Specific requirements for the environmental site

 

Before the operation, it is necessary to investigate and explore the environment of the site, and it is also necessary to carry out basic layout and improvement of the site, so as to ensure the smooth progress of the lifting operation.

 

The construction site should be leveled to achieve "four connections and one leveling", and the construction water, electricity and gas should meet the use conditions;
 

In addition, in case of dark or foggy weather, reliable lighting/eye-catching lights, communication and fire-fighting facilities should be provided on site, and the fire-fighting exits should be unblocked;
 

The construction site where the equipment is installed should be reliably isolated and isolated from other systems under construction;
 

There are storage places for parts, tools and construction materials, etc., and there should be corresponding protective measures such as windproof, rainproof, antifreeze, etc., and parts that pass the inspection should be put into storage in time for proper storage if they cannot be installed temporarily;
 

The main body of the civil works related to the installation of lifting equipment is completed, and the lightning protection and grounding are perfect.
