A strong technical office is equipped to deal with major projects using different precast prestressed systems: hollow core slabs, panels, bearing walls, columns and beams or concrete facades. All of these products are built to stand the test of time while providing added value and cost-efficiency.
Multimaster for Samcrete Building Systems
Fully automatic production sequence
Production is carried out in a fully automatic process. The individual machine functions can, however, also be operated manually. Manual control is required to determine the optimum values for the different functions, which are then fed to the automatic program control system. The fully automatic production sequence is initiated by pressing the Automatic button, and just one operator is required to supervise and feed the block machine.
Productivity and profitability of a block-making plant depend on the choice of the most suitable machine. The most important factors include:
Space requirement: a track length of 110 m is required for an 8-hour production shift of paving blocks. The machine is fed by monorail, trilateral concrete loader or forklift truck with hopper.
Cycle times: for paving blocks, cycle times vary between 25-35 seconds per cycle depending on the composition and structure of the source material, and between 35-45 seconds per cycle when adding a face mix (second layer of fine concrete).
Basic design of the Multimaster block machine
The machine comprises a torsion-resistant structure in welded design, tamper lifting device with two columns (synchronized by means of toothed racks front and rear, driven via two hydraulic cylinders), mold lifting device with four columns (synchronized by means of a toothed rack, driven via two hydraulic cylinders), travelling gear driven by means of an electric motor, and hydraulic tamper/frame and mold lock. Mold changes are quick and easy, and adjusting the machine to new block heights poses no problem at all; in addition, the machine offers ready access for cleaning and maintenance. All moving parts are of wear-resistant design.
The table below shows the expected daily output of the Knauer Multimaster for different products per 8-hour shift. The figures are based on uninterrupted material supply without any breaks in production.
