📌 Marking Example 2:
St1000 B 9508 5T × 5T 1200 φ3.5 — Steel wire rope core bucket type lifting belt. Strength: 1000 N/mm. Produced August 1995. Upper & lower cover layers: 5 mm each. Belt width: 1200 mm. Wire rope diameter: 3.5 mm. Complies with 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". The strength and width specifications of fabric core and steel wire rope core lifting belts are aligned 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 175°C
The revised standard also specifies the punching and drilling requirements of lifting belts.
● Expand
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. According to different usage temperatures, it can be divided into heat-resistant lifting belts and ordinary lifting belts. According to the different core materials, it can be divided into:
Full Cotton
Polyester Cotton Interwoven
Nylon
EP Lifting Belts
According to performance characteristics, lifting belts are further categorized. The covering adhesive is graded by wear resistance and material load:
🔥 D-Type — Strong Wear Resistance
⚙️ L-Type — Moderate Wear
🌡️ T-Type — Heat Resistant
Main width specifications (mm): 150, 200, 250, 300, 350, 400, 500, 600, and more.
❓ Frequently Asked Questions
Q
What are the main strength specifications of fabric core lifting belts?
Fabric core lifting belts are available in strength specifications (N/mm) of: 100, 125, 160, 200, 250, 315, 400, 500, and above. Width specifications (mm) range from 150 to 1600, including sizes such as 150, 200, 300, 400, 500, 600, 650, 700, 800, 1000, 1200, 1400, and 1600.
Q
What strength grades 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 range from 200 mm to 1400 mm.
Q
How do I read the marking on a rubber lifting belt?
The marking on a rubber lifting belt indicates key technical details. For example, "St1000 B 9508 5T × 5T 1200 φ3.5" tells you: it is a steel wire rope core bucket-type lifting belt with a strength of 1000 N/mm, produced in August 1995, with 5 mm upper and lower cover layers, a belt width of 1200 mm, and a wire rope diameter of 3.5 mm.
Q
What are the different types of rubber lifting belts based on heat resistance?
Based on heat resistance performance, rubber lifting belts are classified into three types: L-type (general environmental conditions), T3-type (heat resistance up to 150°C), and T4-type (heat resistance up to 175°C).
Q
What core materials are commonly used in rubber lifting belts?
Rubber lifting belts can be made with several core materials, including full cotton, polyester cotton interwoven, nylon, and EP (polyester-nylon). The choice of core material affects the belt's strength, flexibility, and suitability for different operating environments.
Q
What standard governs rubber lifting belts and has it been updated?
Rubber lifting belts originally complied with the chemical industry standard HG/T 2577-1994 "Rubber Lifting Belt." This standard was revised in 2005 and renamed "Rubber or Plastic Lifting Belt." The revised standard aligns strength and width specifications with general-purpose conveyor belts and includes updated requirements for punching and drilling of lifting belts.
