Yes, the drive can be replaced.

Yes, the coupling type H 123.00059 must be supplied with the new pump to get it work.

General standardisation, thus significantly streamlining our product range. From 1 January 2024, all our hydraulic lifting systems (incl. service kit) will only be supplied with food-grade oil (JAX FGH-AW ISO 22). The new oil fulfils the ISO 21469 standard and the FDA 21 and EC 1935 guidelines. The new and previous oils can be mixed and used together without hesitation.

The complete hydraulic lift system product range can be found on our website.

· too little reset force
· lift system is blocked by an obstacle
· defective hand crank or pump

The options hand crank and pushbutton drive (motor) are available.

Yes, if you have a pump with a "W or H" designation, this is possible.

If you don't have a pump with a "W or H" designation, please contact our Aftersales Team, so that we can provide you with the right coupling for the conversion.

Yes, you can synchronize max. 4 pumps (40 lifting elements).
· Pump PA: 1-2 lifting elements
· Pump PF: 3-4 lifting elements
· Pump PB: 5-10 lifting elements

· Pump PA: 1-2 lifting elements
· Pump PF: 3-4 lifting elements
· Pump PB: 4-10 lifting elements

If the pumps are provided with motor drive, up to 4 pumps can be synchronized with each other. In the case of a PB Pump with 10 lifting elements, as a result one comes to 40 lifting elements.

Attention: With the hand crank one can control max. 10 lifting elements.

10 Metres

The max. system pressure is designed for 100 bar.

No, the system is supplied already vented. Consequently the hoses are completely filled with oil.

R ≥ 25mm. The hoses must be protected from external influences and must not be buckled.

You can find the instructions for this on our website under: "Operating Instructions Service kit".

The control software has been programmed, so that at both positions (above and below) half a revolution is deducted (max. nominal stroke 20mm). As a result a crash is prevented at the block position. With the hand crank option this is not however the case.

The hydraulic lift system hoses do not have to be the same length and therefore you can also shorten them.

Recommendation: Hoses as short as possible, because of the reset force.

Every lifting element has its own oil circuit and therefore an exact synchronization of the legs is guaranteed.

With a single-acting system one always requires a reset force (not necessary with the spindle solution), in order to retract the cylinder. As a result the oil is pressed back in the pump and the lifting element travels back.

Guide value: 2 min running time / 18 min pause.
