Hydraulic tools: Jacks, Presses, Pullers and Cable Tools

First define the job: lifting a load, pressing parts in and out, crimping and cutting cable, bending pipe or pulling bodywork. Each type has its own heads, dies and working range, so choose a tool designed for your specific task. More on jacks: how to choose a hydraulic jack, on presses: how to choose a hydraulic press.

Hydraulic tool force is given in tonnes or kN: typically 2–50 t for jacks and presses, 6–16 t for crimping tools and 10–30 t for pullers. Choose with a 20–30 % margin so the tool does not work at its pressure limit. See how to choose hydraulic tool load capacity and working force.

Compact tools have a built-in pump, while more powerful systems use a separate 700 bar hand or foot pump that can be connected to different cylinders and heads. A two-stage pump speeds up ram approach, and for frequent work an electric or air pump is worth considering. Read how to choose a hydraulic pump and power source.

The cylinder stroke determines how far the ram can travel, and single-acting cylinders return by spring or under load. Short, low-height cylinders suit tight spaces, while hollow cylinders are used for pulling and with pullers. Read how to choose a hydraulic cylinder or ram.

In systems with a separate pump, choose flexible hoses and quick couplers rated for 700 bar and compatible with the cylinder. A pressure gauge lets you control the force and stay within the permitted pressure. See how to choose hydraulic hoses, couplers, valves and pressure gauges.

For frequent or high-volume work, crimping tools and cable cutters are also available in cordless versions, and jacks for heavy vehicles in air-hydraulic versions. These tools are listed in the sections for their power source. Read how to choose a cordless press and cable cutting tool and how to choose an air-hydraulic jack.

Choose tools with an overload relief valve, wear safety glasses and gloves, and never stay under a raised load without safety stands. See how to use hydraulic tools safely.

Clean hydraulic oil, timely seal replacement and correct storage with the ram retracted are key to a long tool life. Also check that repair kits and dies are available. Read how to store and maintain hydraulic tools and how to choose spare parts for pneumatic and hydraulic tools.
