Grasping, Cutting, Aligning - Mechanization in Forestry
The wood grapple can be used as an attachment for hydraulic excavators, allowing it to grasp and hold up to 3 tons of wood. It enables the rapid sorting and loading of large quantities of wood at road construction sites, thinning operations, and lumber markets. Additionally, the wood grapple with a chainsaw can reduce worker fatigue. As a result of years of proven performance, it has minimized penetration and damage to the wood.

basic information
The grapple for wood is used as an attachment for hydraulic excavators. It operates using hydraulic power sourced from the hydraulic oil pump of the excavator. There are two methods for sourcing the hydraulic oil: single-line piping and four-line piping. In the single-line piping method, an electromagnetic valve is placed inside the wood grapple, which distributes the oil flow to two actuators—one for rotating (motor) right and left, and the other for opening and closing the claws (cylinder). The operation method can be controlled using a dedicated grip (electric) with a switch inside the hydraulic excavator. The four-line piping method takes four oil sources from the hydraulic excavator and sends oil to each of the two actuators. This method is more complicated compared to the built-in electromagnetic valve, as it does not allow for operation using a dedicated grip (electric). There are two types of mounting: "suspension type," which is suspended by one pin, and "tilt type," which is fixed with two pins. It is compatible with the new JIS standard for excavator buckets, ranging from 0.08 to 0.45 cubic meters.

Company information
As we enter the 21st century, the social environment surrounding us is undergoing significant changes. In this context, our company has launched a new entity by taking over the vehicle-mounted and marine crane, loader, grapple, and other divisions of Nansei Co., Ltd., which has a 58-year history as an industrial machinery manufacturer, with the aim of speeding up management decisions and enabling rapid decision-making in response to market changes. The new company will focus on research and development to anticipate the rapidly changing market and create products that meet customer needs in any environment or condition. We are committed to steadily moving forward while upholding the long-familiar company name "Nansei" and inheriting the corporate culture and technology we have cultivated over the years. We kindly ask for your continued support and patronage, just as you have extended to Nansei Co., Ltd. and Nansei Wintech Co., Ltd. Addendum: Regarding the machinery sales department and various sales offices that have been engaged in the sale of forestry machinery and metal recycling machinery, they will be integrated into Okada Aiyon Co., Ltd. after April 2024. For inquiries related to cranes, loaders, grapples, etc., please contact your nearest Okada Aiyon Co., Ltd. sales office.
