Product Introduction
The RT40E 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
Safe and Reliable, No Worry to Handle
The product is equipped with lifting protection control system in case of overload, over-retracting and over-stretching as well as exclusive technology in this field like rear axle-wheel automatic return-control system and safety-driving automatic protection system. All these elevate its safety performance largely;
The product is equipped with top features in this field, professional matching upgrading and systematic evaluation test. And it has passed test like driving 11,000km and 10,000 times hanging. Both ensure its reliability.
Economic and Environmental Protection, with Cost Saving
The product is equipped with optical matching power transmission system and torque converter with lockout function, which decrease the oil consumption over 20% at high speed.
The one-way stabilized current control of parallel hydraulic pressure system reduces the loss of flow; the gravity drop luffing system needs no extra power and save the oil consumption.

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
To operate the RT40E Rough Terrain Crane, first ensure the outriggers are fully extended on a stable surface. Use the centralized control panel to power the engine and manage the hydraulic system. Maneuver the crane slowly using the joysticks, always observing the load moment indicator (LMI) to avoid exceeding safe limits. Prioritize safety by keeping loads within the rated capacity and maintaining clear communication with your signal person at all times.
FAQ
1. HOW SHOULD EQUIPMENT BE PROPERLY STORED?
Clean the equipment, fill fuel tanks, drain water from reservoirs, apply rust prevention to exposed metal parts, and start the engine monthly for operation.
2. WHAT CAUSES EQUIPMENT TO VEER OFF COURSE?
Check if tire pressures or track tensions are consistent, if the braking system exhibits unilateral drag, or if the transmission system has malfunctions.
3. WHAT TASKS ARE REQUIRED FOR ROUTINE MAINTENANCE?
Includes checking engine oil, hydraulic fluid, and coolant levels; cleaning the air filter; inspecting tire or track condition; and tightening all connecting components.
4. WHAT PRECAUTIONS SHOULD BE TAKEN DURING RAINY WEATHER OPERATIONS?
Prevent slipping, avoid soft ground, inspect electrical system waterproofing, and suspend operations if necessary.
5. HOW CAN EQUIPMENT EFFICIENCY BE IMPROVED?
Perform regular maintenance, operate equipment correctly, and select appropriate operating modes and attachments based on working conditions.
6. HOW SHOULD LOW BATTERY POWER BE ADDRESSED?
Check if the generator is producing power normally, inspect the battery for aging, and verify if there are electrical leaks in the circuit. Repair the charging system, replace the battery, and locate the source of the electrical leak.
