Frequently Asked Questions (FAQs)

What are the basic structural components of a Chinese small truck crane?

The basic structural components of a Chinese small truck crane include the rotation part, the chassis part, and the slewing support part. The rotation part is equipped with a lifting mechanism, luffing mechanism, and other devices, allowing for good maneuverability and quick transfer between duty stations. The chassis part typically uses a standard truck chassis, but for larger tonnage cranes, a special truck chassis is employed to improve the utilization ratio of the crane. The slewing support part, installed on the running part of the vehicle, supports the upper rotating part by transferring loads to the chassis through the supporting wheel, ensuring the stability and flexibility of the rotating part.

What are the key components of a gantry crane structure?

A gantry crane structure consists of several key components. The bridge or girder is the primary horizontal beam that spans the width of the crane and supports the hoist and the load. Gantry cranes can have either a single girder for lighter loads or a double girder for heavier capacities and longer spans. The legs are vertical supports that transfer the load to the ground or rails. The hoist is the lifting mechanism that moves along the girder, and the trolley carries the hoist and moves horizontally on the girder. Additionally, the crane running mechanism includes wheels or rollers driven by electric motors, and the runway is the set of tracks on which the crane travels.

How do tower cranes ensure stability and structural integrity?

Tower cranes ensure stability and structural integrity through several critical components. The mast sections form the vertical backbone of the crane, supporting the boom and counterweight. Fixing angles and fishing plates secure the various sections of the crane, ensuring structural integrity. Wall ties anchor the crane to the building, preventing it from toppling. These components work together to provide stability, strength, and safety, allowing the crane to operate effectively and securely.

What information is typically included on the nameplate of a crane in China?

The nameplate of a crane in China typically includes several important parameters. These include the Product License Code, which is required for the production of special equipment like cranes. The type code indicates the specific model of the crane. The rated lifting capacity is the maximum weight the crane can lift under normal working conditions, measured in tons or kilograms. Other information includes the lifting speed, which is the vertical displacement speed of the rated load, and the crane travel speed. Additionally, details such as the span, main lifting height, auxiliary lifting height, and product number are also provided. For explosion-proof cranes, the nameplate includes symbols indicating the explosion protection capabilities.
