Imagine you are in class technical schools. Class is in session. Lecturer for the Department sets the course, and the students, as expected, sitting at desks and listening attentively. But here ends the theoretical part, and is unusual in that the teacher, instead of inviting listeners to go to the shop or the lab, asking them to stand in the aisles. Then presses the button on the remote, and the tables as the team descends to the level of the seats. Revved the motor… and rows of tables slowly go under the chair! Fifteen minutes — and the room is free for practice sessions.
A mobile mechanized class exists in SPTU № 178 Atasu village Anarchische district of Dzhezkazgan region.
On the frame, welded corners 90X90 mm, in two rows of ten tables installed. Seat based PA tubular frames, welded to the frame. Tables legs, instead of the hydraulic cylinders. Them twenty, they are all removed from decommissioned headers and rigidly connected with the frame. One-sided action cylinders their stocks are advancing under the pressure of the oil. Pressure relief stocks fall under the weight of the tables. Control lifting and lowering of desks is a valve R75-23, placed on the control of the Department.
The oil in the valve and then pumped the gear pump NSH-46 driven by a motor with power 10 kW and revolutions per minute, 960.
