Hydraulic Crane – Myanmar Market Customized Version (Enhanced Cooling System)

This delivery of 13 Hydraulic Crane units is not the customer’s first purchase, but rather their third repurchase based on previous user experience.

The client is a large engineering and construction group in Myanmar. As our business expands, customer demand for hydraulic cranes continues to grow, and the core reasons for their continued preference for our products include:

1.  Reliable initial product performance – The second batch of equipment operated continuously for 12 months with zero major hydraulic system failures.
2. Customized modifications yielded results – The enhanced cooling system precisely addressed the pain points of high-temperature conditions in Myanmar.
3. Timely after-sales response – We have dedicated personnel to handle the project and dispatch representatives for regular inspections and guidance.

“Tropical” Modification of cranes

Before the equipment left the factory, the project’s technical team carried out targeted upgrades to the cooling systems of all 13 Hydraulic Crane units:

The impact of high temperature on cranes

Why is the cooling system the “Achilles’ heel” of a crane?

High-temperature thinning of hydraulic oil increases internal leakage, resulting in weak lifting power, slower operation, and accelerated aging of seals due to prolonged high temperatures. Leaks begin to appear after 3-6 months, leading to frequent maintenance. Hydraulic components are prone to operational malfunctions, jamming, or even complete failure, seriously affecting the operational safety of the crane.

1. Controlling high temperatures is crucial to ensure that the crane operates within a safe temperature range, guaranteeing stable oil viscosity and consistent lifting accuracy and speed.
2. High-temperature resistant fluororubber seals ensure excellent sealing performance at high temperatures and extend service life to over 2 years.
3. By employing more precise hydraulic components, heat generation during crane operation is reduced, and a superior hydraulic oil cooling system is incorporated to ensure stable and reliable crane operation.

Actual Verification: During continuous operation tests at an oilfield site in Magway Region, Myanmar (ambient temperature 44℃, continuous lifting for 8 hours), the enhanced hydraulic oil temperature remained stable between 68-72℃, while the oil temperature of another brand’s unmodified crane exceeded 90℃ and exhibited sluggish operation.

Customer Feedback on the Cooling System:

“The cooling system on these cranes is excellent. Ground temperatures in Myanmar often exceed 50℃ at midday. With other cranes, the hydraulic oil would become unbearably hot after just two hours of operation, causing slow operation and leaks. With these cranes, the oil temperature gauge never exceeded 70℃, and the operating lever pressure remained consistent. This is truly a product developed for the Myanmar market.”
