China Rubber Lifting Conveyor Belt Suppliers - High-Quality Industrial Factory Products for Bucket Elevators
The Rubber Lifting Belt is a high-quality industrial rubber product designed for efficient material handling. Commonly used in the installation of hoppers, this conveyor belt acts as a crucial traction component of bucket elevators, enabling the lifting and transportation of various materials. Manufactured in China, our belts are available from trusted suppliers and reliable factories. The belts are categorized based on core structure into two types: fabric core and steel wire rope core. Additionally, they are designed to meet different wear resistance requirements, classified into strong wear (D-type), moderate wear (L-type), and heat-resistant (T-type) options for conveying high-temperature materials. Choose our Rubber Lifting Belt for durability and performance in your industrial applications
1000 B 9508 4.5T × 3.0 1000 NN5 — Bucket type lifting belt with a strength specification of 1000 N/mm. Produced in August 1995. Upper cover layer: 4.5 mm (with reinforcement layer); lower cover layer: 3 mm. Belt width: 1000 mm. Core material: nylon canvas, 5 layers.
Marking Example 2 — Steel Wire Rope Core
St1000 B 9508 5T × 5T 1200 φ3.5 — Steel wire rope core bucket type lifting belt with a strength specification of 1000 N/mm. Produced in August 1995. Both upper and lower cover layers: 5 mm (with reinforcement). Belt width: 1200 mm. Steel wire rope diameter: 3.5 mm. Complies with chemical industry standard HG/T 2577-1994 "Rubber Lifting Belt".
This standard was revised in 2005 and is currently awaiting approval. The revised standard has been renamed as "Rubber or Plastic", and the strength and width specifications of fabric core and steel wire rope core lifting belts are consistent with those of general-purpose conveyor belts respectively. The covering layer performance is divided into three types:
L-Type: General Environmental Conditions
T3-Type: Heat Resistance ≤ 150°C
T4-Type: Heat Resistance at 175°C
The revised standard also specifies the requirements for punching and drilling of lifting belts, providing more comprehensive guidance for manufacturing and application.
Further Details
The rubber lifting belt is made up of multiple layers of adhesive fabric, and the core of the belt should generally be covered with adhesive. It can be classified based on different criteria:
By Usage Temperature
Heat-resistant lifting belts and ordinary lifting belts
By Core Material
Full cotton, polyester cotton interwoven, nylon, and EP lifting belts
What are the main types of rubber lifting belts available?
Rubber lifting belts are primarily classified by core material — including full cotton, polyester cotton interwoven, nylon, and EP types — and by usage temperature, which determines whether they are ordinary or heat-resistant lifting belts. They can also be categorized by covering adhesive grade: D-type (strong wear), L-type (moderate wear), and T-type (heat-resistant).
What strength specifications are available for fabric core lifting belts?
Fabric core lifting belts are available in the following strength specifications (N/mm): 100, 125, 160, 200, 250, 315, 400, 500, and above. Width options (mm) include: 150, 200, 300, 400, 500, 600, 650, 700, 800, 1000, 1200, 1400, and 1600.
What do the marking codes on rubber lifting belts mean?
The marking codes indicate key product parameters. For example, "1000 B 9508 4.5T × 3.0 1000 NN5" specifies a bucket type belt with 1000 N/mm strength, produced in August 1995, with a 4.5 mm upper cover layer, 3 mm lower cover layer, 1000 mm belt width, and 5 layers of nylon canvas core. For steel wire rope core belts, the code also includes the wire rope diameter (e.g., φ3.5).
What temperature resistance levels do rubber lifting belts offer?
According to the revised standard, the covering layer performance is categorized into three types: L-type for general environmental conditions, T3-type for heat resistance not exceeding 150°C, and T4-type for heat resistance up to 175°C. This allows users to select the appropriate belt based on their specific operating temperature requirements.
What standard does the rubber lifting belt comply with?
The rubber lifting belt currently complies with the chemical industry standard HG/T 2577-1994 "Rubber Lifting Belt." The standard was revised in 2005 and renamed "Rubber or Plastic Lifting Belt," with updated specifications for strength, width, covering layer performance, as well as punching and drilling requirements.
What strength specifications are available for steel wire rope core lifting belts?
Steel wire rope core lifting belts are available in strength specifications of St630, St800, St1000, St1250, St1600, St2000, and St2500 (N/mm). Width options (mm) include: 200, 250, 300, 350, 400, 450, 550, 600, 680, 800, 850, 1000, 1050, 1200, 1300, and 1400.
