Reinforced Elevator Belting width (150 mm, 5 plies)

Reinforced Elevator Belting (150 mm, 5 plies)

The 150 mm wide elevator belt in five-ply execution is a specialized traction component designed for vertical bucket elevators (grain legs) where increased resistance to tensile loads is required while maintaining compact shaft dimensions. Unlike standard solutions, this modification features a reinforced carcass, making it an indispensable element for transporting heavy bulk cargos or operating on elevators with increased lifting height, where the belt's own weight and the product create critical pressure on the traction base.

The main task of this product is to ensure stable torque transmission from the drive to the working organs (buckets) without slippage and parasitic stretching. Thanks to the increased number of fabric plies (5 cords), the elevator belt demonstrates exceptional longitudinal rigidity and a minimal percentage of relative elongation during operation. This significantly reduces the frequency of equipment shutdowns for maintenance and belt re-tensioning, which is a critical factor, especially at the height of the harvest season.

This size is the basic standard for modernizing grain cleaning complexes (ZAV type), seed calibration lines, and medium-capacity elevators operating in a continuous cycle. It is ideally compatible with metal and polymer buckets 110–130 mm wide, ensuring reliable fixation of hardware. Thanks to the reinforced carcass construction, maximum bucket seating strength is achieved, which is the key to long-term operation. Such a solution allows for confident use of the equipment in an intensive mode for transporting a wide range of products-grain, seeds, compound feeds, or granules.

Advantages of the 5-Ply Structure of the 150 mm Elevator Belt

The basis of this elevator belt's mechanical strength is its multi-ply traction carcass-in this modification, it consists of five layers of BKNL-65 fabric, connected to each other through special cushioning rubber skims. This "sandwich structure" transforms a fairly narrow belt (150 mm) into an extremely durable traction element capable of withstanding loads typically associated with wider analogs.

Main Engineering Advantages of the 5-Cord Execution of the Elevator Belt:

1. Increased Breaking Load
Each additional layer of fabric adds about 55 N/mm to the product's total strength, and the five-ply construction creates a significant safety margin, allowing this belt to be used on high-rise elevators (over 25 meters), where the long belt's own weight becomes a critical factor.

2. Resistance to Stretching
The more fabric layers, the less the belt is prone to elastic elongation under the weight of the load. For the elevator owner, this means stable operating parameters and no need to stop the elevator weekly to adjust the screw take-up mechanism (re-tensioning the belt).

3. Bucket Attachment Rigidity
With a width of 150 mm, the bucket's contact area with the belt is limited, but the increased carcass thickness (due to 5 plies) allows the bolted connection to "seat" deeper and more reliably into the belt body, eliminating play and bucket loosening even when working with heavy or damp grain.

It should be taken into account that increasing the number of layers increases not only strength but also the elasticity (stiffness) of the web. Therefore, this modification is designed taking into account the geometry of standard elevator units. It is optimized for operation on elevators of type N-10, N-20 (ZAV-20), and N-25, where the drive pulley diameter is 400–500 mm. It is on such equipment that the 5-ply structure of the elevator belt reveals its full resource potential-the bending radius on the pulley is sufficient for the smooth passage of the belt without internal overstress. This ensures an ideal balance between the rigidity needed to hold the load and the elasticity guaranteeing the durability of splice joints and the carcass itself over many seasons.

Attachment Equipment and Splicing Methods for 150 mm 5-Ply Elevator Belting

Choosing an elevator belt 150 mm wide dictates clear requirements for bucket size. According to safe operation standards, it is necessary to leave technological margins from the belt edge to the bucket edge (minimum 10–15 mm on each side) to prevent metal friction against the elevator leg walls.

Compatible Bucket Sizes for this elevator belt model are buckets with a width of 110 mm (standard N-5, N-10) and 125 mm. To ensure maximum transport efficiency for your specific product, we offer belt outfitting with various types of working organs:

• Metal - we have a full range of designs available for any task, from reinforced seamless (pressed) and classic welded models to variants folded by the "envelope" method. Such a wide choice allows finding the ideal balance between wear resistance and component cost.
• Polymer - lightweight bucket options that reduce the load on the belt and motor, allowing the transport of seed material and fragile grain without damage. An additional advantage is explosion safety-the material does not generate sparks during friction against shaft walls, eliminating the risk of grain dust ignition.

Features of Splicing the 5-cord elevator belt lie in the fact that the 5-ply web has a greater thickness compared to standard analogs, which necessitates adjustments in the choice of splicing method:

• Mechanical Fasteners (Recommended) - using special elevator belt clamps allows joining belt ends in a butt joint, without thickening. This ensures smooth, noiseless passage over pulleys and eliminates dynamic impacts inevitable with a thick seam.
• Overlap Joint (Classic Bolted Connection) - if you plan splicing by the overlap method (lap joint), note that belt ends are connected by through-mounting buckets through a double layer of the web. Recommended overlap length is not less than 1 meter (or spanning 3–5 bucket installation steps), and since the total thickness of the 5-ply belt joint is significant, elevator bolts of increased length may be required. Also, to avoid impacts against the pulley, it is recommended to perform cutting of the bottom belt layer end at an angle (chamfering), which will ensure smooth and noiseless passage of the joint through drive pulleys.

The Perforation Service (machine punching of holes with the required pitch) is particularly relevant considering the significant density and thickness of the reinforced 5-ply web. Doing this manually on-site is a labor-intensive process often leading to violation of distances between holes and uneven (skewed) bucket installation. We offer a machine perforation service on high-precision equipment, guaranteeing ideal hole alignment, fast bucket installation, and uniform load distribution across the entire width of the traction component.

Logistics, Service, and Preparation for Installation of Zavod Moroza Elevator Belting

We perfectly understand the specifics of urgent repairs at the height of the season, so we maintain a constant warehouse stock of reinforced elevator belting 150 mm wide. The policy of Zavod Moroza excludes imposing standard factory rolls on the client-we ship exactly as many meters as your elevator height requires. An important advantage of our service is the quality of web preparation-professional machine cutting ensures an ideally smooth edge without "fraying" of carcass threads, which often occurs during makeshift cutting on-site.

Moreover, to simplify your work at height, we can perform preliminary processing of elevator belt edges even at the ordering stage. If you plan an overlap connection, our specialists can immediately chamfer (bevel) the belt ends, guaranteeing its smooth running over pulleys. Such a comprehensive approach, together with the possibility of immediately picking up necessary buckets and fasteners, allows you to receive a repair kit fully ready for installation in one go, saving time and resources. So, regardless of whether you know the exact parameters or need advice on calculating the overlap and choosing mechanical elevator belt clamps-contact us. We are always in touch for operational order processing, consultations, and further professional support for your business.
