This International Standard refers to machines and equipment used on construction sites. They are divided into five groups: — assembly of machines and components for installation and extraction of piles; — equipment for preparing, conveying and compaction of concrete, mortar and processing reinforcement and formwork; — machinery and equipment for aggregate processing; — equipment for finishing work and maintenance; — machinery and equipment for general use in construction processes. The machinery and equipment presented in these particular groups are used primarily in building processes. This International Standard does not include groups of building machines such as earth-moving machinery, cranes, lifting and access machinery. 2.1.2.3 Stationary concrete batching plant Concrete mix batching plant without capability for relocation. See figures 21 and 22. 2.1.2.4 Transferable con- crete batching plant A plant for proportioning concrete mix con- stituents, capable of relocation by stripping for transportation and reassembling. See figures 21 and 22. 2.1.3 Concrete mixers Machines designed for the production of con- crete by mixing of measured (by mass or vol- ume) proportions of water, cement, aggregate and possibly chemical additives, within a cer- tain time limit. NOTE — A concrete mixer may be furnished with the following accessories: charging skip hoist, fixed or wheeled supporting frame, mechanical shovel, water dosing equipment, and a skip weighing sys- tem. See figures 23 to 27. 2.1.3.1 Batch-type concrete mixer Mixer in which charging with concrete con- stituents and discharging of the drum are car- ried out periodically, in batches. See figures 24 to 27. 2.1.3.2 Continuous-type concrete mixer Mixer in which charging with concrete con- stituents and discharging of the drum are car- ried out continuously as an uninterrupted flow. Figure 23 2.1.3.3 Gravity concrete mixer (Free-fall con- crete mixer) Machine where mixing is effected by repeat- edly elevating the mixed concrete and drop- ping it from a certain height, inside a mixing drum, during its rotation. 2.1.3.3.1 Reversing (drum) concrete mixer Gravity mixer with a reversible direction of ro- tation of the mixing drum; discharge of mixed concrete is by reversing the rotation of the drum.
