FAQ about Rail Pad from GNEE RAIL
Q1: Does the rubber pad support customized size and hardness?
A: Yes. We can customize according to the rail type (such as QU120, QU100, etc.), pad length, width, thickness, embedded hole position, and other parameters provided by the customer, and adjust the hardness range to meet different load and vibration reduction requirements.
Q2: What types of crane rails are your rubber pads compatible with?
A: Our rubber pads can be widely adapted to common crane rail models such as QU70, QU80, QU100, QU120, P43, etc., and support the use of different crane rail clips, such as welded and bolted crane rail clips.
Q3: Do rubber pads need to be replaced regularly? How long is the service life?
A: Under normal use conditions (no abnormal conditions such as chemical corrosion and heavy impact), the service life of rubber pads can usually reach more than 5 years. We recommend that you conduct routine inspections of the track system every year. If the pads are found to be aged, cracked, or severely compressed, they should be replaced in time.
Q4: Can you provide third-party test reports or quality certification?
A: Yes. We can provide physical performance test reports of products (such as tensile strength, compression set, hardness, etc.), and if necessary, we can provide third-party testing or factory certification documents, such as SGS and BV, according to customer requirements.
Q5: Can the product be exported? Are there supporting customs declaration documents?
A: Yes. We have rich export experience and support export packaging. The products are accompanied by English labels, material descriptions, packing lists, certificates of origin, customs declaration documents, etc., and can be sent to Southeast Asia, the Middle East, Africa, Europe, and the United States.
Q6: How do rubber pads and crane rail clips cooperate?
A: The rubber pad is located between the bottom of the track and the steel plate, and plays a role in buffering and vibration reduction. It does not directly contact the crane rail clips. The crane rail clip is responsible for the lateral positioning of the track. We can provide pad sizes or suggestions that match the crane rail clip fixing system.
Q7: Is there a minimum order quantity requirement? Do you provide samples?
A: Conventional specifications are in stock and can support small batch orders. Customized specifications depend on quantity and process requirements. Sample testing is usually supported, and freight and fees are negotiable.
