* Trailer load capacity depends on all the parts — axle(s), components and materials — as well as the craftsmanship in building. All the Mechanical Elements trailers are engineered to perform as stated when built as defined, and when proper care is given in construction. Capacity for this trailer requires proper choices for parts such as the hitch, axle, wheels, tires, safety chain, decking, bolts, pins, etc. Please make sure component load capacities match or exceed the trailer total capacity, and Do not exceed manufacturers limits.
Success with the trailer — in building and for trouble-free trailer life — depends on materials, construction techniques, welding skill, assembly methods, finishing and proper loading. Proper frame set-up and weld integrity are critical, as are bolt torques, tire pressure, tire condition and the mechanics of towing. Always use proper safety and securing equipment when loading or towing a trailer.
