Construction Cranes In Seattle
According to a January 2019 report by surveyors from Rider Levett Bucknall who count cranes in major cities every six months, Seattle has 59 cranes (including the one that feel). That number is down from 65 cranes last summer in July of 2018.
Crane Accident Statistics
From 2011 to 2015, the Census of Fatal Occupational Injuries (CFOI) reported 220 total crane-related deaths, an average of 44 per year over this 5-year period. Men accounted for 217 of the 220 fatal injuries involving cranes.
According to an article appearing in the September 2009 issue of International Cranes Magazine, between 2000 and 2010 26% of serious or fatal crane accidents happen during the erection or dismantling of the crane. The primary cause for these failures is the failure of workers to properly follow manufacturer instructions. The article stated that only 10% of crane accidents are due to weather conditions. And over 25% of deaths and injuries were suffered by non-construction personnel.
According to the National Commission for the Certification of Crane Operators (NCCCO), 323 construction workers died in crane accidents between 1992 and 2006. Of those, 32 percent were caused by electrocution due to contact with overhead power lines, 21 percent were due to cranes collapsing, and 18 percent were caused by a crane boom striking a construction worker.

Crane Construction 101
Cranes can be either owned or leased. One of the biggest hazards is cranes operated by unqualified crane operators on multi-employer worksites. To minimize the cost of crane use, construction companies may rent a crane with an operator provided by the rental company, rent only the equipment because the general contractor already has an operator on staff, or they may hire a short-term employee or a contractor separately to operate the crane.
Most construction companies rent tower cranes from a crane vendor. The crane vendor ships the crane to the site, assembles it; charges a monthly fee while the crane is on the site; and handles the dismantling and removal of the crane.
