Overview
Insulation Overhead Crane
The insulation overhead crane is a specialized lifting device designed for environments with high-voltage currents or electric leakage risks. Its core function is to prevent electric current from being transmitted through the crane to the ground or operator by isolating conductive parts using insulation materials, ensuring safe operation in high-risk electrical conditions.
Key Features
Intro
-
Insulation Grades & Standards
-
Insulation Materials:
Key components such as hook assemblies, wire ropes, and pulleys use high-strength insulating materials like epoxy resin, nylon, or polyurethane. Insulation resistance ≥10 MΩ (tested with 500V megohmmeter).
-
Voltage Rating:
Customizable insulation levels from 1kV to 35kV to meet various application needs, such as 800V–1000V DC in electrolytic aluminum workshops.

Faqs
How can I choose right cranes?
We have 24-hour online customer service to provide you with professional consulting services and help you choose the right crane according to your working conditions.
Are your cranes customizable?
Yes, we support customization to meet specific lifting requirements. Factors such as lifting capacity, span length, lifting height, and control options can be tailored to suit your needs of the industry or application. Customization ensures optimal performance and efficiency.
I have low headroom in my workshop, is it possible to install a crane in it?
We have special products for low headroom workshop, our engineer can give the best design according to your dimensions.
What kind of package for Hoist or Cranes?
Hoists and Electricals packed in fumigation wooden box. Main beams covered by woven plastic cloth.
When the main girder is too long, how to delivery by container?
The main girder will be divided into different pieces, each part’s length is within 11.8m. When client receive the goods, just connect them with high strength bolt is okay.
How can you provide after-sale service?
This is a common concern for customers. We provide one-stop service, from delivery, installation to after-sales. We will have online customer service ready to solve your problems at any time, we also provide after-sales documentation support, such as operation manuals, maintenance manuals, etc. If the problem still not be solved, we can send our engineers to your site.
