semi automatic knuckle coupler

Semi Automatic Knuckle Coupler SAINEER semi-automatic knuckle coupler is the mainstream heavy-load connection component designed exclusively for low-speed industrial shunting locomotives, max operating speed limited under 100km/h, not applicable for high-speed trains, metro or EMU rolling stock. It adopts Janney knuckle self-locking structure: vehicles auto-lock upon collision, only manual side lever unlocking required, no staff need to stand between carriages, greatly improving yard operation safety. Equipped with integrated large-capacity spring/hydraulic draft gear, it absorbs huge impact force during frequent shunting, start-stop and braking. Perfectly matched with SAINEER powered bogies, traction wheelsets and axle gearboxes to form one-stop locomotive running & traction system supply.
