Duty Class & Mechanisms
An important reference for classifying crane mechanisms and defining requirements based on operating intensity and duty cycle.
ACG ENGINEERING
STANDARDS & QUALITY
ENGINEERING COMPLIANCE
Standards are part of engineering.
At ACG, a standard is not a decorative badge added at the end of a project; from duty-class selection and engineering through manufacturing, control and testing, standards are embedded in technical decisions and project documentation.

STANDARDS FRAMEWORK
There is no single standard for every project.
The technical framework of each project is selected according to equipment type, duty class, capacity, operating conditions and contractual requirements. ACG uses multiple families of engineering standards to define design and verification requirements.
Industrial Design & Engineering
A family of technical references used for engineering design, mechanical components, manufacturing and industrial equipment requirements.
International Framework
International references for classification, design, quality, safety and documentation across industrial disciplines.
European Requirements
European standards related to machinery, lifting equipment, safety, performance and product requirements.
Electrical & Control
Technical frameworks for electrical equipment, control systems, panels and machinery electrical infrastructure.
Crane Engineering
A specialized crane-industry reference for classification and engineering requirements of industrial crane systems.
APPLICATION MATRIX
Where do standards enter the project?
Each standards family has a different role. Mechanism design, structure, electrical systems, lifting equipment and testing do not necessarily follow one reference; the technical framework must be selected for the specific equipment and project.
Engineering Area
Reference Frameworks
Project Application
01
Crane Design
FEM
ISO
DIN
CMAA
Duty class, mechanisms, load cases and crane-system design requirements.
02
Structure & Mechanical Components
DIN
EN
ISO
Component design, manufacturing, tolerances and verification of project mechanical specifications.
03
Electrical & Control
IEC
EN
EN 60204-32
Electrical equipment, control panels, machine control and safety requirements for hoisting systems.
04
Lifting Equipment
EN 13155
FEM
DIN
ISO
Design and verification of below-the-hook equipment and specialized load-handling solutions.
05
Inspection & Testing
PROJECT SPEC
EQUIPMENT STD.
Definition of inspection points, functional tests, load tests and project acceptance criteria.
06
Technical Documentation
ISO
PROJECT DOC.
Drawings, inspection documents, test results and equipment handover documentation.
ENGINEERING LIFECYCLE
Standards enter the process from the start of the project.
The technical framework is not limited to final inspection. Project requirements must be transferred from the beginning into design, manufacturing, inspection and documentation decisions.
Project Requirements
Capacity, span and duty class, environment and client requirements.
Standard Selection
Selection of design references and project verification criteria.
Engineering
Converting requirements into calculations, drawings and technical specifications.
Manufacturing
Manufacturing in accordance with approved engineering documents.
Inspection & Testing
Verification of inspection points and equipment acceptance criteria.
Documentation
Recording documents, inspection results and handover technical information.
VERIFICATION & QUALITY
A standard without verification is only a reference on paper.
Technical compliance is meaningful when design requirements remain traceable through manufacturing and quality control. Inspection and test points are defined according to equipment type and project specifications.

Material Control
Material & Component Control
Verification of required component and material specifications against project technical requirements.
Dimensional Inspection
Dimensional Inspection
Verification of dimensions, geometry and critical points at defined manufacturing stages.
Welding Control
Welding Process Control
Verification of structural fabrication requirements against project specifications and documents.
Assembly Review
Assembly Review
Review of component integration and equipment preparation before functional testing.
Functional Test
Functional Test
Verification of mechanisms and electrical systems according to the project scope.
Load Test
Load Test
Execution of required tests according to equipment type and project acceptance criteria.
Documentation
Records & Documentation
Retention of technical documents and inspection results for handover and operation.
PROJECT-SPECIFIC COMPLIANCE
The final standard framework starts with the project itself.
Standards are not selected by product name alone. Equipment type, capacity, duty class, operating environment, safety requirements, client specifications and project documents all influence the technical framework.

ACG ENGINEERING NOTE
The standards framework of each project is determined after reviewing technical specifications
and actual operating requirements.
CERTIFICATES & DOCUMENTS
Quality and Standards Documentation.
Selected documents, certificates and records related to the quality system and frameworks used by ACG are presented in this section. The validity and scope of each document must be verified from the document itself.

Displaying a standard or document on this page does not mean it automatically applies to every product or project; the scope of compliance for each project is defined by its technical specifications and project documentation and must be verified accordingly.
ENGINEERING REVIEW
Define the project standards before manufacturing begins.
For review of duty class, design standards, electrical requirements, testing or project documentation, send the initial specifications to the ACG engineering team.
