School Bus Lift
I ran across the picture above in my Facebook find and thought that this picture is worth a thousand words. If you take a look at the roof of the school bus, the instructors painted 5 steps for the students to follow. The picture was posted on the City of Turlock – Fire Department Facebook page from some training the had on their new Paratech rescue equipment.
Here are the steps:
- Identify the load (Type C or D School 30,000 Lbs)
- Stabilize the top vehicle
- Lower the bottom vehicle (Remove the air for the tires and/or capture the suspension)
- Lift the top vehicle
- Separate the vehicles/extricate/patient removal
So what do school buses weigh?
|School Bus Type||Gross Vehicle Weight Rating*|
|Type A1||GVWR of less than 10,000 lbs.|
|Type A2||GVWR of more than 10,000 lbs. A popular style Type A introduced in 2004 was rated at 14,000 lbs. GVWR.|
|Type B||GVWR of more than 10,000 lbs.|
|Type C||GVWR of more than 10,000 lbs. Type C school buses typically range between 23,500 lbs. to 29,500 lbs GVWR, depending on seating capacity.|
|Type D||GVWR of more than 10,000 lbs. Type D school buses typically range between 25,000 lbs. to 36,000 lbs. GVWR, depending on seating capacity.|
* Gross vehicle weight rating ( GVWR ) is the estimated total weight of a school bus that is loaded to capacity, including the weight of the vehicle itself plus fuel, passengers, and other miscellaneous items such as extra aftermarket parts.
Vehicle School Bus Under-ride Training Scenario

Zero-emission Electric School Bus
There are about 480,000 school buses in the United States with about 95 percent of them run on diesel. How many will change to electric?
Electric School Bus
There are about 480,000 school buses in the United States with about 95 percent of them run on diesel. Currently, electric buses can be about two to three times as expensive as diesel models. However, school administrators would ultimately save about $2,000 on fuel and $4,400 in maintenance every year. Many school districts across the United States are adding zero emission or hybrid school buses into their fleets.
States across the country are looking into using their legal settlement funds from Volkswagen defeat device settlement to buy electric school buses. Just like electric passenger a decade again were few and far between, electric school buses are sparsely found in school district’s fleets.
School Bus Types
Below is a quick review of the 4 different types of school buses used in the United States.
|School Bus Configurations
(Images of Contemporary School Bus Models)
|Configuration||Type A||Type B||Type C||Type D|
|≥10 typically 16-36||≥10 typically 30-36||≥10 typically 36-78||≥10 typically 54-90|
Type A Electric School Bus
Blue Bird offers electric Type C & D configuration school bus.
Propane School Bus
Green and blue bumpers and other surfaces on school buses can identify a school as electric powered. However, green is also used for school buses powered by Compressed Natural Gas (CNG) and Propane.
HydraFusion Struts used as ram for a dash roll?
The HydraFusion Struts were a game changer when PARATECH released the lifting/stabilizing device a few years back at FDIC. Rescuers can lift up to 10 U.S. Tons (9 metric tons) and to stabilize up to 20,000 lbs. with the tool. However, PARATECH’s HydraFusion Struts are not limited to just those two functions. The HydraFusion Struts can move metal!
I first ran across pictures of HydraFusion Struts used as ram from pictures that Brock Archer (Advanced Extrication) and Randy Schmitz ( Founder/Owner of Schmitz Mittz). Last weekend at Crunchtime Extrication, Paratech had one of their trailers at the training event and I had the chance to try a dash roll with a HydraFusion Strut. Take a look at the video below.
A few quick points:
- You can put the HydraFusion Strut in place to reduce any dash movement during reliefs cuts.
- HydraFusion Strut are portable and can be moved quickly to a vehicle hundreds of feet of the roadway.
- Depending on the length of the HydraFusion Strut used, strut extensions can be used to optimize dash movement.
- Using a HydraFusion Strut as a ram is an option, not always the option.
