Classification and uses of HXDL-40 Rail Trolley: 1. A simple lifting device for vertically hoisting heavy objects. It is lightweight and compact in structure. It is available in manual and electric types. ①Manual trolley: The pull chain is operated by manpower, driving the worm gear to rotate the chain drum, thereby lifting or lowering the load. It uses a load self-locking brake, where the braking torque increases with the load, ensuring safety and reliability. The working range is a vertical line below the hook. Nylon wheel aluminum plate lifting trolley: HXDL-40 Rail Trolley. Uses: Suitable for hoisting poles, stringing wires, lifting equipment, and live-line work. Features: Lightweight, durable wheels that do not damage wire ropes or cords. Available in hook type, ring type, single-side opening, and double-side opening. ②Electric trolley. The motor drives the gear transmission mechanism, wire rope drum, and hook pulley to lift or lower the load. The housing contains the wire rope drum, connected to the motor and the gear transmission with brake. There is a lifting lug on the upper part of the middle housing. After hanging, it can vertically lift loads. It can also be mounted on a running trolley to become a traveling load trolley, moving along overhead tracks to transport materials within or between workshops. 2. Trolleys are classified by the number of sheaves into single-sheave, double-sheave, and multi-sheave types. By the connection method with the load, they are divided into hook-type, chain-type, ring-type, and frame-type trolleys. Generally, small and medium-sized trolleys are mostly hook-type, chain-type, or ring-type, while large trolleys use ring-type or beam-type. By the contact between wheel and shaft, they are divided into those with sliding bearings and those with rolling bearings. By whether the side plates can be opened, there are open and closed trolleys. Open trolleys have side plates that can be opened to facilitate rope installation; they are usually single-sheave and commonly used as guide pulleys at the base of derricks. Trolleys are also classified by usage into fixed and movable types. HXDL-40 Rail Trolley is convenient to use, widely applicable, and can be manually or power operated. It can repeatedly change the direction of the traction steel rope of the trolley or trolley group and hoist or move heavy objects. Especially, trolley groups combined with winches, masts, or other lifting equipment are widely used in construction and installation operations. Mainly used in factories, mines, agriculture, electric power, construction production, docks, shipyards, warehouses for machine installation, cargo lifting, etc.
The HXDL-40 Rail Trolley also has fully sealed bearings for its traveling wheels, and the cable clamping part adopts an arc-shaped soft rubber cushion layer to prevent cable damage. The leading car and intermediate cable-carrying trolleys are equipped with anti-collision buffers to ensure that the trolleys are not impacted during starting and stopping.
