Purely manual operation: Can be used directly at remote sites, during power outages, in confined elevated workspaces, or deep within foundation pits where electricity is unavailable; not restricted by site power conditions.
Compact and lightweight: Portable by a single person; offers far greater mobility than electric hydraulic pumps.

This is a portable hydraulic power source designed for use in environments without an external power supply. It generates high-pressure hydraulic fluid through manual operation of a lever and is primarily used for tasks such as supplementary tensioning of prestressing tendons, lifting with small jacks, checking wedge stress, and performing hydraulic operations in confined spaces lacking electricity.
Long-lever operating handle: An extended handle designed for mechanical advantage, allowing the user to generate high pressure with minimal physical effort;
Integrated reservoir base: An orange housing that incorporates the hydraulic oil chamber, featuring built-in mounting holes and a portable carrying handle;
High-pressure gauge: Displays output pressure in real-time, allowing for precise monitoring of pressure levels;
Hydraulic circuit/pressure relief valve assembly: Includes an oil outlet port and a pressure relief knob, enabling the full cycle of pressurization, pressure holding, and pressure release.
Driven purely by manual mechanical force, it can be used directly at remote construction sites, during power outages, at elevated or confined work areas, and deep within excavation pits where electricity is unavailable;
Compact and lightweight, the unit can be carried and transported by a single person, offering far greater mobility than electric hydraulic pumps.
Manual control of pumping frequency allows the user to regulate the rate of pressure increase; ideal for tasks requiring precision, such as supplementary tensioning of prestressing tendons, post-tensioning stress verification, and micro-adjustment lifting of small components;
Simple structure with no vulnerable electrical components (such as motors or solenoid valves), resulting in a very low failure rate; maintenance requires only periodic seal replacement.
Utilizes a long-lever mechanism to significantly reduce the physical force required for operation, keeping labor intensity manageable during prolonged use; the reservoir capacity is sufficient for a single operation, eliminating the need for frequent hydraulic fluid refills.
Manual pressurization is relatively slow, making it unsuitable for high-volume or long-stroke tensioning operations;
Low output flow rate results in slow extension speeds for jack cylinders; compatible only with single-strand front-gripping jacks and small hydraulic tools. IV. Application Scenarios
Re-tensioning of anchor cables and stress testing at remote construction sites without a power supply;
Spot re-tensioning of completed prestressed floor slabs and beams;
Bridge maintenance and fine-adjustment jacking of bearings;
Hydraulic operations in confined spaces inaccessible to electric hydraulic pumps.
