Cranes from Texas Truck Racks are tools for lifting sewer machines, water heaters and more. They increase productivity, reduce the risk of back injuries, and turn a two-man job into a one-man job. Add to that a quick return on investment and it is a win-win for the plumber and the business owner. Upper and lower mounting brackets reduce the strain on the floor of the vehicle over floor-mount cranes. Units consume very little valuable floor space. A 3,000-pound-rated winch with mechanical braking is included and holds the load even with power loss. The lift capacity is conservatively rated at 500 pounds. 877-900-0057; www.texastruckracks.com.
