Need some help with a scissor hoist, I bought a new Hino 18,000 GVW and had a custom body built that I've been unhappy with since I took delivery. The body is perfect, the hoist/mounting arrangement is the problem. I have had a few bodies built by this company (never a scissor) and they are always top notch, they purchase hoists from an outside source. The dump angle is about 53 deg. When the bed is fully raised, the majority of the weight is obviously on the rear hinge, the scissor hoist bangs any time the truck is moved with the bed fully raised. When the bed is partialy raised no problems. The body builder replaced the scissor unit once already, 1 3/4" pins through a 2" cylinder hole. I just got the truck back and the pins seem to be tighter. The body builder put wedges on the hitch plate under the rear hinge that barely come into contact when the body is fully raised. I was told that it would keep the hoist from over extending? But the body still has play(up and down) when fully raised. Not sure if the dump angle is too much, I have never had this problem on any other scissor hoist though??? The truck has only 4000 miles on it so trying straighten this out before it keeps taking a beating. Any ideas on reducing the dump angle or putting a small telescopic under body hoist on it. Any help is much appreciated, Thanks Steve
