Abstract
A support assembly for a telescopic conveyor may be provided. The assembly may include at least two spaced apart bearings and a reservoir of hydraulic fluid, the bearings being coupled to the reservoir to impart force to and receive force from the hydraulic fluid. The reservoir may be configured to transmit force received from any one of the bearings to at least one other of the bearings by the hydraulic fluid. The assembly can distribute uneven loads amongst the bearings thereby maintaining contact between the bearings and the conveyor, and reducing wear on the bearings and associated components.
Claims22
A support assembly comprising at least two spaced apart bearings and a reservoir of hydraulic fluid, the bearings being coupled to the reservoir to impart force to and receive force from the hydraulic fluid, the reservoir being configured to transmit force received from any one of said bearings to at least one other of said bearings by said hydraulic fluid, wherein each bearing is coupled to the reservoir by a respective hydraulic actuator, wherein the reservoir comprises a hydraulic circuit interconnecting the respective hydraulic actuator of each bearing with the respective hydraulic actuator of the, or each, other bearing such that hydraulic fluid can flow freely between the actuators.
A telescopic assembly comprising a base structure, a second structure telescopically coupled to said base structure, and at least one support assembly supporting said second structure with respect to said base structure, wherein said at least one support assembly comprises:
- at least two spaced apart bearings and a reservoir of hydraulic fluid, the bearings being coupled to the reservoir to impart force to and receive force from the hydraulic fluid, the reservoir being configured to transmit force received from any one of said bearings to at least one other of said bearings by said hydraulic fluid, wherein each bearing is coupled to the reservoir by a respective hydraulic actuator, wherein the reservoir comprises a hydraulic circuit interconnecting the respective hydraulic actuator of each bearing with the respective hydraulic actuator of the, or each, other bearing such that hydraulic fluid can flow freely between the actuators to distribute load amongst the bearings, and wherein an accumulator is connected to said hydraulic circuit for maintaining hydraulic pressure in said hydraulic circuit.
