASME B30.20 Below-the-Hook Lifting Devices, which addresses safety requirements. The BTH-1 provides minimum design criteria requirements.

Many editorial changes, revisions, and corrections have been made to the ASME BTH-1-2017, including these few items:

Chapter 6: Magnet Lifting Design (added)
Definitions of applied load(s), dead load, load cycle, maximum stress, minimum stress, and rated load (added)
Definitions of equalizing sheave and running sheave (added)
Definitions of electrical power supply, electric motor, externally powered electromagnet, and master switch (added)
Definitions of shall and should and location where design factor is first used (revised)
Location where brake, control system, rectifier, and sensor(s) are first used (revised)
Table 3-2.2-1 Limiting Width-Thickness Ratios for Compression Elements (Updated)
