Six practical reasons our distributors, repair workshops and fleet customers stay with us order after order.
Established in 2003, we have spent more than two decades doing one thing well: excavator hydraulic components. That focus gives you deep model coverage, proven part-matching experience and stable, repeatable quality.
Our group is the appointed overseas distributor of Tong Myung Heavy Industries (Korea, TongMyung brand) and one of the larger Isuzu parts agents in China, so genuine engine and hydraulic parts reach you through an authorised channel — not the grey market.
A 90,000 m³ warehouse and improved storage system keep the most commonly requested parts on the shelf. Urgent breakdown orders are picked, packed and dispatched without waiting for production.
Genuine, OEM, rebuild and aftermarket options under one roof — pumps, travel and swing assemblies, control valves, cylinders and loose parts — consolidated in a single shipment at OEM-factory pricing.
Our overseas warehouse, operated by an Italian company, holds fast-moving items in Europe: 3–5 day delivery inside the EU, duty-free supply for member states, and local after-sales and technical support.
Every order carries a 6–12 month warranty. If a part does not match or a confirmed quality problem appears, we send replacement parts free of charge or refund the order — the risk of buying stays with us, not with you.
Authorised supply channels, independently audited international compliance and platform-backed buyer protection — built into every RITO order. Full certificates and documents are listed on our Certificate Honor page.
Our group holds an official overseas distribution authorization from Tong Myung Heavy Industries (Korea). RITO supplies genuine pumps, motors, travel devices and hydraulic replacement kits through this authorized channel.
Hydraulic components documented under European CE conformity requirements (certificate MTL23112100304R01, valid through 4 December 2028).
Hydraulic parts produced in line with RoHS restricted-substance requirements for responsible maintenance and international trade compliance.
Since 2025, RITO has supplied Fortune Global 500 companies under demanding quality, documentation and reliable delivery requirements.
Platform-backed payment, guaranteed on-time shipment and product quality protection for eligible Alibaba.com orders.
Our Guangzhou facility, stock levels and export workflow have passed direct third-party on-site inspection by Intertek.
RITO hydraulic components carry a comprehensive 6 to 12 month warranty, with free replacement or refund for confirmed manufacturing defects.

Rito Hydraulic operates with a company team of 21–60 employees. Our RITO division is composed of 6 skilled engineers and 3 professional sales teams, who work together to ensure the highest product quality, competitive prices and timely delivery on every order — from a single spare part to full container programmes.
Different customers need different things. We have a supply model for each of them.
Full-range container programmes, mixed-brand consolidation and private-label packing for resale.
Fast access to internal components, repair kits and complete assemblies so machines get back to work sooner.
Planned stock and repeat supply for mixed fleets, with documentation that keeps maintenance records clean.
Heavy-duty hydraulic components selected for abrasive, high-hour applications where downtime is expensive.
OEM and own-brand production, including marking, packaging and technical documentation to your specification.
Product quality is only half the job. The other half is making sourcing simple, safe and predictable.
| 01 | Correct part identification. Send us the machine model, serial number or a photo of the old part and our engineers will confirm the exact part number before you commit — no guessing, no wrong orders. |
| 02 | One-stop sourcing. Pumps, travel and swing assemblies, valves, cylinders and loose parts from one supplier, consolidated into a single shipment — less paperwork, lower freight cost, one point of responsibility. |
| 03 | Risk transfer on your behalf. If a part you paid for turns out to be mismatched, or a confirmed quality problem occurs within the warranty, we supply replacement parts free of charge or refund the order. The commercial risk of buying stays with us. |
| 04 | Export handling. Sea, air and express shipping, full export documentation, and private-label or neutral packaging for distributor programmes. |
| 05 | After-sales support. Technical guidance, fitting advice and warranty follow-up — normally answered within 24 hours, and available locally in Europe through our Italian warehouse operation. |
In Guangzhou we run a 90,000 m³ parts warehouse with an improved storage system, holding approximately 95% of the most commonly required excavator parts for well-known brands — Komatsu, Hitachi, Kawasaki, Caterpillar, Rexroth, Nachi-Fujikoshi, Toshiba, KYB, Nabtesco and more — on continuous stock for instant delivery.
Our overseas warehouse is operated by an Italian company, putting fast-moving items physically inside the European market. For engine assemblies and other stocked lines, that means 3–5 day delivery, duty-free supply inside the EU, and local after-sales and technical support — faster, more flexible supply with local-style service.
