Chainless Trolleys

Chainless 4-rail conveyor systems offer 8-wheel trolleys with exceptional stability for any conveyor application where trolley capacities do not exceed 400 pounds. All Chainless trolleys have a standard trolley body (or housing) and standard trolley connecting ball and socket joint assemblies. The trolleys are connected to adjacent trolleys with standard 1/2 diameter rod connecting bolts, and standard 3/4 diameter steel rod connecting bars. All ten trolley moving parts are jet spray lubricated, automatically, for continuous trouble-free service. The trolley is design for a conveyor system, requiring a maximum line pull of 1500 pounds.

TROLLEY CONNECTION JOINTS
Rod tension holds the ball joint against the socket seat. Case hardened ball joints and socket seats assure long trouble-free service.

TROLLEY CONNECTORS
To assure exact trolley pitch, steel bar spacer rods are machined to exact length, then drilled, and tapped at each end. Rod bolts connect the spacer rod to the trolley ball joints. As trolleys travel through horizontal or vertical curves, the spacer rods chord the arc of the curved track.

CONNECTION SLACK
Less slack is experienced with Chainless Conveyors then with other type conveyors because of the rigid spacer rod connection between trolley ball joints. The slight telescoping action of the rod rod bolt within the trolley ball and socket assembly permits a slight expansion or contraction in the system while the trolleys negotiate vertical and horizontal curves. Absence of initial line tension keeps horsepower requirements to a minimum. Trolleys are easily removed and replaced anywhere in the system.
