How much does a crane rental cost? The cost of renting a crane will depend on the duration of the rental, where you rent it from, if an operator is needed, the type of crane and the geographical location. Based on these factors, most construction cranes can be rented for $100 to $1,000 per day, $1,000 to $3,000 per week or up to $6,000+ per month. The prices may go down or up, depending on the type of crane and the rental company. If you were to need an operator and the crane, then the rental company will more than likely charge by the hour. Depending on the crane setup, these fees can range anywhere from $100 for a 14-ton hydraulic crane to as much as $350 per hour for a 100-ton hydraulic truck crane. These rental companies, when they do provide an operator, will usually ask for a three to five-hour commitment.
