High load-bearing capacity: Made of high-strength carbon steel, CNC precision machining technology, full penetration welding. Each 6-wheel lifting trolley can provide up to 1.26 tons / 2800 lbs loading capacitySafe, Stable and : Built-in 6 stainless steel bearings, adopt welded bearings and pin shafts, provide greater stability for safe use, work smoothly without any noise.Working in different positions: can be used with the pillar channel, you can set two directions of movement to make the crane work in different positions.E-Crane: There are wide mounting holes at the bottom. During the installation process, you can adjust the distance of the mounting screws to meet the location requirements of different types of electric hoists.HEAVY-DUTY CONSTRUCTION: 6-bearing trolley assembly constructed of solid hot-rolled iron for impact resistance. Galvanized to the rust resistance of the wheeled trolley. and noiseless during use, the bearings and pins are firmly welded, and work stably, bringing strength and quality Name: T Type Pulley AssemblyColour:Photo ColorMaterial:ironSize: 20 x 19 x 10cmPackage Contents:1 x T Type Pulley AssemblyOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
