Caterpillar Drive Chains

Caterpillar Drive Chains are vital in driving drop forged chain conveyors, so they must deliver fatigue-free operation. The U.S. Tsubaki Caterpillar Drive Chain features high-quality roller chain with drive dogs made of one-piece forged, induction-hardened steel.

Details

The entire assembly is designed to operate flawlessly in combination with our forged rivetless chain. Our chain also meets ANSI standards.

All dimensions are nominal values and for reference only

This chain is normally stocked.
Note: Power chains are available with "cam yokes" (normally every 4th pitch) or outboard rollers (normally every 6th pitch).

Engineering Steel Paver Chains

LUAN DUNG have extensive experience in the manufacture and application of Paver chains for use as drag bars assemblies in these road surfacing machines. The chains are used in twin strand format with the strands made common with flight bars. Used either as a single or double pair the chains are installed within the delivery hopper of the machine.

Details

LDC Chains produce paver chains as a principal series to original equipment and replacement applications. A multiplicity of chain types are encountered, but all following the same general format. Some of the more popular types encountered are highlighted in this section, but this is by no means exhaustive and for those chains required that are not detailed please contact our sales department.

Bush Class Chains

The heavy duty offset sidebar roller chain is designed for drive and traction purposes, and is commonly used on mining equipment, grain processing equipment, as well as equipment sets in steel mills. It is processed with high strength, impact resistance, and wearing resistance, so as to ensure safety in heavy duty applications.

Details

Heavy Duty Offset Sidebar Roller Chain

Design and Processing Advantages

1. Made of medium carbon steel, the offset sidebar roller chain undergoes processing steps like heating, bending, as well as cold pressing after annealing.

2. The pin hole is created by impact extrusion, which increases the inner surface smoothness for the hole. Thus, the matching area between the sidebar and the pin is increased, and the pins offer higher protection against heavy loads.

3. The integral heat treatment for the chain plates and rollers ensures high tensile strength. The pins additionally undergo high-frequency induction heating for the surface after integral heat treatment, ensuring high strength, high surface hardness, and wearing resistance as well. The surface carburizing treatment for the bushings or sleeves guarantees high tensile strength, superb surface hardness, and improved impact resistance. These make sure the heavy duty transmission chain has extended service life.

This series has developed in the US grain industry as an alternative to Welded steel chain in high capacity grain handling equipment. The chain construction is as LDC style with a pressed bush and pin. The link plates maintain the crank link form. There are five main standards within the series which loosely follow the Welded steel range. Other varieties can be offered.The flight formats will be as welded steel chain with polyethylene flights in various forms bolted to steel backing plates which in turn are welded to the chain.

Juice Strainer and Trash Conveyor Chains

Cast pintle chains have been the traditional selection for juice strainers and trash elevators. Engineered steel chains have also been developed as a direct alternative. (E.g. 4103 F29 and E2103) to allow for higher mechanical characteristic and enhanced corrosion resistance. In addition Luan Dung plastic division offer non-metallic alternatives that have proven performance in similar applications.

Intermediate Carrier Roller Chains

These chains are also commonly used on the Bagasse conveyor series and come in two alternative styles. One compromised of flat inner and outer bar components (Style A) , and the other assembled using a cranked sidebar instead (Style B). Both chains are more than capable for the application but the design is down to our client preference.

Details

The stud is manufactured from chrome molybdenium alloy steel, hardened and induction hardened on its full circumference. There is a single flat placed on the inside of the link so that corners, which are a stress raiser, are positioned in an area of the sidebar which is in low tension.

The seamless steel bush has a particularly heavy deoth of case hardening to match the stud. No flats are used in order to avoid stress raisers in the area of the sidebar which is in the maximum tension. Rollers are bossed and either hardened or case hardened. We also manufacture all these chains with stud and bush in 431 hardened stainless steel, a grade particularly resistant to corrosion from sugar solutions
