Remote-controlled robot suitable for forested areas with scattered wood coverage

Sustainable Forest Management Innovation: Yanmar-Powered Wood Chipping Equipment Leads Global Market Transformation Against the backdrop of global advocacy for sustainable forest management, the traditional forestry industry is undergoing a profound transformation centered on ecological protection and resource recycling. Wood chipping and mulching, as a core link in forest tending and waste utilization, have become key areas of global forestry equipment innovation. Recently, a new generation of forest wood chipping and mulching equipment equipped with Yanmar engine has been launched, relying on its advanced technical performance and efficient environmental protection advantages, which is expected to set a new benchmark for the global B2B forestry equipment market. The global forestry industry is currently in a critical period of structural adjustment. Data show that the global forestry equipment market size reached 37.3 billion US dollars in 2025, with a compound annual growth rate of 4.8%, and the market demand for wood chipping and mulching equipment, which is closely related to sustainable forest management, is growing at twice the global average rate . In North America and Europe, the purchase volume of small and medium-sized multi-functional forest tending equipment has increased by about 25% from 2024 to 2025 to cope with frequent forest fires and pests . The Asia-Pacific and South American regions have become the fastest-growing markets due to the intensive management of artificial forests and increased early fire prevention investment . At the same time, only 10% of the world's forests are effectively managed, and most secondary forests and artificial forests have not yet fully exerted their carbon sequestration potential. Scientific wood chipping and mulching operations can effectively improve forest stand structure and enhance carbon sequestration capacity , which has become an important measure to promote the balance between forest ecological value and economic value.

Driven by policies and market demand, the global wood chipping and mulching equipment industry is showing three clear development trends. First, intelligence and remote control have become the core competitiveness. The shortage of skilled operators has led to more than 15% of global machinery production capacity not being effectively utilized, so remote control and automatic operation technologies are widely favored . Second, high adaptability to complex working conditions has become a rigid demand. Forest areas in different regions have diverse terrain characteristics, and equipment needs to meet the operation requirements of steep slopes and narrow spaces. Third, environmental protection and energy conservation have become mandatory requirements. Countries around the world have updated forestry machinery emission and noise standards, accelerating the elimination of old equipment . The new generation of wood chipping and mulching equipment launched this time accurately fits these trends and has significant technical advantages.In terms of core technology, the equipment is equipped with a Yanmar diesel engine with a rated power of 53.7Kw, adopting direct injection fuel supply method, which not only ensures strong power output but also improves fuel efficiency. The torque output of 269-291Nm/(1625±25rpm) provides sufficient power support for crushing operations, and the 47 tungsten steel tools with a rotation speed of 2400rpm can easily crush wood with a diameter of up to 150mm, realizing efficient processing of forest residues such as branches and dead wood. The equipment adopts hydrostatic precision transmission mode, matching high-speed motor and reducer, to achieve stepless speed regulation of working speed (0-4Km/h) and transfer speed (0-9Km/h) in both forward and reverse directions, which can be flexibly adjusted according to the density of forest residues and operation requirements.

In response to the complex terrain challenges of forest operations, the equipment is equipped with a retractable chassis, which can adjust the width of the main machine between 1690-2090mm (0-200mm adjustment on each side), and the attachment can realize lateral movement of -250~250mm, making it suitable for operations in narrow forest areas. The allowed operating inclination angle reaches 80° in any direction after engine optimization, and it can stably operate on slopes of 55°, fully meeting the operation needs of mountainous and hilly forest areas. The oil-air hybrid cooling system ensures that the equipment can maintain stable operation for a long time under high-load working conditions, extending the service life of the engine and hydraulic system.

The intelligent remote control system is another highlight of the equipment. The attachment front cover and the whole machine operation can be controlled remotely within a range of more than 150 meters, which not only ensures the safety of operators but also improves operation efficiency. The hydraulic system adopts the combination of piston pump and gear pump, with a system hydraulic capacity of 60L and a hydraulic flow rate of 140L/min for the reclamation attachment, ensuring the stable operation of the attachment. The overall dimensions of the equipment are 3700mm×1820mm×1350mm, and the main machine weight is 2900Kg (excluding attachments), which is convenient for transportation and transfer between different forest areas.

In the application process, the equipment realizes the closed-loop utilization of forest resources. The crushed wood chips can be directly covered on the forest land, which not only reduces the risk of forest fires caused by the accumulation of forest residues but also improves the soil fertility after decomposition, promoting the growth of young trees. Taking the sustainable forest management demonstration area in Hunan Province as an example, after using this equipment for chipping and mulching operations, the soil nitrogen, phosphorus, potassium and other nutrients in the forest area have increased by at least 1 time, and the water conservation capacity per hectare has reached 1730 tons . In terms of production, the equipment adopts modular assembly technology, strict quality control of key components such as hydraulic system and engine, and undergoes 100-hour continuous operation testing before leaving the factory to ensure stable and reliable performance.

For international B2B buyers, the following are common questions and professional answers about this wood chipping and mulching equipment:

Q1: What is the fuel efficiency of the equipment and how long can it operate continuously? A1: The equipment is equipped with a 45L fuel tank. Under standard operating conditions, the fuel consumption per hour is about 8-10L, and it can operate continuously for 4.5-5.5 hours after full fuel. The direct injection fuel supply method and efficient engine combustion system effectively improve fuel utilization efficiency, reducing operating costs for users.

Q2: What is the maintenance cycle of the equipment and what are the key maintenance points? A2: The regular maintenance cycle of the equipment is 250 working hours. Key maintenance points include: checking the oil level and quality of the engine and hydraulic system, cleaning the oil-air hybrid cooling system, inspecting the wear of tungsten steel tools, and testing the stability of the remote control system. The equipment adopts a modular design, which is convenient for disassembly and maintenance, and the main components have a long service life, reducing maintenance frequency and costs.

Q3: Can the equipment be customized according to different forest types and operation requirements? A3: Yes, the equipment supports personalized customization. According to the user's forest type (coniferous forest, broad-leaved forest, etc.), the size of the crushed wood, and the specific requirements of the operation terrain, we can adjust the tool material, rotation speed, chassis width, and other parameters to provide the most suitable operation solution. At the same time, we can also provide customized remote control system functions according to the user's management needs.

With the deepening of global forest sustainable management, the demand for high-efficiency, intelligent and environmentally friendly wood chipping and mulching equipment will continue to grow. This new generation of equipment relying on Yanmar's powerful engine and advanced technical configuration is expected to become a powerful assistant for global forestry enterprises to improve operation efficiency, reduce costs and realize ecological protection.
