The present disclosure discloses a hydraulic machine including a support assembly and a main cylinder device connected with the support assembly. The main cylinder device includes at least two main cylinder assemblies and at least two piston rods respectively. The at least two piston rods are opposite to each other and move along opposite directions and on the same straight line. A support worktable device is disposed on the support assembly and spaced with the main cylinder device. At least two pressing mechanisms are formed between the support worktable device and the at least two main cylinder assemblies or between the support worktable device and the at least two piston rods. The at least two pressing mechanisms are configured for pressing work pieces simultaneously.

A safety power assist for a manual press is provided. In another aspect, a press includes a tool, a manual actuator, a switch and an automatically powered actuator. A further aspect of the present press employs a spring which must be compressed beyond a predetermined pinching force before a switch is activated, where switch activation causes an automatically powered actuator to advance a workpiece-contacting punch or tool.

A hydraulic forming machine, including a body provided with a feed inlet penetrating a first mounting surface, a cutting mechanism, a forming die, an ejector arranged on the forming die, and a driving mechanism. The forming die includes a movable die and a fixed die matched with each other. The cutting mechanism and the fixed die are provided on the first mounting surface of the body and respectively at two sides of the discharge end of the feed inlet. The movable die is arranged on the driving mechanism and driven by the driving mechanism to move close to or away from the fixed die in a direction perpendicular to the first mounting surface. The cutting mechanism is configured to cut a blank at an output end of the conveying inlet. The blank cut by the cutting mechanism is extruded between the fixed die and the movable die.

A method and system for compacting waste materials in a collection container. The container can be a freestanding waste container, a self-container compaction container, or a container on a waste collection vehicle. A hydraulically operated compactor blade is positioned in the raised upper portion of the container with its bottom edge a distance above the floor. A platform with a hinged portion can be included to divide the container volume into two separate compartments in order to collect different types of waste materials.

A drive apparatus includes a movable member, at least one linear electrical actuator for generating a first force, and at least one linear hydraulic actuator for generating a second force. The at least one linear electrical actuator and the at least one linear hydraulic actuator are arranged such that the first force and the second force act in parallel on the movable member in order to result in a combined force.
