The
price of a crane polyurethane buffer doesn't have a fixed value, as it's heavily influenced by many factors, resulting in a wide price range.
Price Range Reference (Rough Estimate):
Small/Light Applications (e.g., crane trolleys under 5 tons):
Smaller size, price approximately $30 - $120.
Medium/Common Applications (e.g., 10-50 ton general-purpose bridge crane trolleys/gantry cranes):
Most common sizes, price approximately $120 - $400.
Large/Heavy-Duty Applications (e.g., large-tonnage gantry cranes, metallurgical cranes):
Large size, high performance requirements, price $400 - $700.
Key Factors Affecting the Price of Crane Polyurethane Buffers:
1. Size and Specifications (Most Critical Factor):
Diameter and Length: The buffer's volume and material usage directly determine the cost. For example, a buffer for a 10-ton crane trolley will differ in size and price by tens of times from a buffer for a 200-ton gantry crane trolley.
1. Energy Absorption Value: This is a core performance parameter of the shock absorber (unit: Joules (J) or kilonewton-meters (kN·m)). The greater the energy absorbed by the shock absorber, the higher the price. You need to calculate the required energy based on the impact mass and operating speed of the crane.
2. Brand and Quality:
Due to differences in materials, manufacturing processes, design standards, and brand premium, the prices of polyurethane shock absorbers for cranes vary among different brands.
3. Crane Type and Compatibility:
Shock absorbers used on the trolley of a bridge crane are typically smaller.
Shock absorbers used on the trolley of a gantry crane (gantry crane) typically require larger sizes.
Whether it is an original part for a specific crane model (such as electric hoists or metallurgical cranes from certain brands) will also affect the price; original parts will be more expensive.
4. Purchase Channels:
Purchasing directly from the manufacturer or authorized dealers may offer a more competitive price and ensures genuine products and professional selection guidance.
To select a crane polyurethane buffer, the following crane buffer product parameters are required (how to accurately obtain the price of a crane polyurethane buffer):
Prepare key parameters: Before inquiring about a price, please confirm or find the following information:
1. Crane tonnage and type (bridge, gantry, suspended, etc.).
2. Buffer installation location (both ends of the trolley or both ends of the crane).
3. Photos of the old buffer and its nameplate (which may show the model, specifications, and manufacturer).
4. Dimensional measurement: If the old part has been removed, measure its overall length, mounting hole spacing, cylinder diameter, and other key dimensions.
Clarify the procurement purpose:
Replacing existing damaged parts: Providing information on the old part and purchasing the same model or a completely replaceable model is the safest approach.
Selecting for new projects or retrofits: Selection needs to be calculated based on the crane's design parameters (collision mass, speed). It is recommended to consult the crane manufacturer or a professional buffer supplier, who can provide technical selection services and quotes.
Example of a price inquiry:
"Hello, I need a
polyurethane buffer for a crane. It's for the trolley traveling mechanism of a 32-ton bridge crane. The existing buffer is damaged. Its dimensions are approximately: diameter 180mm, total height 250mm, center mounting hole distance 200mm. Do you have a compatible model? Please provide a price and delivery time."
