Bonvoisin 30T Hydraulic Cylinder Jack Porta Power Ram 2.13 inch Stroke Mini Multi-Section Lifting Cylinders with Hydraulic Hand Pump for Machinery Shipbuilding

Features

• [JACK PARAMETERS]---Tonnage: 30T | Stroke 1: 0.55"| Stroke 2: 0.83" | Stroke 3: 0.75" | Total stroke: 2.13" | Self height: 2.48" | Weight: 12.13 lbs | Effective area: 0.048 sq.in. | Inner diameter 1: 1.18" | Inner diameter 2: 1.8" | Inner diameter 3: 2.5" | External diameter: 4.1"x4.9"
• [CP700 PUMP PARAMETERS]---Output pressure: 300-10000psi. Output of oil: High pressure 2.3cc; Low pressure: 13cc. Oil capacity: 900cc. Net weight: 9.5kg.
• [Multi-Section Design for Narrow Spaces] - This hydraulic cylinder is small in size, but strong in load-bearing capacity, with the self height of just 2.4 inches while delivering an impressive 2.13-inch stroke., easily fits into tight spaces, and can lift 30T heavy objects, which is especially suitable for lifting and supporting work in narrow spaces.Compared to single-section jacks, this multi-section hydraulic jack delivers precise height control, enhanced stability, and superior safety for your construction operations.
• [Manual Return Mechanism] This jack features a gravity-return design - the ram WILL NOT retract automatically after pressure release It requires light downward pressure from the load or manual assistance to reset, ensuring stable load control and prevents sudden retraction hazards.
• [Wide Applications] - This hydraulic jack can be widely used in the installation and maintenance of large and medium-sized machinery and equipment in the petroleum, electric power, metallurgical, steel, ship, bridge and other industries.However, it does NOT apply to cars.
