In contrast, the design of tandem truck parking does not imply two parking spots with the second blocking the first. It simply means parking for tandem trucks.
A good example of tandem truck parking lots are the tandem truck parking lots in Massachusetts.
The state has several special parking lots for tandem trailer trucks.
The tandem truck parking lots include Springfield, Millbury, and Weston parking lots.
All these parking lots include special parking spaces for more than 15 trucks each.
How to Adjust or Slide Tandems on a Big Truck
To legally and safely haul a heavy load, it is important to position the axles of your truck properly.
Most semi-trucks on American roads have adjustable tandem axles.
In case a truck with adjustable tandem axles is loaded with cargo and the cargo is not balanced, the truck’s axles can be slid /adjusted to balance the cargo and ensure safe hauling of said cargo over a short or long distance.
The adjusting of adjustable tandem axles can help to balance the load between the trailer and truck axles.
It can also help to improve turning and control. Below are the most important steps you need to follow to adjust your truck’s tandem axles.
Step 1: Ensure your trailer and your semi-truck are coupled properly.
Step 2: Get into the semi-truck and switch on the ignition and leave it running.
Set the gear in neutral and then engage only the brakes of the semi-truck.
Step 3: Find the locking lever on the trailer’s side on top of the semi-truck’s rear wheels.
Engage the lever to release it. Make sure you slide it to completely release the locking pins. Make sure all the pins are properly disengaged.
Step 4: Get into the semi-truck and set the brakes of your trailer by engaging the trailer brake valve.
After doing this, release your truck’s brakes through pressing the yellow parking brake valve.
By setting the brakes of your trailer, you will prevent its wheels from moving.
This will allow you to push or pull the trailer on the slide to make the adjustments you need.
Step 5: To slide the tandems back, move the truck very slowly forward to reach the position you desire.
To slide the tandems forward, reverse the truck very slowly until you reach the position you desire.
Step 6: Get back into the truck and set its brakes again and then go to the trailer.
Put the locking lever back in the locked position and get back into the truck.
Step 7: Release the truck’s brakes only and reverse the trailer just slightly to set the locking pins.
You will hear the pins locking in place. When you are done set the truck’s brakes to inspect the locking pins.
If the pins are properly set in the tandems, you are nearly there.
Step 8: Inspect the locking lever to ensure it is properly locked and secured.
If it is, your truck’s tandems are adjusted and you are good to go.
Super Dump vs Tandem Dump Truck
The tandem dump truck can haul a maximum of thirteen tons each trip. It is a powerful truck used in carrying construction materials and so on.
In contrast, the super dump truck can haul twice this amount of weight (twenty-six tons) per trip.
This means if you want to do tandem dump truck work twice as fast, you use a super dump truck.
The only real advantage tandem dump trucks have over super dump trucks is that they are cheaper. Other than this, super dumps are perfect for big projects and for hauling big payloads each trip.
This is why they are used for big road construction projects and for mining.
Tandem Dump Trucks For Sale – Should You Rent, Lease or Buy?
You should rent a tandem dump truck if you want one to use for a couple of days or a couple of weeks.
This is because renting a tandem truck is cheaper than leasing or buying one if you want it for short term use.
You should lease a tandem truck if you want one to use for two or more years.
Leasing a tandem truck is better than buying one because it is cheaper and because maintenance costs will be taken care of by the leasing company or its agents.
Rarely is it a good idea to buy a tandem dump truck unless you find one very cheap or you run a massive corporation that can handle the cost.
This is because the total cost of ownership is often higher than the cost of leasing or renting.

A tandem trailer is a two rear axle trailer. The typical two rear axle trailer can carry up to 17 tons. This is, of course, not the official capacity of tandem trucks. Some of them have a lower weight-carrying capacity.
Where should my tandems be when empty?
They should be at the California 40’ mark. This is the safest length for them to be at. The California 40 feet mark is the center of the rear axle.
It is the law for tandems to be at this mark when empty. It is also the law for tandem axles not to exceed 34,000 per pair of rear axles.
