What is a crane?

A crane is a mechanical device used to move heavy objects vertically or horizontally, and is widely used in construction, manufacturing, logistics, and ports. Its main function is to lift, carry and position heavy objects through mechanical or hydraulic systems. This article will combine the hot topics and hot content on the Internet in the past 10 days to introduce in detail the classification, working principles and application scenarios of cranes.

1. Classification of cranes

What is a crane?

According to different structures and working methods, cranes can be divided into the following categories:

typeFeaturesApplication scenarios
Bridge craneAcross the workshop or warehouse, moving on railsfactory, warehouse
tower craneFixed or mobile, height adjustablebuilding construction
truck craneInstalled on the car chassis, highly maneuverableLogistics, rescue
Gantry craneDoor-shaped structure, suitable for open spacesport, wharf

2. Working principle of crane

The working principle of the crane is mainly based on mechanics and mechanical transmission. The following is its core workflow:

1.Power system: Cranes are typically powered by electric motors, internal combustion engines, or hydraulic systems.

2.Transmission system: Transmit power to the lifting mechanism through gears, chains or wire ropes.

3.control system: The operator regulates the operation of the crane via the console or remote control.

4.safety device: Including limiter, overload protection, etc. to ensure safe operation.

3. Hot topics and crane-related hot topics in the past 10 days
