The lining walking system consists of two parts, active and passive, with a total of four sets of devices installed under the four-door frame. When the trolley travels, the power is provided by the front two sets of active traveling mechanisms, the traveling motor drives the reducer, and then the active traveling mechanism is driven by the chain drive to drive the trolley to travel, and the rear two passive traveling mechanisms follow. The walking system is generally equipped with a track clamp to ensure that the trolley will not automatically slide, especially in places with large slopes.
Lining trolley walking system and steel formwork trolleys after the demoulding, first close the gantry support jack, then tighten the gantry to support the jack, start the walking motor to walk.
