Tips for Proper Equipment Transport

2/10/2022

Know your limits


Every situation will have unique securing procedures, but it is important to know the load rating of your trailer and the weight of your load. Load ratings are typically located on the trailer identification plate, and the weight of the load can be determined by using a certified scale.


Understand the law


The maximum legal load in the majority of states is 80,000 lb. Heavy or oversized loads will need specialized trailers and permits to legally transport. If you are unaware of the law in your state, or not certain of the requirements for your load, be sure to check with the local authorities before transporting your equipment.


Don't overload your trailer


It's best to use a trailer with a maximum capacity that is more than the weight of the load plus the weight of the trailer itself. If your load is close to the capacity for your trailer, use a heavier capacity trailer.


Always use properly rated tie downs


The Federal Motor Carrier Regulations determines the number of tie downs required based upon the weight of your load, as well as the tie down capacity. The basic requirement is that tie downs must have a combined strength equal to at least 50% of the load being secured.


Check your chains


Inspect tie downs and chains before each use, and discard any that have visual signs of wear or damage.


Distribute weight correctly


It is important to place loads so the weight is distributed evenly between the semi-tractor drive axles and the trailer axles. Too much weight on the front can make steering unresponsive, while excessive weight on the back can affect braking and decrease traction.


Don't damage equipment during tie down


Check the tie down points located on your load, and be sure to use them properly to avoid damage. 45˚ tie down angles offer the best protection and should keep your load from shifting or sliding.

Asphalt Compaction Tips

1/27/2022

Once your asphalt material is laid down, follow the best practices below to ensure it is compacted properly.


  • Mix Temperature – In general, the hotter the mix, the better the compaction result. However, the ideal rolling temperature varies based on a variety of factors, like mix composition, layer thickness, and the binding agent used.
  • Roller Passes – The best way to complete asphalt compaction is to start at the seams and then move along the edge of the pavement. In bends or turns, the compactor operator should compact the lane that has the smallest radius first and press down the pavement on the next pass. Dynamic compaction is used for subsequent passes with the whole operation completed by a final roller pass to remove any remaining imperfections.
  • Base Conditions – Base type and condition alter the level of compaction required in a new layer of asphalt. The amount of compaction needed depends on if the asphalt layer is on top of sub grade soil, aggregate base course, cold mix asphalt, cracked asphalt pavement, new asphalt concrete, or Portland cement concrete pavement. 
  • Environment – The temperature of the air and base, wind speed, and cloud cover all affect the cooling rate of the mix and the level of compaction required.

3 factors that affect your screed depth


  • Speed – The faster you travel the less your screed will rise up on the head of material, so you will need to increase your attachment angle. Similarly, if you are slowing down to make a turn or a tie in, the screed will ride up on the head of material more.
  • Mix – The asphalt you put through your spreader changes day to day and even truck to truck. It may have more aggregate, more liquid, or it may have sat longer. With this in mind, you always need to watch your depth and match height and make fine adjustments as needed.
  • Screed angle - The attachment angle on your screed controls the depth. When starting a new job for the first time, make sure you null out your screed on a flat surface. Once you set down on the mat for your first pull, then adjust your screed. It is typical for one turn of the screw to increase or decrease the material height by ½ inch.

Most common screed error: dropping the match height lower than the main screed


The match height adjusts the extension up or down in relation to the main screed. It needs to be adjusted in order to get the perfect mat. However, if you drop it lower than the main screed, you will get material starvation on your main screed. Soon after you will see shadowing or tearing behind your main screed and the screed will start to dive because it doesn't have any material to ride on.


To avoid this from happening, you should set the extension match height to the point where you start to see a small line coming off the corner of your main screed. Once you have that, you can leave it there, because this will typically roll out easily. However, if you want that perfect look, bump your match height down slightly to remove your line. Don't go too far, however, or you will have the same problem stated above.

How to sell your construction equipment 5 easy steps

5/24/2019

19 Comments

 
So you are ready to sell your construction equipment, heavy machine, tractor, etc. Maybe you want to buy something newer, or maybe you are ready to take a nice vacation, here are five easy steps that you should follow to make sure you get the most money. 
1. Find your machines value
​You can look at comparable machines on dealer sites and find what fits your machine best or you can use Pittman Tractor to help with your appraisal, just click here Free Equipment Appraisal
2. Decide how you want to sell ​
Need cash fast? Look at using a wholesaler, they will buy your machine quickly and give you a big check. Does your machine have low hours and in good shape? Auctions can give you a nice return, just watch out for seller fees; they can be up to 6% at some. Lastly, you want to get the most money and have plenty of time? Try listing it yourself, ebay and facebook are two easy options to sell your machine. 
3. Fix major issues ​
Does the machine run? Do the hydraulics work and do what it needs? Is it in good condition? If so you can skip this, but if you have hydraulic leaks, bad starter, final drive issues, worn our pads, etc. you may consider fixing these to get the most money for your machine. If not whole-selling to a dealer may be your best option. 
4. Give it a good cleaning ​
Ever been to a used car dealer where the cars were covered in dirt? I didn't think so; there is a reason everyone wants to buy something clean, so break out the soap, water, windex, and use your elbow grease. Cleaning will help set your machine above the rest even if you are whole-selling or sending it to an auction. 
5. Get Paid ​
​
Depending on which avenue you go will affect how quickly you make your money, but if you follow these steps, you will have yourself in the best position to make money.
