Johnson Industries has its roots in the forestry industry. Launched in the 1960s, the company's first product was a grapple for yarders, followed by the introduction of many complementary products for forestry and for other industrial sectors.
The first yarding grapple featured the unique ability to close its jaws via the yarder's mainline; the harder the yarder pulls the mainline, the tighter the grapple holds the timber. This innovation was a first in the forestry industry, and set a standard of excellence unrivalled today.
Shortly after the first yarding grapples entered service, it was noticed that during steep-slope logging operations, logs being yarded had enough momentum to overrun the landing; the need of brakes on the yarder's drum winders was clear. This led to the design of a pneumatically actuated brake. The yarder brake proved so popular that Johnson Industries branched out into other markets, honing its skills, offering more complex and sophisticated braking systems. Information on brake products can be found at the company's brake website, https://brakes.ca.
The next forestry product introduced was the mechanical slack pulling carriage. The initial product offered the ability to extend a dropline for choker logging. Not satisfied with having one dedicated carriage for grapples and one for droplines, the addition of a swivel assembly combined the best of both worlds, allowing the yarder to either run chokers or fly a grapple. The enhancement brought versatility to yarding operations, allowing the operator to select the most efficient tool with minimal down-time between changes, and fewer delays due to moving the skyline.
The slack pulling carriage was followed up with the introduction of the forestry industry's first radio controlled choker bell (RCC). The RCC system offered a boost in production in conventional high-lead, helicopter, and balloon logging. The use of the RCC system with any of these timber harvesting methods is safer, more productive, and more cost effective. The product is extremely reliable, and simple to maintain.
Johnson Industries stocks a comprehensive range of parts, offers maintenance & refurbishment services for all of its products, field service, training, and commissioning assistance too.
