It is suitable for tractor-mounted timber cranes, forestry machines and truck-mounted cranes. Its hydraulic chainsaw cuts timber up to 400 mm in diameter.<\/p>\n<p>The grapple can grip, sort, move, load and cut timber without changing attachments. Its wide 1,200 mm opening makes it easier to handle logs, branches and bundled material. Combining cutting and loading reduces separate work stages in applications such as timber handling and loading logging residues.<\/p>\n<p>Electro-hydraulic control allows all functions to operate through one double-acting hydraulic circuit. Chain lubrication is automatic, and chain tensioning is manual.<\/p>\n<p>The MGS40 is manufactured in Finland at JAK\u2019s own factory using SSAB steels, including Hardox\u00ae wear-resistant steel.<\/p>\n<p><strong>Mountings<\/strong><\/p>\n<p>Rotators and mountings are available according to the customer\u2019s carrier machine and requirements.<\/p>\n","protected":false},"excerpt":{"rendered":"<ul>\n<li>Timber grapple and hydraulic chainsaw in one attachment<\/li>\n<li>Electro-hydraulic control through one double-acting hydraulic circuit<\/li>\n<li>Automatic chain lubrication<\/li>\n<li>Manual chain tensioning<\/li>\n<li>Built using Hardox\u00ae wear-resistant steel<\/li>\n<li>Made in Finland at our own factory<\/li>\n<\/ul>\n","protected":false},"featured_media":19470,"template":"","meta":{"_acf_changed":false},"product_brand":[],"product_cat":[664,346],"product_tag":[],"class_list":["post-19466","product","type-product","status-publish","has-post-thumbnail","product_cat-grapple-saws","product_cat-tree-shears-for-tractors-and-forest-machines","first","instock","shipping-taxable","product-type-simple"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.5 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>LogRunner MGS40 Loading Grapple with Saw for Timber Cranes, Forestry Machines and Truck-Mounted Cranes &#8211;
