FIELD: transport.
SUBSTANCE: device comprises first and second elements, lifting mechanism coupled with first element to displace it towards second element. Third element is coupled with first one to slide through the second element. Note here that preset compressive force is applied to third element. Latch retains second element relative to third one so that, extra compressive force application to third element, first element and lifting element are isolated from said extra compressive force. Working member lifting comprises above described device including extra lower part of working member attached to distal end of third element or each of third elements so that displacement of first element shits working member lower part from its top part. Note here that preset compressive force originates due to contact between working member top and bottom parts. Chute sealer incorporates said working member lifting device.
EFFECT: higher efficiency and wear resistance.
