Dangers of extending Leads
Crane lifting capacity is based on many factors including the length of the boom.
Extending the boom reduces lifting capacity.
When extending the leads above the boom, please have all lifting calculations reviewed by a qualified engineer and the crane manufacturer.
Do not read crane charts based on crane boom and lift from this point.
Crane load charts calculate from here.
Distance from crane center changes when adding fixed leads and spotting back.
