Product Description
QY25K5D‑5 is the upgraded synchronous‑telescopic version of QY25K5D 25‑ton truck crane. It adopts high‑strength U‑shaped five‑section boom with increased boom‑section size by 10%, smaller boom clearance and better anti‑deflection performance. QY25K5D‑5 features single‑cylinder rope‑arrangement telescoping mechanism, realizing synchronous extension of 2‑5 boom sections without fixed telescopic sequence, eliminating frequent boom‑section switching operations; full‑boom extension time is shortened to 55 s, operation efficiency is significantly raised.
Powered by high‑torque diesel engine matched with 9‑speed transmission, the machine delivers max travel speed up to 90 km/h and 40% grade‑ability for fast site‑to‑site relocation. Large‑capacity aluminum fuel tank supports long‑hour continuous operation. The hydraulic system provides smooth compound actions and precise micro‑motion control. Operator cabin is fitted with air‑conditioning, multi‑function display and ergonomic control layout. Multiple safety modules including load moment limiter, outrigger monitoring and anti‑tilt warning ensure secure operation under complex working‑site.

Operation Guidelines
Pre‑operation Inspection Check engine oil, hydraulic oil level, tire pressure, outriggers, steel wire rope wear, hook safety latch and all safety alarm devices. Confirm no personnel stay within working radius before operation.
Site Preparation Park vehicle on solid and flat ground. Fully extend four outriggers with supporting pads, keep chassis horizontal and lock outrigger safety mechanism. Strictly follow lifting‑capacity chart according to real working radius and boom length.
Lifting Operation Start engine and warm‑up hydraulic system. For QY25K5D‑5, utilize synchronous telescoping function for quick boom adjustment. Perform boom luffing, extension, slewing and hoisting slowly; avoid sharp composite actions. Never exceed rated lifting load, prevent suspended load swinging.
Transfer Travel Fully retract boom, secure hook and accessories, retract all outriggers. Make sure counterweight is firmly locked. Drive within speed limit and pay attention to road height‑limit and weight‑limit requirements.
Post‑operation Maintenance Park on safe flat ground, retract boom and store hook properly. Shut down engine and complete daily routine inspection.
FAQ
Q1: What is the core difference between QY25K5D and QY25K5D‑5?
A1: QY25K5D‑5 is upgraded with single‑cylinder synchronous telescoping system. Boom sections 2‑5 can extend synchronously without fixed sequence, full boom extension only takes 55 seconds. It adopts reinforced boom and larger fuel tank for higher site efficiency.
Q2: Does QY25K5D‑5 support non‑synchronous boom extension mode?
A2: The default configuration is synchronous telescoping. Non‑synchronous mode can be selected according to actual working‑condition requirements.
Q3: What safety devices are equipped?
A3: Load moment limiting system, outrigger monitoring, anti‑tilt warning, slewing buffer, hook height limit protection and hydraulic counter‑balance valves.
Q4: What are export shipping options?
A4: New machine can be shipped by ro‑ro vessel or bulk carrier. Partial disassembly is available for container transportation based on customer logistics plan.
Q5: What about after‑sales support?
A5: Original spare parts, operation‑maintenance manuals and video guidance are provided. Overseas authorized service networks are available in multiple regions.
