摘要:
An overhead platform is provided with a people-carrying nacelle (8), which presents a substantially horizontal resting plane (P), and is slidingly coupled to a lifting device (9) so as to move, with respect to the lifting device (9) itself, in a direction (20) substantially orthogonal to the resting plane (P); the nacelle (8) and the lifting device (9) being reciprocally coupled by means of a ball recirculation coupling (26).
a drive unit (11); a dump body (13); and a bucket (29) for loading the body (13); the earth moving machine (10) having a lifting device (12) for lifting the body (13) fitted with the bucket (29).
摘要:
Minidumper (10) comprising: - a drive unit; - a dump body (13), possibly provided with a bucket for loading a body, and possibly provided with a raised unloading system (112). The minidumper is characterized in that the drive unit comprises at least one electric motor powered by at least one battery (101,102).

摘要:
A apparatus (300) for adjusting and controlling the actuation speeds of elements belonging to suspended platforms. The apparatus (300) comprises a motor (303), a pump (304) mechanically connected to the motor (303), an actuator cylinder (302), and a hydraulic cylinder (301) arranged between the pump (304) and the actuator cylinder (302). Furthermore, hydraulic circuit (301) comprises a slider valve (306). In apparatus (300), the oil flow rate towards the slider valve (306) and towards the actuator cylinder (302) is varied by means of control signals (SC1, SC2) sent to a logic unit (319), which controls the rpm of the variable rpm motor (303). The pumping unit (304) is a fixed displacement unit.
