A fuel tank mounting system for movable machine is disclosed. The mounting system may include a fuel tank connected to a frame of the movable machine in such a manner as to allow vertical motion of the tank relative to the frame. The fuel tank may be mounted to the frame using a spring and/or a shock absorber. The fuel tank may be a cryogenic fuel tank for storage of liquid natural gas. The shock absorbers may be tunable so that the level of dampening provided by the shock absorber is tailored to the type of machine and the specific mode of operation of the machine.

1. A fuel tank mounting system for a movable machine, comprising: a tank; anda movable mounting apparatus connecting the tank to a frame of the movable machine, the movable mounting apparatus enabling vertical motion of the tank relative to the frame, the movable mounting apparatus including a sprin
1. A fuel tank mounting system for a movable machine, comprising: a tank; anda movable mounting apparatus connecting the tank to a frame of the movable machine, the movable mounting apparatus enabling vertical motion of the tank relative to the frame, the movable mounting apparatus including a spring and shock absorber, the shock absorber including tunable hydraulic dampening, the shock absorber including a stationary mode of operation being active when the movable machine is being loaded and a moving mode of operation being active when the movable machine is in motion, the shock absorber exhibiting a first amount of dampening in the stationary mode of operation and a second amount of dampening in the moving mode of operation, the second amount of dampening being greater than the first amount of dampening. 2. The fuel tank mounting system of claim 1, wherein the movable mounting apparatus includes a processor. 3. The fuel tank mounting system of claim 2, wherein the tank is a liquid natural gas tank which includes an inner cryogenic tank and an outer tank. 4. The fuel tank mounting system of claim 2, wherein the movable mounting apparatus includes a sensor in communication with the processor. 5. The fuel tank mounting system of claim 1, wherein the shock absorber includes a cylinder and a piston slidably disposed in the cylinder. 6. A movable machine, comprising: a chassis;an engine mounted on the chassis;a plurality of wheels supporting the chassis;a fuel tank supported by the chassis;a spring interconnecting the fuel tank and the chassis; anda shock absorber interconnecting the fuel tank and the chassis, the shock absorber including tunable hydraulic dampening, the shock absorber including stationary mode of operation being active when the movable machine is being loaded and a moving mode of operation being active when the movable machine is in motion, the shock absorber exhibiting a first amount of dampening in the stationary mode of operation and a second amount of dampening in the moving mode of operation, the second amount of dampening being greater than the first amount of dampening. 7. The movable machine of claim 6, wherein the fuel tank stores liquid natural gas. 8. The movable machine of claim 6, wherein the fuel tank includes an inner cryogenic tank, an outer tank and insulation therebetween. 9. The movable machine of claim 6, wherein the movable machine is a truck. 10. The movable machine of claim 9, wherein the movable machine is a dump truck. 11. The movable machine of claim 6, wherein the shock absorber includes a cylinder and piston slidably disposed in the cylinder. 12. The movable machine of claim 6, further including a processor and a sensor in communication with the shock absorber. 13. A method of mounting a fuel tank to a movable machine, comprising: providing a frame of the movable machine;connecting the tank to the frame in a manner as to allow vertical movement of the tank relative to the frame using a spring and a shock absorber, the shock absorber including a stationary mode of operation being active when the movable machine is being loaded and a moving mode of operation being active when the movable machine is in motion, the shock absorber exhibiting a first amount of dampening in the stationary mode of operation and a second amount of dampening in the moving mode of operation, the second amount of dampening being greater than the first amount of dampening, andtuning the shock absorber to adjust an amount of dampening exhibited by the shock absorber by switching between the stationary mode of operation and the moving mode of operation. 14. The method of claim 13, wherein the tuning is performed by a processor. 15. The method of claim 14, further including providing the tank in the form of a liquid natural gas tank with a cryogenic inner tank inside an outer tank. 16. The method of claim 14, further including using a sensor to generate a signal, and having the processor tune dampening based on the signal. 17. The method of claim 13, further including allowing the tank to move relative to the frame using the spring where the frame experiences a vertical load, and dampening the movement using the shock absorber.
