LD6 motor
LD6 motor series description with applications and fit questions.
What the LD6 motor description records
The company profile states that the LD6 motor is a radial piston motor described as radial piston design in cast iron, used for log grapples, excavators and loaders, with pressure up to 315 bar. Read this description as belonging to this series alone: other series pages carry their own descriptions, covering a different construction, different applications, or a different range of operating values. A reader who starts from the LD6 motor page therefore knows exactly which description belongs to this series and which descriptions belong elsewhere, and a buyer who compares series can check each description side by side without mixing values from one series into another.
When the LD6 motor is discussed in a buying conversation, the useful starting point is the category it belongs to, namely the radial piston motor range, followed by the applications named in its own description, namely log grapples, excavators and loaders that need a radial piston motor. Those two pieces of information frame the rest of the page: the category tells a reader where the series sits in the wider hydraulic components range, and the application list tells a reader where the series description places it in machine work, without turning either piece into a promise that the series will suit every machine in that category.
Where the LD6 motor is placed in machine work
The company profile places the LD6 motor in log grapples, excavators and loaders that need a radial piston motor, and that placement is written here as a description of the series section, not as a guarantee for a particular machine, a particular duty cycle, or a particular installation. A buyer who works in the applications listed above can use the application list as a first filter, then move to the fit questions later on this page, which ask for the model, the operating values and the mounting details of the machine that will actually receive the motor or valve.
Application language matters on the LD6 motor page because two machines in the same field can still differ in duty, in mounting, in port layout and in the way the hydraulic circuit is controlled, and none of those differences are visible in a short application label. For that reason this page treats every application phrase as a starting point for a specification check, and it keeps the check itself separate from the description, so that a reader does not mistake a category label for a confirmed fit.
How to read the LD6 motor figures on this page
Use the table on this page for the LD6 motor figures, and check every figure against the LD6 motor description. If a figure is not in the LD6 motor description, ask for it by series name and figure name, so the answer can be checked against the same series description. A reader who needs a figure that is not on this page should ask for it as a specification item, with the series name and the figure name written out in full, so that the answer can be checked against the same series description rather than against a different product.
Displacement, pressure, torque and speed are the kinds of values that appear in motor descriptions, and each of them answers a different question: displacement relates to how much fluid the motor takes per revolution, pressure relates to the force the circuit can apply, torque relates to the turning effort at the shaft, and speed relates to how fast the shaft turns under load. Those explanations are general reading guidance for hydraulic motors, and they do not add any value to the LD6 motor figures themselves; the figures that count for this series are only the ones in the table, and every other value on this page is either a category description or a question for the buyer to confirm.
Questions that narrow a LD6 motor choice
The company profile states that its engineering team can help select suitable models based on flow rate, pressure, displacement, torque, mounting dimensions and working conditions, and those six items are a practical checklist for any inquiry about the LD6 motor. A buyer who writes down the flow rate the circuit can deliver, the pressure the circuit will run at, the displacement range the application needs, the torque the load requires, the mounting dimensions the machine allows and the working conditions the motor will face will give the supplier a complete starting point, and will also make it easier to spot a mismatch before an order is placed. Working conditions deserve a separate line in that checklist, because temperature, contamination, duty pattern and the way the machine is started and stopped all affect how a hydraulic component behaves in service, even when the headline figures look compatible on paper.
Mounting dimensions and port layout are often the items that decide a LD6 motor replacement, because a motor that matches on displacement and pressure can still fail to fit if its shaft, its flange or its ports do not match the machine it is meant to serve. For that reason the fit questions on this page ask for mounting details in the same message as the operating values, and they ask the buyer to confirm those details against the machine drawings rather than against a memory of a previous part number alone.
Replacement notes for the LD6 motor
The company profile states that it can help select suitable replacement hydraulic motors, pumps, valves and other components according to model numbers, technical parameters, or samples, and that statement is kept here for the LD6 motor with its own conditions attached. A replacement check therefore starts from the existing model number, continues with the technical parameters of the existing part, and, where the parameters are incomplete, uses a sample or a drawing to close the gap, rather than assuming that a similar-looking series will behave in the same way. Where a series description itself names a replacement type, as some travel motor descriptions do, check that naming against the same series and its matching conditions.
A buyer who is replacing a LD6 motor part should also confirm whether the circuit, the control valve and the rest of the drive line will stay unchanged, because a replacement motor sits inside a system and a change in one component can change the behaviour of the circuit around it. That system view is part of the specification check, not an extra step after ordering, and it is the reason the inquiry guidance on this page asks for application details as well as part details.
Next step for the LD6 motor
To move from reading to inquiry, a buyer can send the series name, the application, the operating values and the mounting details together, and ask for a specification check against the LD6 motor description. Put specification questions first in the inquiry, and commercial questions after them, so the conversation stays anchored to the series described on this page. Before ordering, confirm minimum order quantity, lead time, and pricing for your specification.
For a certificate for the LD6 motor, Certificates available upon request. A buyer who needs a certificate for this series in a particular market or a particular application should name that market and that application in the inquiry, so that the answer can be given for the same scope as the question.
