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

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)
