Couplers for Trailers
| | | |  |
| Couplers are among the most important components that need to be specified for towing industrial trailers. The reason is that great stresses are exerted on these parts when large trailers are towed, or when the trailer train is started or stopped suddenly, towing recklessly, or "dragged" around too tight a turn. Even cautious towing involves continuous wear and tear. Hamilton couplers are ruggedly constructed to withstand such service, and are designed so they will not uncouple accidentally when negotiating ramps or small obstacles. | | 
AUTOMATIC COUPLERS |
| This is the automatic coupler almost univerasally seen on caster-steer-trailers-interchangeable with most makes. Made in two capacities: the heavy duty for trailers of 3,000-8,000 lbs. capacity has steel bail and jaw sections; the light duty model for 1,000-2,500 lbs. trailers has a fabricated bail sections and smaller jaw assembly. (Both are interchangeable with comparable competative brands, but a light duty jaw will not accept a heavy duty bail.) |

MANUAL COUPLERS | |
| Lower in cost than the automatic type, these must be coupled or uncoupled manually. Another important advantage is that the wishbone half stands upright when not in use, wheile the eye protrudes minially at the rear. (The eye can be mounted to pivot out of the way entirely where necessary). In addition to the standard hook/eye version, a loop-type wishbone coupler (for use with the pintle hitches) is also offered. Available in heavy duty configurations for 3,000 lbs. to 8,000 lb. trailers, and in light duty for 1,500 to 2,500 lb. trailers. | | | | | | CP00060

| Wagon type trailers commonly employ a towing tongue with loop at the front, and a pintle hitch at the rear. Hamilton's loop is dropped forged steel; the hitches are cast steel designed for trailer capacities to 10,000 lbs. (Model 890540) and 30,000 lbs. (Model 890520) respectively. Both hitches come with safety chain and pin. Painted black. | | |  |  |

ECONOMY BAIL | CP00100 - Weight 7 1/2 lbs. |
| Available for use with the light duty jaw on trailers of 1,500 lbs. capacity or less is an "Economy" Bail, wish utilizes a fixed, spring-loaded loop in lieu of the counter-weighted type. Because its vertical movement is limited, it should be used only on smooth, level floors | |  |
