TH bucket elevator is a kind of chain bucket elevator. Compared with TD bucket elevator, the bucket bearing part is chain, which replaces the original belt drive. It uses forged ring chain as traction component, and adopts mixed or gravity unloading during operation. The lifting height is between 4.5 meters and 40 meters, and the bucket width is from 160 to 1250.
The TH Bucket Elevator where that is a high-performance vertical conveying system designed to lift bulk materials efficiently, safely and continuously. As a chain driven bucket elevator the TH model utilizes forged ring chains instead of traditional belt drives that specially offering higher tensile strength, durability for lifetime use and wear resistance.
It complies with the JB3926-85 “Vertical Bucket Elevator” industry standard and meets ISO 9001:2015 and CE certification requirements also including ensuring global quality and safety compliance. The bucket elevator have lifting heights ranging from 4.5 m to 40 m this elevator is ideal for various sectors like cement plants, mining, fertilizer processing and power generation.
When handling tiny abrasive, powdery or granular materials such as cement, sand, coal and fertilizer with reliability and operational safety are essential. The TH series chain bucket elevator stands out due to:
Ring Chain Drive System: Here The ring chain is built from forged alloy steel (HRC 58–62 model) .only that thing offering a lifespan of up to 10 years.
Heavy-Duty Performance: It really able to manages bulk materials with densities less than 1.5t/m³ and temperatures up to 250°C.
Customizable Design: Its customize desing according to clients for modular sections (2m each) allow flexible height adjustments.
Low Maintenance: Its Fewer wear components and robust steel casing reduce maintenance frequency.
Certified Quality: If talk about certification the product is CE-marked and manufactured under ISO 9001:2015 standards.
With a focus on longevity, safety and reliable performance TH bucket elevators are a preferred choice among industrial operators seeking stable vertical conveying solutions.

The working principle of a TH vertical bucket elevator involves a continuous loop of buckets attached to a ring chain that moves between a head sprocket and a boot sprocket.
Operation Process:
Feeding: Firstly the material enters via the inlet at the boot section.
Scooping: In scooping process buckets scoop materials through the rotating chain system.
Lifting: The chain driven buckets move vertically at controlled speed.
Discharging: In discharge part Material is released using gravity or mixed discharge.
Return Path: While returning the empty buckets move downward to scoop up fresh material.
This mechanism ensures smooth vertical conveying, minimal spillage, and continuous operation for high-demand applications.
TH series bucket elevators are widely used across multiple industries with including:
Cement Plants – for clinker, raw meal, and limestone handling.
Mining Operations – for ore, gravel, and coal transportation.
