When choosing a subway slag removal machine, the following key factors need to be considered:

Applicable scenario: The subway slag removal machine is mainly used for flipping and pouring mud and lifting pipe segments in subway construction. Select appropriate models and specifications based on specific construction requirements.

Lifting capacity: The lifting capacity of the subway slag extractor is usually between 16 tons and 50 tons. Select appropriate lifting capacity according to construction requirements to ensure that it can meet engineering needs.

Structural form: There are two types of leg structures for the subway slag removal machine: A-type and U-shaped. The appropriate structural form should be selected according to the specific situation of the construction site.

Operating mechanism: The large vehicle operating mechanism adopts an 8-wheel 4-drive form and is equipped with a windproof rail clamp to ensure that the clamp of the rail clamp leaves the track during normal operation, ensuring construction safety.

Electrical equipment: including gantry, trolley (equipped with lifting mechanism, trolley running mechanism and hydraulic flipping mechanism), driver's cab and electrical equipment, etc., to ensure the normal operation and convenient operation of the equipment.

By considering the above factors comprehensively, a slag removal machine suitable for subway construction needs can be selected to ensure construction efficiency and safety.
