Spring Elevator Buffer

The spring elevator buffer is one of the primary and most basic types of shock absorbers used in elevator systems to absorb energy and reduce sudden impacts of the cabin or counterweight. These buffers are usually made of compressed steel springs and play an effective role in preventing damage to equipment or passengers during sudden stops. Cabin Plus, as a prominent manufacturer and supplier of elevator equipment, offers various types of spring elevator buffers with high quality and safety.

What is a Spring Elevator Buffer and How Does It Work?

The spring elevator buffer is installed at the bottom of the pit and activates when the cabin or counterweight moves below the allowed limit and approaches the pit floor. In this situation, the spring buffer absorbs the kinetic energy by compressing its internal springs, preventing a hard impact of the cabin with the floor. Due to its simple structure and affordable price, this type of buffer is commonly used in low-speed and low-capacity elevators.

Advantages of Using a Spring Elevator Buffer

• Simple Mechanical Structure: Mechanical operation without the need for liquids or electronic equipment
• Cost-Effective: Spring elevator buffers are less expensive than hydraulic or polyurethane buffers
• Easy Installation: Installing this type of buffer is simple and does not require special equipment
• Suitable for Low-Speed Elevators: Ideal for residential or commercial buildings with a limited number of floors

Common Applications of Spring Elevator Buffers

Spring elevator buffers are mainly used in systems where the cabin speed is less than 1 meter per second. They are commonly found in hydraulic elevators, small traction elevators, and buildings up to 5 floors. Additionally, these buffers are suitable when pit space is limited or a more economical buffer is needed.

Comparison with Other Types of Elevator Buffers

• Compared to Hydraulic Buffers: Less energy absorption but simpler construction
• Compared to Polyurethane Buffers: Higher durability in repeated use
• Compared to Combined Buffers: More suitable for economical and low-capacity projects

Installation and Maintenance Tips for Spring Elevator Buffers

Installation of a spring elevator buffer must be precise and at the specified position at the pit floor. It is important to ensure proper leveling and a fully stable surface beneath the buffer. Maintenance includes periodic inspection of the springs for health, rust, breakage, or excessive compression. Cabin Plus recommends that elevator buffers be checked by a technician at least every six months.
