Screw jacks as a classic drive element for linear movements are offered both with trapezoidal thread spindles and with rolled or ground ball screws.
Our
gear housing allows oil lubrication and therefore high lifting speeds even with
a trapezoidal thread spindle. The range of sizes varies between a lifting
capacity of 5 kN and 1000 kN. With our comprehensive and functional accessories
you can expand your system to a complete system. We can advise you individually
and plan the lifting system according to your needs.
Depending
on the application, we can use our standard range or design a complex special
solution for you. The ability to buy cheap series drives as well as to
implement highly stressed and precise drive elements through in-house
production give us many opportunities to offer you an optimal lifting unit.
The cubic-type screw jacks of series N are lifting elements that have enjoyed great popularity among users for decades due to their shape and characteristics. The screw drives from our own production, paired with high-quality worm gearboxes, result in screw jacks with outstanding properties in terms of lifting power and smoothness.
The lifting gear units are available with trapezoidal or ball screw drive with lifting forces from 150 to 500kN. The cubic design enables the use of the screw jacks in all mounting positions. As an N version with continuous spindle or as an R version with rotating spindle in combination with a running nut, the screw jacks can be assembled for the respective application. As a further expansion stage, the lifting elements in the N version can be supplied non-rotating by means of a square protective tube or V-groove.
By connecting individual screw jacks with drive shafts lifting systems can be realized in a simple way. With the rich accessories many problems can be solved with the standard program.
The screw
jacks of the N series include 11 sizes from 2.5 - 500 kN lifting force with
stationary and rotating spindle.
The classic screw jacks of series C prove to be modern high-performance screw jacks. This is insured not only by the integrated screw lubrictation, making a relubrication of the spindle drive during operation possible, but also by the high-performance gearing, that allows higher efficiency and longer duty cycles. Due to the separated lubrication systems of gear and screw jacks the new C-series screw jacks can be used in any desired installation position. They are provided with a high quality semi-fluid grease and lubricated for life unter normal circumstances.
Various spindle types and pitches can be freely selected
in the standard range. In addition to single and multi-start trapezoidal thread
spindles, ball thread spindles with different pitches can also be used. In the
version with a stationary spindle, the nuts are compactly integrated into the
gear housing. This saves installation space. Special designs, special sizes and
special materials are possible on request.
The high-speed gearboxes supplement the range of screw jacks for extended applications with greater dynamics. Its application range is in the middle load range (12.3 kN - 117 kN). High-speed gearboxes have hardened and ground, spiral-toothed bevel gear ratios. You achieve high lifting speeds while improving efficiency.
The three sizes G1, G2 and G3 are available both as N-version with stationary, continuous spindle, as V-version protected against twisting and as R-version with rotating spindle. The 2: 1 and 3: 1 gear ratios in conjunction with high pitch ball screw spindles enable high dynamic drive solutions.k.
With ball screw spindles, high speed screw jacks achieve even better performance. All high speed screw jacks are functional in any position and can be mounted on all sides thanks to the cubic design. Depending on the application, the gear units are supplied with up to four drive shafts, so that additional bevel gear drives may be omitted. All high speed screw jacks are filled with oil at the factory.
Our High Performance Worm Gear Screw Jacks of the NA-Series are convincing of an optimized worm gear associated with a higher efficiency and longer duty cycles. By separating the gear lubrication from the spindle lubrication the NA-Series can be run with an input-speed up to 3000 1/ min. The case-hardened and grounded worm gear guarantees maximum drive torques and fatigue fracture strength.
The program
includes 6 sizes from 5 to 350 kN lifting force with stationary, non-rotating
or rotating spindle.
Spindles are provided. In addition to
using the high-performance spindles, we are able to offer you an optimal
solution for all specific special applications. We design and implement your
system according to your wishes.
Based
on our many years of experience in the development and construction of lifting
gears, we will be happy to design any specific system for you. Our range of
gears is ideal for quick deliveries, reliably and competently. We plan, develop
and design the complete system for you.
We offer high-quality accessories for all gearboxes,
which are precisely selected for your installation situation. We are also happy
to manufacture special adaptations for you on request. Our standard accessories
include all units that supplement the gearbox and are necessary for the design
of the system.
The quality of our gearboxes is an important part of our philosophy. We try to design our gearboxes according to the needs of our customers in such a way that we meet both the requirements for performance and economy.
For FLOHR, however, customer service does not end with the handover of the product. Each of our gearboxes is well documented and should give you a long service life. We also offer a full repair and maintenance service for all of our gearboxes.
In order to be able to provide any type of repair and service as quickly as possible, we offer our customers a well thought-out service strategy, which also includes the storage of special parts and a rolling exchange of strategically relevant parts. In conjunction with this, we offer a repair, maintenance and service for all of our customers' transmissions, irrespective of brand. With a quick and professional damage analysis, you will immediately receive a cost estimate for the necessary repair measures. After approval, we guarantee reliable processing of the repair or service order.
Thanks to our service strategy, we have already had very good experiences with our customers. Together with you, we agree on maintenance intervals in order to prevent damage and reduce downtimes to a minimum. However, should an unscheduled problem occur, you will be immediately supported by our team.
