Product Introduction
The RT80 is equipped with a QSL engine, utilizing a dedicated energy-saving hydraulic system and a torque converter with lock-up function to effectively reduce fuel consumption. Its dual-cylinder rope-assisted telescoping system ensures stable and reliable boom extension and retraction. The equipment prioritizes safety, featuring comprehensive lifting protection controls.
Product Advantage
Energy-saving and environment friendly
Specialized energy-saving hydraulic system. 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.
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 6.1m with better job site adaptability.
Powerful lifting capacity
Developed jointly by Chinese and German engineers, with advanced design concept. 5-section boom of 43.2m and jib of 17.5m with wide operation range.

Product Uses
1. Mining and Quarry Operations
Ideal for lifting and transporting large ore blocks, stone materials, equipment components, and installing pipelines in mining and quarry sites. Its rugged chassis and robust off-road capabilities handle rough terrain with ease, while specialized off-road tires and anti-slip differential locks facilitate navigation across complex surfaces.
2. Oilfields and Energy Sites
Used in oilfield and energy project sites for equipment installation, pipe handling, and maintenance support. Multiple operating modes—including outrigger-supported lifting, tire-supported operations, and load-carrying travel—meet diverse construction site requirements.
3. Road, Bridge, and Infrastructure Construction
Widely deployed at highway and bridge construction sites for lifting precast components, steel materials, and other building supplies. Its extended boom provides excellent reach, effectively covering large work areas.
4. Ports and Warehousing Logistics
In ports and large storage facilities, it efficiently handles loading/unloading and transferring heavy cargo, machinery, and materials. Its agile maneuverability and 360° slewing capability enhance logistics efficiency.
5. Power Engineering Construction and Emergency Response
Suitable for hoisting power towers and installing power grids in electrical projects, as well as emergency response operations during natural disasters or accidents. Its excellent stability and reliable continuous operation capability address diverse requirements.
Product Operate Guide
RT80 operation must be strictly standardized. Before operation, ensure outriggers are fully extended and supported on solid, level ground. Monitor the torque limiter 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 the process, ensuring cargo is securely fastened and avoiding personnel. After operation, fully retract and secure the boom, and perform regular maintenance. Operators must hold valid certification.
FAQ
1. MULTIPLE FAULT LIGHTS ON THE EQUIPMENT OCCASIONALLY TRIGGER FALSE ALARMS SIMULTANEOUSLY?
Loose or corroded ground connections in the vehicle's electrical system cause common-mode interference.
2. ACCUMULATOR PRESSURE RETENTION TIME IS TOO SHORT?
The accumulator bladder or diaphragm is ruptured, or the charging valve is leaking. Recharge with nitrogen or replace the unit.
3. HYDRAULIC TANK LEVEL GAUGE DISPLAYS INACCURATELY?
The gauge float is stuck, or oil residue has accumulated on the outer wall of the transparent tube. Clean or replace as needed.
4. SYSTEM PRODUCES MORE FOAM AFTER HYDRAULIC OIL REPLACEMENT?
This may result from adding low-quality oil with poor anti-foaming properties, or incomplete removal of old oil during replacement, causing additive reactions between new and old oils.
5. OCCASIONAL SIGNAL DELAYS OR INTERRUPTIONS DURING REMOTE OPERATION?
Check remote control battery level, presence of strong electromagnetic interference nearby, or whether the signal receiving antenna is properly connected.
6. ABNORMALLY INTENSE VIBRATION SENSATION TRANSMITTED FROM THE CHASSIS DURING EQUIPMENT OPERATION?
Inspect whether the engine and hydraulic pump vibration damping pads have aged and failed, or whether chassis fastening bolts are loose.
