Choosing the right hydraulic jacks and lifting cylinders    

Choosing the right hydraulic jacks and lifting cylinders

Every day hydraulic jacks, lifting cylinders and other lifting equipment are used in different ways across various industry sectors. It could be as part of a major engineering project to stabilise a subsiding building, a car garage, or even to move a new bridge deck into position. Whatever the application, the choice of equipment, its safe use and correct maintenance is vital if the job is to be done safely, cost effectively and efficiently.

The right choice

As with any equipment, the right choice of jacks or lifting cylinders will make the job easier and safer. The incorrect choice of equipment can result in the job being completed poorly and not to specification, this is likely to prove costly when it is time for maintenance and servicing. With Operator’s safety at stake, corners should never be cut on the specification of hydraulic jacks or any other lifting equipment.

Hydraulic jacks

A hydraulic jack is a powerful lifting or pushing tool designed to provide effective lift over greater distances than a basic mechanical jack. They are commonly used in workshops or onsite for specialised engineering applications. Hydraulic jacks use a plunger mechanism and a non-compressible fluid, typically a hydraulic oil, to create the required pressure resulting in lifting capability. When choosing the right hydraulic jack, the following should be considered:

  • What is to be lifted?
  • The weight to be lifted
  • The height required
  • The space available to position the jack
  • The required stability when the jack is extended
  • How portable the jack needs to be?
  • Whether the motive power will come from human effort or with compressed air (a pneumatic jack)
  • Ease of servicing and maintenance

Lifting cylinders

Hydraulic lifting cylinders consist of a cylinder containing a piston which is operated by a hydraulic pump. A similar selection criteria applies when choosing between general purpose lifting cylinders, lightweight aluminium cylinders, high-tonnage construction cylinders or low-height cylinders for use in confined spaces. Add hollow plunger cylinders and long stroke/high cycle cylinders for other applications and you enter a field where specialised knowledge and experience is vital.

Key factors to understand before choosing the correct lifting cylinder

With such a wide range of lifting cylinders available, the key to successful product specification lies in understanding the following:

  • What you want to lift, push, pull bend or hold
  • The weight you want to lift (typically 50 to 1000 tonnes)
  • How far you want to lift or push it
  • High or low cycle operating regimes
  • The operating environment (indoors or onsite)
  • Available clearance to position the lifting cylinder
  • The amount of control required (maybe over multiple lift points in civil engineering applications)
  • The available hydraulic supply
  • Special protection requirements (such as piston blow out protection or safety locking for mechanical load holding)
  • Transportability
  • Is there a tensioning or testing requirement? (hollow plunger cylinders)

Lifting safety with lifting cylinders

When using both lifting cylinders and hydraulic jacks, lifting safety comes down to the correct product specification for the required job, suitable product quality, quality maintenance and regular testing. To achieve this, most users of hydraulic lifting equipment will draw on the experience and knowledge of an established expert partner.

HTL’s partnership with Holmatro ensures that expertise and industry knowledge is combined to always provide the correct product for every application.

The range of Holmatro Lifting Cylinder’s that HTL offer include:

  • Multi-Purpose Cylinders – Lifting capacity of 5 to 100 tons and a stroke length of 25 to 450mm, suitable for various applications.
  • Short Stroke Cylinders/Telescopic Cylinders – Suitable for limited spaces and general lifting activities.
  • Aluminium Cylinders – 50% lighter but are just as robust. Suitable for lifting activities requiring frequent movement of the cylinder.
  • Construction Cylinders – Lifting Capacity of 10 to 25 tons and stroke length of 125 to 250 mm. Suitable for construction for assembly purposes.
  • Flat Cylinders – With a lifting capacity of 5 to 150 tons, they are suitable for low construction heights and limited insertion spaces.
  • High Tonnage Cylinders – Lifting Cylinders with a capacity of 50 to 500 tons and stroke length of 50 to 300mm. Suitable for lifting heavy loads.
  • Locknut Cylinders –Lifting capacity of 10 to 500 tons, 150 to 300 mm stroke length. Mechanical load locking suitable for sustained loads.

With the use of Holmatro’s range of accessories, we can also provide lifting cylinders which can be safely adapted to suit various bespoke applications.
