FAQ
1. WHO ARE WE?
XUZHOU SHANGHENG ENGINEERING MACHINERY CO.,LTD is a leading construction machinery exporter,located in Xuzhou city,Jiangsu province where Xuzhou Construction Machinery Group Inc in. We have the domestic agency rights of them more than 10years,based on the advantage of them,we also estabish long-time business with other famous brands.
2. HOW IS YOUR PRICE COMPARED WITH MANUFACTURERS/FACTORIES?
We work as the leading dealers of various leading China construction machinery manufacturers/ factories, and are constantly treated with best dealership price. From numerous comparison and feedbacks from clients, our price is more competitive than the price from manufacturers/factories.
3. HOW IS YOUR DELIVERY TIME?
In general circumstance, we can have an immediate delivery of regular machines for our clients within 7 days, because we have a variety of resources to check machines in stock, locally and nation widely, and to receive machines in timely manner. But for manufacturers/factories, it will take more than 30 days to produce the ordered machine.
4. ABNORMAL VIBRATION IN HYDRAULIC HOSES?
Internal hose lining may have flaked off and caused blockage, or loose hose clamps may induce resonance.
5. INSUFFICIENT FLOW AFTER REPLACING THE HYDRAULIC PUMP?
Check suction lines for blockages, collapsed sections, or air leaks due to poor sealing.
6. NORMAL OPERATION WHEN COLD, BUT SLOW RESPONSE AFTER WARMING UP?
Internal leakage in the hydraulic system increases with rising temperature. Focus on inspecting the clearance between the pump, valves, and motor.
