Product Introduction
The strength specifications (N/mm) series of fabric core lifting belts include: 100, 125, 160, 200, 250, 315, 400, 500, and above; The width specifications (mm) series include: 150, 200, 300, 400, 500, 600, 650, 700, 800, 1000, 1200, 1400, 1600.
The strength specifications (N/mm) of the steel wire rope core lifting belt include: St630, St800, St1000, St1250, St1600, St2000, St2500; The width specifications (mm) include: 200, 250, 300, 350, 400, 450, 550, 600, 680, 800, 850, 1000, 1050, 1200, 1300, 1400.
Adhesive tape marking example 1:
1000 B 9508 4.5T × 3.0 1000 NN5 indicates that the strength specification of the bucket type lifting belt is 1000N/mm. It was produced in August 1995, with an upper cover layer thickness of 4.5mm and a reinforcement layer, a lower cover layer thickness of 3mm, a belt width of 1000mm, and a core material of nylon canvas, totaling 5 layers.
Adhesive tape marking example 2:
St1000 B 9508 5T × 5T 1200 φ 3.5 indicates that the tape specification is a steel wire rope core bucket type lifting belt, with a strength specification of 1000N/mm. It was produced in August 1995, with a thickness of 5mm for both the upper and lower cover layers and a reinforcement layer. The belt width is 1200mm, and the steel wire rope diameter is 3.5mm. Currently, this type of product complies with the 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 specifications and width specifications of fabric core lifting belts and steel wire rope core lifting belts are consistent with those of general-purpose fabric core conveyor belts and general-purpose steel wire rope core conveyor belts, respectively. The performance of the covering layer is divided into three types: general environmental conditions (L-type), heat resistance not exceeding 150 ℃ (T3 type), and heat resistance of 175 ℃ (T4 type). The revised standard also specifies the punching and drilling of lifting belts.
Frequently Asked Questions
Q: What core materials are available for rubber lifting belts?
A: The core of the lifting belts can be configured with various materials including full cotton, polyester cotton interwoven, nylon, EP (Polyester), and steel wire rope depending on application needs.
Q: How are the covering layer performance types classified?
A: The covering layer performance is divided into three distinct types: general environmental conditions (L-type), heat resistance not exceeding 150 ℃ (T3 type), and heat resistance up to 175 ℃ (T4 type).
Q: What wear-resistance grades are available for the covering adhesive?
A: Based on wear resistance and the load of the conveyed material, the covering adhesive is classified into strong wear (D-type), moderate wear (L-type), and heat-resistant type (T-type).
Q: What width specifications are standard for fabric core lifting belts?
A: The standard width specifications series for fabric core lifting belts include 150, 200, 300, 400, 500, 600, 650, 700, 800, 1000, 1200, 1400, and 1600 mm.
Q: What standard governs these rubber lifting belts?
A: Currently, these rubber lifting belts comply with the chemical industry standard HG/T 2577-1994. The standard has been revised to align strength and width specifications with general-purpose conveyor belts.
