The ground must be level to within the crane manufacturer’s specifications and able to resist the forces imposed by the crane and load weights. Contact with overhead power lines continues to be a leading cause of death involving cranes.Consider using blocking/mats under all crane setups to help distribute the crane and load weights to a larger surface area.Are there any excavations, underground structures or utilities nearby that could affect the stability of the ground?
