Cordless Impact Wrench Designs and Information

What is a Cordless Impact Wrench?

A cordless impact wrench is most usually a battery powered tool designed to tighten a nut or other fixing, although other varieties do exist. An impact wrench works by using a motor to spin a mass inside the tool called a hammer. The hammer stores energy which is rapidly transferred to the drive shaft of the tool, which is called the anvil. The power transfer occurs very fast and is deliberately intermittent. Peak torque can be very high, but as this transfer process only occurs for a short period of time very little of the energy makes its way back to the tools operator.

What Designs are Available?

The usual design for a light industrial cordless impact wrench is very similar to that used in automotive designs. That is to say that it is a small torque gun style of product. The difference between a battery powered tool and one powered by compressed air comes from the fact that the power comes from a batter inserted into the base of the handle, rather than a compressed air line.

These pistol style impact wrenches are the more powerful of the cordless designs available, but for jobs where access is limited they can be too bulky to use and so another format is required.

Angle head cordless impact wrenches are used where there is a desire for mobility and increased flexibility of use. A typical tool in this class can offer a number of head positions, not just 90 degrees and so can be used in a variety of positions as demanded by the work environment.

What are the Advantages of a Cordless Impact Wrench?

Cordless power tools are generally less powerful that their corded cousins, there is no denying it, but the gain in flexibility of use is great. If work is to occur at a distance from a power source then a cordless tool is a huge help as all that is required is a few batteries and work can continue with minimal disruption.

Cordless impact wrenches are also safer in the workplace as they leave no dangling cables to trip over.

Angle head tools are designed for ease of use in tight working environments and generally come with their own LED lights as natural light is often restricted in these cramped environments. While these tools lack the power of more conventional pistol grip designs they do have exception reach due to their elongated design and narrow heads. The can be excellent additions to an automotive workshop for this reason alone.

While cordless impact wrenches will never replace heavier industrial units in terms of power there is no doubt that they do offer increased flexibility of working. Surely any workplace that values safety of the workforce should consider replacing old cabled tools with a safer alternative that is a cordless impact wrench?

Overseas Manufacturing and Clearing Goods Through Customs

When importing into a country, there are a number of terms, regulations and procedures an importer should be familiar with. The following is a guide of different issues to be aware of when importing.

For first time importers, it is highly advisable to pay a customs broker to enter and clear goods through customs. Customs brokers are licensed by the countries in which they operate, and they act on behalf of the importer to file the necessary documents for products to enter a country at the port-of-entry. Depending on their relationship with their client, they may also pay customs duties and other importing expenses on their client's behalf. Finally, they advise importers about issues of which they may need to be aware such as country or origin marks and other issues importers need to be aware of.

When choosing a customs broker, the importer should first make sure they can enter goods at the arrival port. In the US, customs brokers are licensed by the US Customs and Border Protection Service.

Prior to placing an order with a manufacturer, the relevant nation's customs agency and the importer's customs broker should be consulted to avoid possible problems such as the following:

  • Any legal issues that may exist with the product in the country of import.
  • Finding out after the product arrives at port that the it is subject to import quotas.
  • Possible health, safety or other regulations which apply to the product to be imported.

One easy to avoid, but common problem encountered when importing is the failure to mark the product in compliance with country of origin regulations. To avoid this, contact the relevant customs agency of the nation where the merchandise will be imported to ensure the goods are in compliance. For example, custom laws in the US require each imported good be marked with the English name of the country of origin (eg China) as reasonably, indelibly, and permanently as the nature of the article permits. Furthermore, this marking must be visible to the ultimate purchaser of the product.

The tariff rate levied by customs must be paid before the importer can take possession of the goods. While tariff rates in countries like the US average around 5% for most products, they can be significantly higher for some goods, particularly those with higher labor content. Therefore, it is important to know the rate before product arrives at port.

Before the goods are shipped, ensure the packing regulations for the destination country have been adhered. For example, every box, bale or case may need to be numbered with the exact quantity in each.

Other regulations include the type of pallets that can be used.

Problems with customs clearance often center around paperwork. Different goods often require different types of documentation, but the three major types of documentation the shipper must prepare include the following:

1. A bill of lading: This document, issued by the carrier or shipper, is basically a receipt of the goods acknowledging that they have been received on the vessel for shipment. This document indicates the particular vessel on which the goods have been placed, the destination of the goods, and the terms for transporting the goods to their final destination.

2. A commercial invoice: This is used as a customs declaration by the entity that is exporting an item across international borders. This document is required by customs to determine the value of the goods to assess duties and taxes, and goods must be invoiced in a systematic manner.

3. Packing list: This document is an itemized detail of the merchandise in a particular shipment. A copy is usually attached to the outside of the shipping container or inside the container itself so the merchandise may be counted by the person opening it.

It is crucial to make sure these documents, and any others that may be needed for a particular shipment, are carefully completed and reviewed before the goods arrive.

To avoid excess storage fees, arrange for a freight forwarder or some other type of transporter to ship the goods to their final destination as soon as they have cleared customs.

Being aware of these points, as well working closely with customs and a customs broker, will make the importing process smoother and will reduce the possibility of unnecessary difficulty or expense.

Food and Tea in China

Chinese food is a very popular type of food among American's and has become a favorite to many. With this in mind, many people consider going to China to experience the food directly from China. The food alone in China makes China a top travel destination. However, it is to be of no surprise that the Chinese food in China is very different from the Americanized Chinese food available within the United States.

The quality of rice available in China is much different than anywhere else across the globe. China has an abundance of rice fields, making rice readily available within the country. Rice is one of the main dishes in any Chinese meal.

There are several different locations in China to visit for various dishes you might like to try. Beijing is well-known for their Peking duck. However, Shanghai is famous for their pork buns. It is all dependent on what it is you are looking for as to what area of ​​China you would be pleased the most within your travels abroad to China.

However, some food customs in China are very different than anywhere an American traveler would be used to. In most parts of China, soups are served after the meal. However, the Cantonese do serve soup before the meal.

Aside from the Chinese food us Americans have grown to love China for, China is also famous for their tea. They are most famous for their jasmine and green tea. So, while in China, do not pass up the opportunity to taste their tea.

The Most Important Components of Physical Fitness

There are components of physical fitness which insurance companies and trainers take into account as they are significant to the overall evaluation of health. Basically it is similar to a fine-tuning a racing engine, you would never add diesel to an engine that requires high octane.

When physical trainers measure the fitness of a person they use some components of physical fitness to test against a set standard and to develop goals for further improvement. By incorporating these components of physical fitness you can not only improve your health but also lose weight.

The first of these is muscular strength. This measures the ability of the muscle to exert a maximal force through a range of motion or to a given point. This is measured for a short period of time and usually incorporates the use of weights for evaluation.

As muscular strength varies through the body, you might for instance you have
high muscular strength in your arms while having weaker legs, this component is related to the amount and type of exercise that your body undergoes. Weight training or strength training is the only method to improve strength. One principle of increased muscle mass is that that a larger amount of muscle consumes a greater number of calories, even at rest. By increasing mass you effectively increase the amount of calories needed for your body at rest and will reduce your body fat ratio. Another benefit to strength training is that it will help to maintain your bone structure and decrease your risk of osteoporosis.

The second component is muscular endurance. This reflects to your muscles ability to work through a range of motion over a specific amount of time. This can be measured by the ability to hold a weight for a specific amount of time – say 20 pounds over-head for 5 minutes. Many times this component is measured through push-ups as these are exercises that exert a specific amount of pressure over time. This measures the upper body muscular endurance.

Muscular endurance is often confused with muscular strength because they are related. However they offer different benefits, while using muscular endurance an athlete is able to shovel snow for an hour lifting and moving a sub-maximum amount of snow over a specified amount of time. Muscular strength would have been the ability of the arms and shoulders to lift the maximum amount a couple of times.

The trainer will test muscular endurance while he will also be testing cardiovascular endurance because these two components are closely related. Cardiovascular endurance will reflect how well your heart and lungs work together to supply oxygen to your body, this is also called aerobic fitness. Trainers may use long runs or swims to test cardiac endurance and test muscular endurance at the same time. This is the cornerstone to complete health and fitness. Without cardiovascular endurance you can not improve the rest of your fitness.

Another component is flexibility, this is the ability of a joint to move through its full range of motion and the elasticity of the muscles. Some refer to this as how limber or supple you are, this is a major component of physical fitness and one that is often over looked. Not everyone needs to be as limber as a gymnast but we all need a degree of flexibility to deal with the demands placed on us during our daily lives.

Stretching is associated with flexibility in order to maintain or increase the ability of a joint to stretch further. Maintaining your flexibility is important for protection of your joints and allowing you to strengthen further to protect your back and reduce the pain of arthritis.

The final component of physical fitness is body composition. This is the ratio of lean body mass to fat body mass. This proportion does not refer to your weight in pounds or to your figure but to a measurement against a standard. Women and men have different body composition ratios. Women carry a higher percentage of fat to maintain a developing baby. This does not mean that women are fatter – but that their fat distribution is different.

Your body composition is really more a consequence of your overall fitness. If you have a high body fat mass ratio you are more at risk for coronary heart disease, diabetes, joint and back pain, arthritis, stroke and tendon-muscle accidents.

These components of physical fitness are foundation to physical fitness and the ability of the human body to withstand external forces and internal stress while maintaining health and wellness.
