Cranes - Control layout and characteristics - Part 2: Basic arrangement and requirements for mobile cranes

This document establishes the arrangement, requirements and direction of movement of the basic controls for slewing, load lifting and lowering, and boom luffing and telescoping, on mobile cranes as defined in ISO 4306-2. It deals with bi-directional controls and the basic arrangement and requirements for cross-shift levers (multi-directional controls). It is intended to be used in conjunction with ISO 7752-1.

Overview

ISO 7752-2:2025 - "Cranes - Control layout and characteristics - Part 2: Basic arrangement and requirements for mobile cranes" specifies the basic control arrangement, movement directions and functional requirements for controls on mobile cranes (as defined in ISO 4306-2). Published as the third edition, it updates control layouts to include telescoping and luffing fly jibs and complements ISO 7752-1 (general principles). The standard aims to reduce operator confusion and improve safety and interoperability when operators move between different mobile crane models.

Key topics and technical requirements

• Control arrangement and direction of movement: Defines the location and directional movement for primary crane controls such as slewing, hoisting (lifting/lowering), boom luffing and telescoping. (Examples from the standard: pushing the slewing lever forward slews towards the boom; pulling hoisting levers back lifts the load.)
• Bi-directional and cross-shift (multi-directional) controls: Covers both two-direction levers and multi-axis cross-shift levers for cranes with fixed-length and telescoping booms, including selection-switch behavior.
• Ergonomics and accessibility: Controls must be within easy reach of the operator at the control station and designed to minimize fatigue, consistent with ISO 7752-1.
• Control safety features:
  • Neutral return: levers and pedals must return to neutral automatically when released.
  • Preventing duplicate assignments: means to ensure the same function is not available on multiple levers simultaneously.
  • Indicators for multi-function selectors and requirements for illumination or cabin lighting for night visibility.
• Winch convention: Hoisting 1 and Hoisting 2 denote primary and secondary winch movements; the primary hoisting control should be on the right-hand side.
• Remote control stations and optional arrangements: Includes provisions for remote control stations and alternative layouts (e.g., foot-pedal luffing arrangements).

Applications and practical value

• Ensures consistent control layout across mobile crane models to reduce human error during operation and in emergencies.
• Useful for manufacturers designing operator cabins, control consoles, and remote-control interfaces to meet international expectations for ergonomics and safety.
• Guides fleet managers, safety engineers and training organizations to standardize operator instruction, reduce transition risks when crews move between crane types, and support compliance and procurement decisions.

Who should use this standard

• Mobile crane manufacturers and OEM engineers
• Cab/control-system designers and integrators
• Safety managers, inspection authorities and certification bodies
• Crane operators, trainers and fleet procurement teams

Introduction
Mobile crane operators frequently transfer from one crane to another of different model or manufacturer.
This document establishes a consistent arrangement and movement for the basic controls used during the
crane-operating cycle, to reduce operator confusion or incorrect control in an emergency. Some cranes may
not be equipped with all functions shown in the figures of this document.

4 General requirements
The basic control arrangement of a mobile crane and the direction of movement of the controls shall not
differ from those specified in Clause 5 through Clause 8, to avoid the operator's confusion and physical
interference when operating different cranes. Some cranes may not be equipped with all functions shown.
Other arrangements for control devices may be chosen due to the nature and work of the machine, provided
the same directions of movement of this document are followed.
a) The basic controls used during the crane operating cycle (see Figures 1 to 7) shall be located within
easy reach of the operator while he/she is at his station.
