Product Introduction

Low profile hydraulic torque wrench is one kind of hydraulic torque wrench. Its drive shaft drives the socket to achieve the pre-tightening of the nut, which is often used to tighten and remove bolts of more than 1 inch (Reducers can be used for smaller size bolts). It’s generally used on special conditions, such as a relatively small working space, double nuts, too small bolts, or that nuts are too close to obstacles, etc.

TorcStark is a professional manufacturer of low clearance hydraulic torque wrenches. Our hollow hydraulic torque wrench models can cover most engineering needs. All products are made of aluminum-titanium alloy and high-strength alloy steel, with high strength, high toughness, thin design, double acting, high speed and large corner. Clip-on design and interchangeable plug-ins asks for no special tools. Its maximum working pressure is 70Mpa, and torque repeatability is up to ±3%. The 360°×360° rotating hose connector is suitable for compact occasions and is convenient for positioning. The low profile hydraulic wrench has sufficient strength design, overall reaction arm, and fewer moving parts, making it durable and reliable. Extensible metric and inch hexagonal inserts and sleeves make it possible to match multiple inserts with one power head.

TorcSkark low clearance torque wrenches are widely used in electric power (nuclear power, wind power, hydropower, thermal power), shipbuilding, metallurgy, transportation, cement, construction, aviation and other fields, winning the welcome of many customers with amazing product quality and cheap prices (TorcSkark is a low pro torque components factory, which avoids the price increase when buying from dealers, so our price is very competitive).

Low Profile Hydraulic Wrench Applications

Oil & Gas

There are many detachable connections between equipment and pipelines in a refinery, the most commonly used is flange connection. When pre-tightening the bolts, the gasket is compressed by the flange to cause elastic or plastic deformation of the gasket, so as to fill up the slight unevenness on the flange surface to achieve sealing. During operation, the gasket can retain a large sealing specific pressure and maintain a good sealing state.

Using a hydraulic spanner, the bolt pre-tightening force can be evenly and symmetrically acted on the gasket, so as to achieve a balanced and effective bolt load and complete the correct installation of the flange. Through the bolt tightening scheme, the bolt tightening operation is not only simpler, more efficient, but also safer and more accurate, which greatly reduces the labor intensity of workers and reduces the risk of flange seal leakage.

General Maintenance

In the field of large-scale machining, it is often necessary to use a hydraulic wrench to assist the work. The hydraulic torque wrench not only brings high work efficiency, but also brings more help for safety inspection. In industrial applications, hydrolic wrenches are mainly used for the maintenance of large machinery. There are strict requirements on the size of the hydraulic torque output. At this time, it is necessary to correctly calculate the output torque of the hydraulic wrench according to the job requirements, and then make the selection according to the reference standard.

In addition, the selection of industrial hydraulic spanner needs to pay attention to performance advantages to ensure that the accuracy of hydraulic wrenches reaches ±3%, the working pressure cannot exceed 600bar, and the free movement parameters are 360°×360° and 180°X360°. After understanding the advantages of hydraulic wrenches in industrial applications, there are parameters to follow when purchasing hydraulic wrenches, so that you can better judge the performance advantages of hydraulic torque spanner, so as to bring more help to the operation and processing.

Power Generation

In the future, most countries will promote the use of renewable energy to improve the carbon dioxide emitted into the atmosphere due to the burning of fossil fuels, so as to balance the release of carbon with the amount of natural absorption, so as to solve the environmental impact of the greenhouse effect caused by the carbon dioxide generated by energy consumption. , Repair and protect the ecological environment of mankind. In other words, traditional fossil energy consumption such as oil, natural gas, and coal will be greatly reduced in the future, and will be replaced by new renewable clean energy.

There is no doubt that customers involved in these industries are bound to be affected in the future. New energy and traditional energy are bound to have a trade-off relationship. In the future, wind power, photovoltaic power, biological power, nuclear power, and hydropower are bound to get better and better. As a precise maintenance and installation tool, hydraulic torque wrenches are bound to be more widely used in the future.


Mining is a tough job which requires tough workers and durable tools.
Those tools include hydraulic torque wrenches, which are at work on a wide range of mining applications, from vehicles hauling material to machinery digging deep below the earth.

Surface Mining

*Hydrolic torque wrenches are used to perform track maintenance on bulldozers.
*Electric rope shovels use hydraulic wrenches for undercarriage servicing, track maintenance and side frame removal.
*Hydraulic torque wrenches also provide track maintenance for hydraulic excavators and blast hole drill rigs, and upper rail maintenance on drag lines.

Underground Mining

*Hydraulic spanner are used for general maintenance on long wall mining systems.

Fixed Mining Equipment

*On conveyor systems, hydraulic torque wrenches are used for electric motor maintenance and gearbox maintenance.
*Hydraulic torque wrenches are used for frame bolting on crushers, and for frame bolt tensioning and shell bolt tensioning on mills.


What information should I provide if I need a low profile hydraulic torque wrench?

If any customer wants to buy low pro torque components, you’re kindly requested to provide necessary information as mentioned below:

  1. What is the maximum torque value you need?
  2. What are your bolt sizes? M39 M42 or else?
  3. What is the strength grade of the bolt? Usually it’s 10.9 or 8.8. If you don’t know the answer for Question 1, then this one is very necessary to answer.

With these details we will recommend you suitable model including wrench and reducers.

Which model should I select to replace the old model we are currently using?

Please show us the model number and picture of your old model, then we will recommend the similar.

What is the maximum torque you can make?

Up to 140,000Nm.

Are extended reaction arm and special type socket available?

Yes, we can make them as you request.

Which pump would you recommend to match the wrench?

We would recommend 3 stage electric pump EMP304 with high flow and high working efficiency.

How can I choose the right model in case the working condition is very special on my job site?

In this case it is suggested that you just need drop us an email (ID: TorcStark@gmail.com) and our sales representative will guide you to fill in a questionnaire, with this form we will recommend the suitable model for you.
