introduction
Unifying and standardizing the terminology and commercial specifications of fixed concrete placing booms will help standardize the domestic fixed concrete placing boom market.
The revision of ISO 17740-1.2015 is conducive to exchanges with international peers and promotes domestic fixed
Concrete placing boom products are introduced to the world.
The unification of the terminology and commercial specifications of fixed concrete placing booms ensures the communication and cooperation between product manufacturers and users.
Smooth.
GB/T 44747 "Construction Machinery and Equipment - Fixed Concrete Placing Boom" is a standard for determining the fixed concrete placing boom.
The standardized specification is planned to consist of two parts.
--- Part 1.Terminology and commercial specifications. The purpose is to unify and standardize the terminology and commercial specifications of fixed concrete placing booms.
--- Part 2.Safety requirements. The purpose is to specify the structural and performance requirements of fixed concrete placing booms in terms of safety.
