Subject: Помогите, пожалуйста, кто знает принцип работы лебедки! Для контекста привожу весь абзац. Непонятно второе предложение. Wire rope pulling hoister is operated in accordance with lever principle by the means of pulling the forward handle or the backward handle manually to make it move straight so as to finish such three performances as lifting, pulling and tensioning with less manual force to obtain the load of more tonnage. It will make the fourlink champing mechanic tension of the front jaw-blocks and the back ones inside the hoister move clamp --- relax to pull the forward handle or the backward handle to and forth. Спасибо!
