1. What components are included in YLCM’s transmission and hydraulic system product range?
YLCM provides a complete selection of components for construction and mining machinery. This includes hydraulic hoses, steel conveyance pipes, belt tensioners, idler pulleys, aluminum sheave assemblies, and reusable hydraulic hose fittings. These products follow strict OEM standards and are fully compatible with globally recognized brands such as Caterpillar, Komatsu, Hitachi, Cummins, and Donaldson.
2. How do I choose the right hydraulic hose or conveyance pipe?
Choosing the correct hose or pipe depends on key operating factors such as working pressure and pulsation frequency, the expected temperature range, compatibility with hydraulic oil, coolant, fuel, or air, and environmental conditions involving abrasion, corrosion, shock, or dust. YLCM also provides part-number matching for direct OEM replacement.
3. What advantages do YLCM conveyor pipes offer for mining operations?
YLCM conveyor pipes are engineered for high durability using cold-drawn steel and zinc-plated corrosion protection. They ensure stable and efficient flow of abrasive materials such as iron ore, copper ore, and aggregates. They also deliver long service life, reduced downtime, and full compatibility with common mining conveyor systems.
4. How durable are YLCM hydraulic hoses?
YLCM hydraulic hoses are built with special synthetic rubber and a four-layer steel-wire reinforcement structure that supports up to 42 MPa of working pressure. They operate reliably from –45°C to 130°C, offer strong impact and aging resistance, and provide up to 40% longer service life in abrasive environments. These hoses have been proven in harsh climates across Central Asia, Africa, Russia, and Southeast Asia.
5. What are the benefits of reusable hydraulic hose fittings?
YLCM reusable fittings allow quick field installation without the need for crimping equipment. They maintain excellent sealing performance even after repeated assemblies and have passed more than one million pressure cycle tests. They are ideal for emergency repairs, remote mining operations, and cost-efficient maintenance scenarios.
6. What makes YLCM belt tensioners and pulleys reliable?
YLCM belt tensioners and pulleys are manufactured using high-strength ductile iron or forged steel and processed with high-precision machining standards. Dynamic balancing ensures low vibration and stable operation, while tight tolerances maintain accurate belt tension and reduce slippage and premature wear. These components perform reliably under high-load and high-vibration conditions.
7. What advantages do aluminum sheave assemblies provide?
YLCM aluminum sheaves are forged from high-strength alloy and surface-hardened for long-term durability. Their lightweight design lowers system inertia, improves power transmission efficiency, and supports smooth operation even in frequently vibrating machinery. This results in extended service life and reduced energy consumption.
8. Are YLCM components compatible with major machinery brands?
Yes. YLCM transmission and hydraulic components are compatible with Caterpillar, Komatsu, Hitachi, Cummins, Donaldson, and most other global manufacturers. Customers can simply provide an OEM part number or equipment model to ensure precise fit and interchangeability.
9. How does YLCM ensure durability and quality control?
YLCM products undergo strict dimensional inspections, pressure and impulse testing, dynamic balancing, corrosion testing, and material fatigue verification. Through long-term collaboration with over 20 global OEM partners, each product is guaranteed to meet or exceed OEM performance and safety requirements before shipping.
10. Does YLCM support low MOQ or custom orders?
Yes. YLCM offers flexible order quantities for both small-batch and bulk purchase needs. Custom options are available for hose lengths, pressure ratings, pipe specifications, and special pulley or tensioner requirements. This flexibility makes YLCM suitable for repair workshops, distributors, contractors, and mining fleet operators.
11. How fast can YLCM ship orders?
In-stock products are typically shipped within one to three days. Customized parts usually require five to fifteen days depending on the specification. Global air, sea, and railway logistics options are available to help minimize equipment downtime.
12. Does YLCM provide technical support?
