3.12 (3.12~3.14 in the 2009 edition)

---Change the terms "slewing limiter," "telescopic limiter," and "trolley and crane travel limiter" to "slewing limiter," "telescopic limiter," and "trolley and crane travel limiter," respectively.

"Travel limiter" and "running stroke limiter" (see 3.14~3.16, 3.17~3.19 in the 2009 edition);

---The terms "event logger" and "data logger" and their definitions have been added (see 3.18 and 3.19);

---Changed the general requirements for rated lifting capacity limiters, load limiters, or indicators, and added requirements for design and installation, stating that they "should be able to..." the relevant requirements for "performing functional checks on its own circuitry and responses" are detailed in section 4.2 (see section 4.2 of the 2009 edition).

---The operating requirements for the rated lifting capacity indicator have been changed (see 4.4.1.2, 2009 version 4.4.1.2);

---The requirement for routine inspection of the rated lifting capacity indicator has been removed (see 4.4.3 in the 2009 edition);

---The requirements for inspection have been changed (see Chapter 5, Chapter 5 of the 2009 edition);

---The warning about paint scheme in the usage information has been removed (see 8.3, 2009 version 8.3).

Introduction

Crane limiters and indicators are core systems for the safe operation of cranes. GB/T 24810 "Crane Limiters and Indicators" is...

Important standards that specify the general requirements for crane limiters and indicators.

GB/T 24810 consists of five parts.

---Part 1: General Rules. The purpose is to regulate the general requirements for crane limiters and indicators.

---Part 2: Mobile Cranes. The purpose is to standardize the load, movement, performance, and environmental limits and specifications for mobile cranes.

Special requirements for the display.

---Part 3: Tower Cranes. The purpose is to specify the special requirements for limiters and indicators on tower cranes.

---Part 4: Boom Cranes. The purpose is to regulate the load, movement, performance, and environmental limits and indications for boom cranes.

Special requirements for the instrument.

---Part 5: Bridge and Gantry Cranes. The purpose is to standardize the load, motion, performance, and environmental aspects of bridge and gantry cranes.

Special requirements for limiters and indicators.

3 Terms and Definitions

The terms and definitions defined in ISO 4306-1, as well as the following terms and definitions, apply to this document.

Anti-colision device A device to prevent a crane or its components from colliding with a fixed lifting device or other crane when they are moving simultaneously in the same space.

Note. In some applications, the workspace limiter can function as a collision avoidance device.

Configuration

The combination and arrangement of structural components, counterweights, support components or outrigger positions, hook pulley block winding systems and similar components, and the basis for
