![]() DETERMINATION OF SOME MAIN PARAMETERS OF THE MOBILE LIFTING WORKING PLATFORM
Vikenti Spassov1, Boris Tanev2 Self-propelled lifting working platforms are material handling equipment with cyclic operation that perform linear and vertical movement of people and freight. Basic design demands on scissor lift equipment are: - correct choice of metal for making the scissor units, easy fabrication and interchangeability of basic scissor units and hinge joints - correct choice of hydraulic lifting cylinder,- correct choice of hydraulic lift cylinder - determination of optimal locations (points) on the installation of lift cylinder to the scissor arms of the lift installation.
The lift installation must ensure regural and efficient operation of forklift work platform, so that during its operation to ensure a steady load at all scissor units and to avoid stressful situations that disrupt the normal and efficient operation. самоходна подемна ножична платформа подемна уредба сила в подемен хидравличен цилиндърSelf propellerd scissor lift work platformlift device force in lifting hydraulic cylinderVikenti Spassov Boris Tanev BIBLIOGRAPHY [1] BDS EN 280+A1 Podvizhni rabotni ploshtadki,koito se povdigat.Izchisleniya za proektirane, kriterii za ustoychivost.
