Internal tank liners are less expensive options for satisfying secondary containment requirements in many states. For installation purposes, a crane is needed for each install to place the PVC liner in the tank. Many types of cranes exist for transferring significant weight loads to varying heights. For installing PVC liners, a crane with a smaller capacity and reach can be used based on the installation details.
Crane Requirements
Heartland Tank Services, Inc. normally recommends a crane that has a weight capacity of 5,000 pounds or more and a boom lift minimum between 40 and 45 feet. Above ground storage tank liners need to be lifted by the crane to the machine hatch in the tank roof. With an average secondary containment liner weighing between 2,500 and 4,800 pounds and a tank roof being between 24 and 32 feet, a truck crane can normally handle the job.
The machine hatch in the roof of a storage tank does serve to provide extra light and ventilation for a tank being serviced, but its main purpose is to accommodate the installation of an internal tank liner. The weight and size of the liner makes it prohibitive to shuttle it through the shell manway.
Timing Important
The customer is responsible for arranging for the rental of the crane. Timing the arrival of the crane is crucial to keeping the install on time. While the crane is only used for about an hour or two, its absence at the point when the liner is ready to be lifted will bring the installation to a dead halt until the crane is available.
A crane can normally be obtained from a local equipment dealer or rental facility. Finding a crane rental that is close to the site location is helpful as that limits the travel time of the crane, which can translate into a lower cost of the rental. A good liner installation company will inform you at least a week before the install as to the time of the day that the crane will be used. This will minimize your cost in how long the crane will need to be on site.
