You have telescopic cylinders and if your able to post pictures of them I can probably help you. If you give me accurate info on the pump brand/model/type and body length with overhang I can figure the capacity for you. Assuming your truck is a "one ton" you have more than enough power but I'm happy to figure it for you if you furnish the above info. Truck equipment shops are also good repair shops for hoists and cylinders.
