China Rubber Lifting Conveyor Belt Factory - Reliable Suppliers for Bucket Elevators and Material Transport Solutions
The Rubber Lifting Belt is a vital industrial rubber product widely utilized in conveyor systems across various sectors. Manufactured in China by leading suppliers and factories, this conveyor belt effectively supports the installation of hoppers and serves as a crucial traction component for bucket elevators, enabling efficient lifting and transportation of materials. Our belts are classified based on their core structure into fabric core and steel wire rope core variants. Depending on factors like wear resistance and the load capacity of the materials being conveyed, we offer three distinct types: strong wear (D-type), moderate wear (L-type), and heat-resistant (T-type) for handling high-temperature materials. Trust our China-based suppliers and factories for durable and reliable rubber lifting belts designed to meet your industrial needs
🏷️ Marking Example 1 — Fabric Core Lifting Belt1000 B 9508 4.5T × 3.0 1000 NN5
Indicates a bucket-type lifting belt with strength specification of 1000 N/mm, produced in August 1995. Upper cover layer: 4.5mm; lower cover layer: 3mm; belt width: 1000mm; core material: nylon canvas, 5 layers.
🏷️ Marking Example 2 — Steel Wire Rope Core Lifting BeltSt1000 B 9508 5T × 5T 1200 Φ3.5
Indicates a steel wire rope core bucket-type lifting belt with strength specification of 1000 N/mm, produced in August 1995. Both upper and lower cover layers: 5mm; belt width: 1200mm; steel wire rope diameter: 3.5mm. 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 for both fabric core and steel wire rope core lifting belts are now consistent with those of general-purpose conveyor belts. The covering layer performance is categorized into three types:
The revised standard also specifies the punching and drilling requirements of lifting belts.
More About Rubber Lifting Belts
The rubber lifting belt is made up of multiple layers of adhesive fabric, and the core of the belt is generally covered with adhesive. Lifting belts are classified by several criteria:
Q
What are the main strength specifications for fabric core lifting belts?
The strength specifications (N/mm) for fabric core lifting belts include: 100, 125, 160, 200, 250, 315, 400, 500, and above. These cover a wide range of industrial applications from light-duty to heavy-duty lifting operations.
Q
What is the difference between fabric core and steel wire rope core lifting belts?
Fabric core lifting belts are composed of layers of adhesive fabric (such as nylon or polyester-cotton) and are suitable for general lifting tasks. Steel wire rope core lifting belts feature embedded steel wire ropes for higher tensile strength, making them ideal for heavy-duty and high-load applications. Their strength grades range from St630 up to St2500.
Q
What do the markings on a rubber lifting belt indicate?
The marking on a rubber lifting belt encodes key product information, including the strength specification (N/mm), production date, upper and lower cover layer thicknesses, belt width, core material type, and number of layers. For example, "1000 B 9508 4.5T × 3.0 1000 NN5" indicates a 1000 N/mm nylon core belt, 1000mm wide, with 5 layers, produced in August 1995.
Q
What are the heat resistance classifications for rubber lifting belts?
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 operating temperature requirements.
Q
What industry standard does the rubber lifting belt comply with?
Rubber lifting belts comply with the chemical industry standard HG/T 2577-1994 "Rubber Lifting Belt". The standard was revised in 2005 and renamed to cover "Rubber or Plastic" lifting belts. The revised version also specifies requirements for punching and drilling of lifting belts.
Q
How are rubber lifting belts classified by wear resistance?
Rubber lifting belts are classified into three grades based on wear resistance: D-Type (Strong Wear) for highly abrasive materials, L-Type (Moderate Wear) for general-purpose use under moderate load conditions, and T-Type (Heat-Resistant) for environments with elevated temperatures. Selecting the correct grade ensures optimal belt life and performance.
