Product Description
QY30K5C is a mature 30‑ton K‑series truck crane. It adopts five‑section U‑shaped high‑strength steel boom, optimized internal sliding block structure to reduce boom friction and deflection under heavy‑load long‑radius operation. H‑type box‑structure outriggers are equipped, and fifth outrigger is optional for enhanced stability on uneven job‑sites.
Adopting proven load‑sensing hydraulic system, the machine achieves smooth single and compound actions with excellent micro‑motion control for precise component positioning. Powered by SC9DF300.1Q5 diesel engine matched with 9‑speed transmission, rated power 221 kW, max travel speed up to 90 km/h and grade‑ability up to 40%, supporting fast relocation between construction sites.
The enclosed operator cabin is fitted with air‑conditioning, multi‑functional display and ergonomic pilot control layout. Multiple safety modules including load moment limiter, outrigger monitoring, hook height limit and anti‑tilt warning effectively avoid overload risks, fully meeting overseas construction safety standards.

Operation Guidelines
Pre‑operation Inspection Check engine oil, hydraulic oil level, tire pressure, outrigger structure, steel wire rope wear, hook safety latch and all safety alarm devices. Ensure no personnel stay inside working radius.
Site Preparation Park the crane on solid and flat ground. Fully extend four outriggers with supporting pads to keep chassis horizontal; enable fifth outrigger if required by ground condition. Lock outrigger safety mechanism. Strictly follow lifting‑capacity chart according to actual working radius and boom length.
Lifting Operation Start engine and warm‑up hydraulic system. Operate boom luffing, extension, slewing and hoisting slowly. Avoid sudden composite actions. Never exceed rated lifting load and prevent suspended load swinging.
Transfer Travel Fully retract main boom, secure hook and accessories, retract all outriggers. Confirm counterweight is firmly locked. Drive within speed limit and pay attention to road height‑limit and weight‑limit restrictions.
Post‑operation Maintenance Park on safe flat ground, retract boom and store hook properly. Shut down engine and finish daily routine inspection.
FAQ
Q1: What is the function of optional fifth outrigger?
A1: Fifth outrigger provides extra supporting point. It greatly improves whole‑machine stability when working on uneven or soft ground, reduces tipping risk under complicated working‑site conditions.
Q2: What is the maximum lifting height of QY30K5C?
A2: Max main boom length is 43 m; equipped with auxiliary jib, maximum lifting height can reach 51.1 m.
Q3: What safety devices does QY30K5C equip?
A3: Load moment limiting system, outrigger monitoring, hook height limit protection, slewing buffer and hydraulic counter‑balance valves.
Q4: What are export shipping solutions?
A4: New unit can be shipped by ro‑ro vessel or bulk carrier. Partial disassembly is available for container transportation according to customer logistics arrangement.
Q5: What about after‑sales support?
A5: Original spare parts, operation‑maintenance manuals and operation video guidance are supplied. Overseas authorized service networks cover multiple regions.
