Hydraulic lifting cylinders are used to provide a hydraulic lifting solution for heavy loads in a controlled way; they can be used to lift and move loads weighing up to 100 tonnes. They may also be used with manifolds and other applications, which can increase the lifting capacity when needed. There are many different types and brands of hydraulic lifting cylinders so there is possible to find a solution for all needs.
If you need hydraulic lifting cylinders for normal applications, there will be plenty of options available. Slightly more specialist is the low profile lifting cylinder, which will provide a solution for lifting where space is tight and a more compact cylinder is required. If you need a lifting cylinder for bespoke applications, a hollow cylinder could be the answer. This will make it possible for a threaded rod to be hooked through the middle, so it will be possible to achieve the lift you need.
There are some accessories that can be combined with a lifting cylinder to improve the lift, or to add capacity. Some of the accessories you may want to consider using include hand pumps, manifolds, hoses, powered pumps, valves, and pressure switches.
These are some of the different features of hydraulic lifting cylinders:
- Large lifting capacities of up to 100 tonnes
- Various stroke sizes
- Maximum operating pressure of 700 bar
With some universal types of hydraulic cylinder, you will get double acting cylinders with high retraction speed. This means that they are hydraulically lowered, which happens using a second connection point. The piston and bearings and materials used make these particular types of cylinders very robust and strong, so they are more suitable for use in specialist and more challenging environments.
There are many different brands of hydraulic lifting cylinder, which can be combined with many different kinds of lifting equipment and cranes. Specify a brand that will be right for you and your operations – find out about compatibilities and ensure that you will be able to use the cylinder in the way that you envisage. All paperwork must be supplied with the cylinders and you must provide training for anyone who will be lifting them and operating them, in order to comply with legislation.
When loads need to be kept in a lifted position for some time, then a hydraulic cylinder with a safety lock nut is recommended. This allows the load to be held in position very safely, and work can even take place below this load. Pumps can be separated from cylinders and pressure can be released in order for cylinders to work in much the same way as mechanical supports. Many of the objects that might be lifted and moved with these kinds of cylinders are very heavy and large, including in steel construction and large machinery.
If you have older or damaged lifting equipment, it is also possible to purchase replacement hydraulic pumps and cylinders. Be sure to check the specification and compatibility before going ahead with the purchase of the new pump or cylinder.
