FIELD: transport.
SUBSTANCE: proposed crane-manipulator plant (CMP) comprises a rotary support, multi-section pivoted-lever boom with a miniature hydraulic winch fastened on the boom head and furnished with hook, load-sensitive hydraulic system (HS) with appropriate actuators (A). It also incorporates the main adjustable axial-piston and auxiliary manual pumps, the pumps oil feed tank and two load-sensitive electrohydraulic sectional distributors with a proportional remote control. Note that CMP comprises safety devices and electrical system incorporating a portable control board built around relatively cheap and high-efficiency microprocessor components wit simple software. Note also that the proposed CMP operates in two-speed mode involving simultaneously several hydraulic system actuators.
EFFECT: simplified design, expanded operating performances, lower costs and reduced terms of production.
