LOAD PLATFORM JACKING-UP AND LEVELLING HYDRAULIC DRIVE |
摘要 |
FIELD: civil engineering and transport; jacking up and levelling of load platforms and self-propelled units. SUBSTANCE: hydraulic drive has hydraulic supports installed on load platform and coupled by hydraulic main lines with spaces of reciprocating meter. Meter spaces and rod spaces of hydraulic supports are connected with supply source and tank through reversible distributor. Rod spaces of controlled check valves are connected to meter spaces coupled with hydraulic supports. Rod and piston spaces of check valves are connected through additional distributor with supply source and tank. Drive has levelling spools whose drain holes communicate with tank inlet holes are connected with supply source and outlet holes, with piston spaces of check valves. EFFECT: enlarged operating capabilities. 3 cl, 3 dwgo
