Yes. Hydraulic flange spreading is one of the most common applications.
Hydraulic spreaders are widely used for flange separation during pipeline and plant shutdown work. They allow contractors to open flanges safely for gasket replacement, inspection, or maintenance without damaging flange faces. Flange spreaders are often preferred over wedges and pry bars because they provide controlled force and reduce safety risks during disassembly operations.
Wedge spreaders fit into tight gaps, while jaw spreaders provide wider opening range for general spreading work.
Wedge spreaders are compact tools designed to fit into very small gaps, making them ideal for flange separation and confined access applications. Jaw spreaders typically have a larger opening range and are used for general spreading and separation tasks where more clearance is available. Selecting the correct spreader type depends on the gap size, required force, and application.
Yes. Rebar grips are commonly used with hydraulic cylinders and rams for tensioning work.
Hydraulic cylinders provide controlled pulling force for tensioning and load testing operations. Rebar grips attach to the rebar and allow the cylinder to apply load without slipping. This setup is commonly used in heavy construction projects where precise tensioning is required. Hydraulic Rentals can supply compatible cylinder and pump packages along with rebar grip rentals.
Torque is controlled by adjusting hydraulic pressure using the pump and referencing the wrench torque chart.
Hydraulic torque wrench systems produce torque output based on hydraulic pressure. The operator sets the pump pressure to a specific PSI value and uses the manufacturer torque chart to match that pressure to the required torque output. This allows consistent bolt tightening across multiple fasteners and helps prevent over-torque or under-torque conditions. Accurate pressure gauges are essential for safe bolting performance.
Bottle jacks contain hydraulic cylinders but are considered hydraulic jacks.
Bottle jacks use an internal hydraulic cylinder mechanism to create lifting force, but the overall unit is designed as a portable self-contained lifting jack.
A mechanical ratchet jack is a manually operated lifting jack that uses a ratcheting mechanism to raise heavy loads incrementally.
Mechanical ratchet jacks use a climbing ratchet mechanism that advances the lifting system step-by-step as the operator moves the handle. These jacks provide controlled lifting and mechanical load holding without requiring hydraulic pumps or external power sources.
They are used for moving heavy industrial equipment and oversized structural components.
Hydraulic skidding systems are commonly used for transformer installation, heavy machinery relocation, bridge positioning, industrial vessel movement, turbine transport, and infrastructure construction projects. These systems provide controlled horizontal movement for loads that are too heavy or difficult to move using conventional methods
Yes, strand jacks can safely lower heavy structures in a controlled manner.
The hydraulic control system allows strand jacks to reverse their lifting sequence and lower loads with precise speed and positioning. This capability is useful for bridge demolition, equipment removal, offshore decommissioning, and controlled structural lowering applications where safety and accuracy are critical.
They can. Hydraulic Rentals offers complete rental kits with hoses, gauges, and compatible fittings.
Many hydraulic applications require a complete system, not just the pump. Electric hydraulic pump rentals are often supplied with high-pressure hoses, quick-connect couplers, pressure gauges, and fittings matched to your cylinder or tool. Using correctly rated accessories is essential for safety and performance. Hydraulic Rentals can supply complete electric pump kits to reduce setup time and ensure the system is job-ready upon arrival.
Single-acting pumps power extension only, while double-acting pumps provide pressure for both extension and retraction.
Single-acting electric pumps are designed to extend a cylinder under pressure, while the return stroke happens through spring return or load release. Double-acting electric pumps provide hydraulic pressure to both extend and retract the cylinder, allowing greater control and improved performance in many industrial applications. Double-acting pumps are often required for synchronized lifting systems, positioning operations, and any application where controlled retraction is necessary. Hydraulic Rentals can help determine the correct pump type based on your equipment.
A double-acting hydraulic cylinder uses hydraulic pressure to both extend and retract the piston.
Unlike single-acting cylinders that rely on springs or external forces for retraction, double-acting cylinders provide hydraulic control in both directions. This allows for greater precision, faster cycle times, and improved control during lifting, lowering, and positioning operations. Double-acting cylinders are commonly used in demanding heavy lifting and synchronized jacking applications.
Renting provides access to specialized hydraulic equipment without ownership costs.
Many projects only require these cylinders temporarily, making rental a practical solution.
