Product Introduction
The RT25 features a Dongfeng Cummins engine and an optimized powertrain system (equipped with a lock-up torque converter), paired with an energy-efficient hydraulic system, significantly reducing fuel consumption. Fuel efficiency during high-speed operation is claimed to improve by over 20%. It incorporates lifting protection controls for overload, over-hoisting, and over-lowering, along with industry-exclusive rear axle wheel auto-centering control and an automatic travel safety protection system, substantially enhancing active safety. The ergonomic cab design, automatic transmission with manual override, and single-unit fault diagnosis ensure operator comfort and operational convenience.
Product Advantage
High mobility and efficiency
Two driving types of 4×2 and 4×4 are adopted with forwards and backwards driving function. Four steering modes are adopted , and the min. turning radius is 5.0m with better job site adaptability. Due to powerful power configuration, specific off-road tires and all-wheel drive, the crane can easily handle various tough terrains.
Powerful lifting capacity
Single-cylinder plus ropes telescoping system, stable and reliable. 4-section boom of 31m and jib of 13m with wide operation range.
Energy-saving and environmental friendly
The torque converter with lockout function has features of large torque at low speeds and high efficiency at high speeds. Elevating control system for freefall, without additional power needed.

Product Uses
1. Mining and Quarry Operations
Suitable for tasks such as lifting stone, transporting equipment components, and installing pipelines in mines and quarries. Its robust chassis structure and powerful off-road capability (maximum gradeability of 55%) enable it to handle rugged and harsh working conditions. However, attention must be paid to ground bearing capacity and equipment maintenance.
2. Road, Bridge, and Infrastructure Construction
Widely deployed at highway and bridge construction sites for hoisting precast components, steel materials, and other building supplies. Its 31-meter main boom and 13-meter jib combination delivers extended reach and superior working coverage within its tonnage class, effectively serving common low-rise construction areas.
3. Oilfields and Energy Sites
Used in oilfield and energy project sites for equipment installation, pipe handling, and maintenance support. Its three operating modes—outrigger-supported lifting, tire-supported lifting, and load-moving—adapt to diverse construction site requirements in oilfields and similar environments.
4. Ports and Warehousing Logistics
In ports and large warehousing facilities, it efficiently handles loading, unloading, and transferring of heavy cargo, machinery, and materials. Its agile maneuverability and 360° slewing capability enhance logistics efficiency.
5. Ship Repair and Emergency Response
Suitable for equipment hoisting and maintenance operations in ship repair ports, as well as emergency response at natural disaster or accident sites. Its excellent stability and reliable continuous operation capability enable it to withstand harsh environments.
Product Operate Guide
RT25 operation must be strictly standardized. Before operation, ensure outriggers are fully extended and supported on solid, level ground. Monitor the load moment indicator (LMI) throughout operation; overloading is strictly prohibited. Control boom movements smoothly via the control console, paying attention to the flexible switching between multiple steering modes. During lifting operations, a dedicated signal person must direct operations to ensure cargo is securely fastened and personnel are kept clear. After operation, fully retract and secure the boom, and perform regular maintenance. Operators must be certified.
FAQ
1. ENGINE OIL CONSUMPTION TOO HIGH?
Check for oil burning (blue smoke) or external leaks (oil seals, gaskets, fittings).
2. ENGINE COOLANT CONSUMPTION TOO HIGH?
Check for external leaks (hoses, fittings, radiator) or internal leaks (damaged cylinder head gasket, etc., accompanied by oil emulsification and white smoke).
3. ENGINE MAKING UNUSUAL NOISE (HIGH-PITCHED SOUND)?
Possible causes: fan belt slipping, damaged tensioner pulley or water pump bearing.
4. ENGINE WON'T START (STARTER MOTOR DOESN'T TURN)?
Priority checks: loose or corroded battery terminals, insufficient battery voltage, blown fuses, and faulty starter relay/magnetic switch.
5. ENGINE FAILS TO START?
Focus on fuel system: Check for depleted diesel, air in fuel lines, clogged fuel filters (coarse/fine), and proper operation of the manual fuel pump.
6. DIFFICULT COLD STARTS?
Verify proper function of glow plugs or intake air preheating system, and ensure use of diesel fuel with the correct cetane rating for current temperatures.
