Slow lifting devices Moscow
"Podemmehmash" LLC is the developer and manufacturer of lifting equipment.
In accordance with the agreement between the SEC and APM "Podemmehmash" LLC were held strength calculations of structures of low-speed hoisting devices (TSU), such as:
1) Single Column cantilevered two types of duty;
2) a two cantilever;
3) The three types of pit duty.
Computational models of all types have been divided into two parts, such as the loading platform with the carriage and the front lift. Due to the different configuration of the loading platform when operating in different modes, calculation was made for two modes: a staff and for the "catcher" mode, in case of interruption of load-bearing rope.
The computational model of the console single-column lift carrying capacity of 1.5 t
To evaluate the effect on shock strut design simulating a sudden brake platform with the carriage when the safety gear is triggered, to structural racks reactions were applied to the loading platform supports obtained from the action of the triple load arising during braking.
To simulate the shock loads generated by the action of the safety gear, conducted dynamic analysis (calculation of forced vibrations) that examined the behavior of the rack during the action of shock loads.
Conclusion : As the level of stresses arising in elements of construction cantilever rack lift when operating in normal mode , and the coefficient of the stability margin, the design satisfies the specified requirements, and thus can be realized.
When triggered, the safety device in the rack there are significant lift on the magnitude of the voltage.
