Hot winding compression springs are used in mining equipment assemblies operating under conditions of intense vibration loads on:
• Rumblings
• Crushers
• Vibrating feeders
• Vibrating tables
The characteristics of the springs fully comply with GOST 16118-70 andthe customer's technical documentation.
Cyclic durability is crucial in the operation of mining equipment springs- operating under conditions of intense vibration, load and aggressive environment.

Sustainability
Controlled heating of the workpiece during hot winding allows you to maintain a uniform microstructure and hardness of the metal along the entire length of the spring. This ensures high strength and resistance to dynamic, cyclic loads, which is critically important for reliable operation of springs in mining equipment; screens, crushers, vibratory feeders operating under conditions of intense vibration and high load.
Increased resource
Shotblasting used in the production process provides surface hardening and increased adhesion for subsequent application of protective coatings. This technology increases the life of springs by 20% and is a crucial factor when choosing mining equipment for use in aggressive conditions: dust, high humidity, abrasive particles.
Production possibilities
The production of springs for mining equipment is carried out in strict accordance with the requirements of GOST 16118-70, as well as the customer's specifications. For unique equipment, manufacturing is possible according to the provided samples and drawings. For common mining equipment models, there is a system of irreducible stocks, which ensures prompt deliveries.
Marking of springs
To reduce the installation time and routine maintenance of mining equipment, all springs have an identification system. Color coding and tags with technical parameters make it possible to quickly identify products, which minimizes equipment downtime.
Advantages of the labeling system:
• Reduction of spring replacement time by 25-30%
• Elimination of installation errors
• Optimization of spare parts inventory
• Simplification of maintenance procedures
The system has been developed taking into account the requirements of GOST and the operating conditions in the mining industry.
