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?

Uses And Features Of Price Computing Scales

Price computing scales design all those scales that are normally available with an LCD display, but have an additional capability of converting units to price. As is evident for this description, price computing scales are useful for weighing by traders: fruits, vegetables, and other grocery items; meat and butcher shops; bakery items like cake and biscuits, ice cream sellers, hardware etc. A trader just needs to feed in the price per unit rate as many times as the market changes. Each time he will get readings for different items with their price. For the convenience of the customers Dual display LCD screens are also available with one in front for the counter attendant and the other at the back for the customer to see. Since most price computing scales are used in trade they are considered legal, if they have been approved by NTEP or any other regulatory body in your area.

The types of price computing scales vary according to features; you may be looking for 15 lb, 30 lb, or 60 lb. Capacity which can be calculated by one scale for fruits and vegetable weighing. Small sizes that save space and have a battery powered operation facilitating portability are also in demand as fruit sellers on carts or vendors need to move it from time to time. Deli shops, meat shops, candy counters or cheese shops with limited counter space may find compact design very useful.

Price computing scales is most desirable for the cost conscious retailer who wants to be honest in his dealings, since precision in weight reading and accuracy in price conversion is a matter of integrity for them. Electronic load cells with a digital display make sure that these shop owners are satisfied. Out of all scales available in the market the better ones are easy to install and operate with easy cleaning and minimum maintenance requirements. The more attractive ones have a rugged housing, sleek profile and small footprint with some additional features like

1. Raised keys with a key beeper

2. Battery operated with auto sleep and shut off options for power saving

3. High resolution to weigh small objects and give increments like 0.01 lb or 0.005 lb divisions

4. High grade polymer surface with stainless steel pan

5. Price computing function by count (number) of objects

6. Large memory storage up to 25 PLU's

7. Price accumulation at the end of grocery purchase by one customer.

8. Tare function to enable reset of display to zero after adding object each time to a loaded pan.

9. LCD displays with large numbers and back lit displays

Price computing scales like all others need to be bought with platform size and capacity in mind according to the type, size and weight of object you plan to put in it. Minimum and maximum weight requirements must be kept in mind to allow for your full range of products to be weighed by one scale. Finally accuracy in reading and durability of scales for use in harsh environments are factors that should drive the purchase decision.

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.
