Trolleys for Load Transportation
Trolleys are attached to the electric hoist and are responsible for transporting the electric hoist across the length of the beam. They facilitate the movement and positioning of the hoist from one point to another.
Push-Type Trolley
Electric hoists with push-type trolleys (plain trolleys) have a suspension mechanism that enables the hoist to traverse horizontally by manually dragging the hoist for a specific distance. The hoist may be pushed or pulled along the length of the beam whether the hoist is loaded or not. Among the trolley-type suspensions, push-type trolleys have the lowest positioning accuracy and require the greatest effort.
Geared Trolley
Geared trolleys are operated by a hand chain, which is manually pulled several times to make the hoist travel.Lug-mounted hoists are suspended by bolting their top to a wall or an overhead beam. They are fixed securely to the spot where the load must be lifted. They may be allowed to traverse to another position.
Electric Travel Trolley
Electric travel trolleys have an electric motor that moves the hoist a specific distance. The controls for the travel direction and speed are integrated into the electric hoist controller system. Electric travel trolleys offer higher travel accuracy and precision for the least effort.
