Drop Forged Rivetless Chain for Overhead Conveying Systems X Type X348 X458 X658 X678
X Type drop forged rivetless chain, also referred as drop forged trolley chain, is designed to flex transversely on shorter radius and can be assembled and disassembled without the use of tool for easy installation and maintenance. The outer links are consisted of panels to increase strength of sidebars and the special pitch prevents materials from falling off the links. Drop forged rivetless chains are commonly used for overhead conveyors, trolleys, automobile industry, meat processing industry, assembly lines and so on. They can be assembled and applied with related chains products and accessories including trolleys, side-link pushers, drive dog and caterpillar dog chain.

I AttachmentThis accessory serves as a spacer and does not carry work pieces on the trolley.B AttachmentThis accessory is a formed by hot forging and has a thread stud. It has various applications including attaching trolley pairs to load bars.C AttachmentThis accessory is used to support lightweight work pieces within a trolley.Overhead Trolley Load BarsCasted Overhead Trolley Load Bars are used in conjunction with the two trolley wheels and B attachments. The main purpose is to increase the load capability over the trolley wheels.
HangerA variety of hanger styles and accessories are available to suit the design of the conveyor chain equipment. Hangers do not affect the operation of the chain. They are used where vertical lifting of weight is required, and the load must be directly above or below the trolley wheel set. If the load is heavy, we can use the load bar to connect more than 2 sets of trolley wheels, and equally distribute the load over the pair of trolleys. This will suspend the load at the center of the load bar to equalize the loading distribution over the trolley wheels.Swivel HookThe swivel hook can be forged or casted. It allows the load to be positioned at a 90-degree angle. It allows operators to move the product in a full 360 degrees while on the conveyor system. It is used with H attachments.Forged BracketThe strength of the forged bracket indirectly determines the lifespan of the conveyor system. To ensure that the chain runs according to the track design route, the forged bracket is pulled by the chain and runs along the track. It needs to bear the combined force of the chain tension when turning vertically and horizontally. The hanger is made of high-strength carbon steel and can be divided into two types: overhead and ground. Our forged brackets are forged from high-strength carbon steel. The brackets are divided into two types: Overhead and Inverted.Power TrolleyPower trolleys are an important option during the design phase of the conveyor equipment. The main function of a power trolley is to support the chain, bear the weight of hangers and the conveyor equipment parts such as pieces in work. Bearings, hangers, and forged brackets are the main components of a power trolley.
