Introduction

GB/T 24817 "The layout and characteristics of crane control devices" is to standardize the layout and requirements of crane control devices in my country

And the standard of movement direction aims to unify the layout and movement direction of crane control devices in our country, and keep it consistent with the international. By five

Partial composition.

---Part 1.General Provisions. The purpose is to specify the general layout and general requirements of crane control devices.

---Part 2.Mobile cranes. The purpose is to specify the layout and main characteristics of the mobile crane control device.

---Part 3.Tower crane. The purpose is to specify the layout and main characteristics of the tower crane control device.

---Part 4.Boom crane. The purpose is to specify the layout and main characteristics of the jib crane control device.

---Part 5.Bridge and gantry cranes. The purpose is to specify the layout and main

characteristic.

Operators of mobile cranes often need to operate cranes of different models or different manufacturers. This document specifies the basic crane control

The arrangement and action direction of the control device to reduce the operator's confusion and misoperation in emergency situations.

The layout and characteristics of crane control device

Part 2.mobile crane

1 Scope

This document specifies the layout, requirements and requirements of control devices used for mobile crane slewing, load lifting, boom luffing and telescoping.

The direction of action. Involving the basic layout and requirements of the two-way handle (two-way control device) and the cross shaft handle (multi-directional control device), and

ISO 7752-1 is used together.

This document applies to all mobile cranes defined in ISO 4306-2.
