Key Technical Specifications
Understanding load charts, stability systems, and terrain adaptation is essential for safe operations with the RK250.
Rated Capacity at Various Radius
| Radius (m) | Lift Capacity (ton) | Working Height (m) | |
|---|---|---|---|
| 3.0 | 25 | 13.5 | Under load moment |
| 6.0 | 12 | 22 | Reduced capacity rule |
| 9.0 | 7 | 28 | Extended reach |
| 12.0 | 5 | 32 | Long radius lift |
Reliability on Rough Terrain
The RK250 chassis uses large rubber tires with deep treads for grip on uneven ground, reducing downtime on Hanoi ring road and mountain access projects. Its power train is tuned for durability under mixed urban and rural conditions.
Operators report stable performance during concrete pour and structural erection, where sudden load changes require responsive stability control. The integrated load moment indicator helps prevent overstress in variable work zones.
Service and Parts in Hanoi
Vietnam Co Ltd maintains a parts depot and trained technicians in Hanoi to minimize mobilization time. Warranty coverage includes hydraulic lines, boom segments, and electronic monitoring units used heavily on urban sites.
Scheduled maintenance intervals are aligned with engine hours and operating conditions rather than strict calendar dates, supporting cost efficient ownership for contractors who vary usage across projects.
Applications in Urban and Rural Projects
On Hanoi commercial towers, the RK250 handles steel beam placement, precast panels, and rooftop mechanical units without requiring auxiliary cranes. Its compact swing radius allows work near existing structures where larger cranes cannot position.
In rural upgrade programs, the machine lifts transformer assemblies, water tower segments, and bridge girders on temporary road foundations. The robust undercarriage spreads ground pressure to protect soft soils common in delta regions.
Recommended Practices for Hanoi Operations
- Check ground bearing capacity and use manufacturer approved cribbing before each major lift.
- Verify load charts for current configuration and counterweight setup specific to your site radius.
- Schedule hydraulic and engine service based on operating hours rather than only calendar time.
- Coordinate with Vietnam Co Ltd service partners for parts availability prior to project start.
- Conduct pre lift briefings with certified signalers and ground crew to confirm lift plans.
FAQ
Reader questions
What transport requirements apply for moving the RK250 between sites in Hanoi?
Road legal permits, escort vehicles for oversize loads, and route surveys are typically required; check with local authorities for axle load limits on Hanoi ring road and inner districts.
How does the load moment indicator protect the crane during lifts?
The indicator monitors radius, load weight, and boom angle to alert operators before dangerous moment levels are reached, automatically reducing permissible lift capacity as outreach increases.
Can the RK250 lift standard shipping containers in tight urban yards?
Yes, with proper spreader attachments and load distribution, the machine can lift empty containers while maintaining stability on paved surfaces and avoiding adjacent structures.
What warranty coverage is included for hydraulics and electronics sold through Vietnam Co Ltd?
Factory backed coverage typically includes pumps, valves, hydraulic hoses, boom cylinders, and electronic monitoring modules for up to 24 months under normal use and service intervals.
