Product Description
QY25K5C‑3 is the updated version of QY25K5C 25‑ton truck crane. It adopts high‑strength U‑shaped five‑section telescopic main boom with built‑in sliding blocks to reduce boom deformation. The upgraded single variable‑pump hydraulic system delivers smooth single action and compound movements with excellent micro‑motion control. Secondary boom length measuring function expands available working combinations; auxiliary hook lifting capacity reaches 4.1 tons for frequent auxiliary hoisting tasks.
Powered by high‑performance diesel engine matched with 9‑speed transmission, the machine achieves maximum travel speed of 90 km/h and grade‑ability up to 40%, supporting rapid relocation between job‑sites. The operator cabin is furnished with air‑conditioning, multi‑function display and human‑centered control layout. Multiple safety protection modules including overload limitation, outrigger monitoring and anti‑tilt system guarantee safe operation under complex site conditions.

Operation Guidelines
Pre‑operation Inspection Check engine oil level, hydraulic oil volume, tire pressure, outrigger structure, steel wire rope wear condition, hook safety latch and all safety alarm functions before startup. Confirm no personnel stay within working radius.
Site Setup Park on solid and flat ground. Fully extend four outriggers with even supporting pads; keep chassis horizontal. Lock outrigger safety mechanism. Strictly follow lifting‑capacity chart for actual working radius and boom length.
Lifting Operation Start engine, warm‑up hydraulic system. Operate boom extension, luffing, slewing and hoisting slowly. Avoid sharp composite movements. Do not exceed rated load. Keep hoisted load stable and prevent swinging. Activate ECO mode for normal‑load tasks to save fuel.
Travel Transfer Retract boom completely, fix hook and accessories, retract all outriggers. Confirm counterweight is securely locked. Travel at permitted speed, observe road weight‑limit and height‑limit requirements.
Post‑operation Work Park on safe flat area. Retract boom and hang hook properly. Shut down engine, perform daily maintenance inspection.
FAQ
Q1: What is the difference between QY25K5C and QY25K5C‑3?
A1: QY25K5C‑3 is the upgraded version. It extends main boom to 43 m, improves max lifting torque to 1137 kN·m, adds second‑boom measuring function and raises auxiliary hook capacity to 4.1 t, with optimized hydraulic system and ECO energy‑saving logic。
Q2: Can this crane travel with full counterweight?
A2: Yes, counterweight can stay assembled for short‑distance road transfer. For long‑haul sea freight, counterweight will be disassembled for container shipment.
Q3: What are the main safety protection features?
A3: Overload limiting system, outrigger monitoring, anti‑tilt warning, slewing buffer, hook height limit protection and hydraulic counter‑balance valve.
Q4: What is the delivery condition for export?
A4: New unit can be shipped by bulk vessel or ro‑ro ship; partial disassembly for container transportation is available according to customer logistics plan.
Q5: What about after‑sales support?
A5: Supply original spare parts, operation & maintenance manual, video guidance. Local authorized service network is available in many overseas regions.
