HPXdrive for Crane | Technologies

Functional exchange, depending on demands!

With increasing costs and environmental awareness, working efficiently is essential. When compared with a conventional cylinder-driven grab, the HPXdrive stands out thanks to its extended lifetime.

Not only maintenance downtimes are reduced but also operational expenses. The integrated shell exchange system and the different available shell options provide high flexibility on one hand, and lower the cost of ownership for additional attachments on the other hand.

The HPXdrive Standard (SD) guarantees a secure working in daily tasks. Integrated pressure relief valves keep the operation independent from the carrier‘s operating pressure. The drive unit HPXdrive can be equipped with a standard flange rotator as well as with a shaft rotator. When used in combination with a shaft rotator, there are several options to connect the rotator with the drive unit, e.g. with our fully hydraulic quick change device KM 506HD.

ALL SD-SHELLS ARE EXCHANGEABLE:

Type	HPXdrive	Opening	Closing force
KM 604HPX	SD-module	1390 mm	19 kN
KM 626HPX	SD-module	890 mm	31 kN
KM 604U HPX	SD-module	1590 mm	17 kN
KM 613HPX	SD-module	1200 mm	18 kN
KM 632HPX	SD-module	1220 mm	18 kN
KM 641HPX	SD-module	1190 & 1630 mm	14 & 18 kN

Information about the closing force refers to the max. working pressure of 250 bar.

CUSTOMER BENEFITS:

FLEXIBLE OPERATION Fast and easy response to requirements, to be more competitive.

LOW MAINTENANCE The HPXdrive has no greasing point that need to be lubricated on a daily basis. Maintenance costs and time savings.

LESS WEARThe compact and extremely robust design, without hydraulic cylinders or short hoses, lowers risk of damages.

HIGHER EFFICIENCY More power thanks to the constant closing force during the entire gripping process. Tasks are finished faster and wear is kept to a minimum.

COMPACT DESIGN The HPXdrive has a compact and very robust design, no greasing points and, when mounted with a KINSHOFER rotator, short connecting hoses are no longer needed (internal oil feedthrough).

The HPXdrive Heavy Duty (HD) is a robust drive unit for heavy duty tasks. The wear-resistant, hydrostatic bearings provide for a higher level of efficiency, resulting in higher closing forces. There are also versions for Z-cranes available with the HPXdrive Heavy Duty. The HD drive can also be equipped with either a standard flange or a shaft rotator.

Exchange of shells with HPXdrive:

Shells mounted.

Loosen 4 retaining bolts on one side.

Remove loose bolts and clamping parts and place exchange aid.

Loosen bolts on other side, Remove bolts and clamping parts and place exchange aid.

HPXdrive is loose.

Lift HPXdrive and place it above the other set of shells.

Remove exchange aids first and then bolt on clamping parts on one side. Repeat on the other side.

Shells are mounted.

Thanks to the shell exchange system you lower your fleet investment costs.

Fast and easy, just choose and switch the suitable shell option according to the task. The reliable shell exchange system features an easy loosening of the shells in case of exchange and a safe and steady holding of loads during every task. Setup times are reduced to a minimum. Both your competitiveness and working process flexibility are optimized.

CLOSING FORCE PROCESS (illustration)

Compared to conventional cylinder grabs, HPXdrive closing force is high and constant during the entire open/close cycle. Movement of the arms is generated by two hollow shafts, which run opposed, and have a helix thread, hydraulically driven by a single piston. The resulting closing force remains constant wherever the position of the shells.
