Quenching Crane

Product Name: Quenching Crane

Lifting Weight: 5t ~ 50t

Span: 10.5m ~ 31.5m

Working Duty: A5, A6, A7

Quenching crane is a special lifting equipment used for the metal heat treatment vertical quenching process, lift large parts or slender parts quickly immersed in quenching liquid. Quenching cranes are mainly used for quenching process with cooling medium such as salt water, water and mineral oil.

 

Quenching Crane

According to the quenching process requirements, hot work pieces need to quickly immersed in the quenching pool, in order to ensure uniform upper and lower metallographic structure of the workpiece, and to avoid the oil burning of oil surface burning. The most notable feature of quenching crane is the lifting mechanism has a rapid decline, accurate positioning and brake.

Weihua quenching cranes are design for vertical well quenching process, with rapid descent and emergency release function in accident.

320t Ladle Crane

Product Name: 320t Ladle Crane for Metallurgy

Structure: 4 girders and 6 rails

Lifting Capacity: 320t

Application: Metallurgical plant

This ladle crane is the largest metallurgical ladle crane ever made in Henan Province, China. During manufacture and installation, Weihua have carried out many test which lay the foundation for manufacturing this 320t ladle crane with more technology and complex structure.

320t Ladle Crane

Main structure of this crane is designed with 4 girders and 6 rails. The features of this crane: integral processing technology and secondary assembly technology. For the first time assembly, the welding components sizes are fixed and processed by flat position welding to ensure high quality of welding seams; and the secondary assembly is for releasing welding stress before the integral processing of the bridge to ensure the stability and accuracy of product process precision. The two times assembly technologies are great help to ensure the precision of gauge, diagonal and span, as well as users' site installation.
