GB/T 26079-2025Beam-type lifting devices (English PDF)

Foreword

This document complies with the provisions of GB/T 1.1-2020 "Standardization Work Guidelines Part

1.Structure and Drafting Rules of Standardization Documents". Drafting. This document replaces GB/T 26079-2010 "Beam Lifting Equipment". Compared with GB/T 26079-2010, the main differences are structural adjustments and editorial changes. Aside from the changes, the main technical changes are as follows:

a) The requirements for critical load-bearing welds have been revised (see 7.2.2,

7.6.2.2 in the.2010 edition);

b) The inspection and acceptance rules for butt joint full penetration welds and other welds in box girder and single-web girder structures have been revised (see 7.2.3,.2010 edition). 7.6.2.3);

c) The requirement for stress relief in the beam structure has been increased (see 7.2.5);

d) The requirement for operating temperature has been removed (see

7.3.1.1 in the.2010 version);

e) The provisions for fatigue verification of beams have been revised (see 7.3.1.4,

7.5 in the.2010 version);

f) The technical requirements for pulleys have been revised (see 7.4,

7.10 in the.2010 edition);

g) Added relevant methods for static equilibrium testing (see 8.5,.2010 edition of 8.5);

h) The requirements for static load testing have been revised (see 8.6,.2010 version of 8.6). Please note that some content in this document may involve patents.

1 Scope

GB/T 26079-2025 is the Chinese national standard covering the spreader beam - the bar between the crane hook and the load that keeps the slings vertical, with its design against bending and buckling, its lifting points, its proof testing and its marking. Issued on 2 December 2025, it has been in force since 1 July 2026, replacing GB/T 26079-2010.

1.Uncoated steel Rust level and treatment level of the surface and the steel surface after complete removal of the original coating.

2.Coated steel Treatment level after partial removal of the original coating on the surface
