How does the Electric Ox® get such long run times?
|
|
The drive system of the Electric Ox® is designed for both power and
efficiency. By using an independent motor and gearbox for each drive wheel,
power is used efficiently without the significant energy loss associated
with a traditional transmission. The sophisticated electronics at the
heart of the Electric Ox® meter power exactly as required with no
wastage. In fact, every time the Electric Ox® slows down or brakes,
the motors are turned into generators and deliver a charge back into the
batteries, further extending the running time. The efficiency of the drive
system allows the Electric Ox® to use standard lead acid batteries
and still deliver exceptionally long runtimes on a charge. |

What is an electronic differential and why do you use it?
|
|
With an electronic differential, there is no mechanical link between the
drive wheels. The power is applied to each wheel separately by the speed
controller. In a turn, the speed controller will apply less power to the
inner wheel. This provides a light steering feel and a smaller turning
radius than is possible with a traditional differential. In addition,
an electronic differential simulates a differential lock while front wheels
are driving straight. This means power is applied equally to both rear
wheels. Practically, this means that the Electric Ox® can pull more
weight in more adverse conditions. |

I don't see "brakes" as a standard feature. How can
that be? |
|
The Electric Ox® does not have a traditional braking system. To stop
the tractor, just release the accelerator pedal. The electric motors are
used to stop the vehicle. In fact, every time you stop the Electric Ox®,
the "brakes" recharge the battery. This "regenerative"
braking action is very powerful and you will find that even with a load,
the braking action is more than adequate. Once the vehicle is stopped,
an automatic parking brake comes on to prevent the Electric Ox® from
rolling. Regenerative braking is "maintenance free" as all traditional
mechanical brake components have been eliminated. |

|
The drawbar pull is rated at 700 lbs. but you say the Electric
Ox® can pull up to 8000 lbs. How can that be? |
|
The drawbar pull relates to the amount of force which can be exerted on
a stationary object. How much this force will pull depends on the rolling
resistance of the load. In ideal conditions, we have actually seen the
Electric Ox® pull up to 8000 lbs. In less than ideal conditions, it
will pull less. The following factors all contribute to how much actual
weight the Electric Ox® can pull: weight of the load, number of carts,
type of cart wheels, type of floor surface, degree of slope of the floor
surface, traction conditions, straight pull or a pull with angles and
curves, the length or duration of the pull and the speed of the pull.

Why do you offer both a 36 and 48 Volt version?
|
|
The 48 Volt version has more power, more speed and more run time in some
applications. It is also more expensive and is available with a 1500 watt
AC Inverter. As a result, we offer the 36 Volt version for customers who
do not need the added capabilities of the 48 volt unit. |
|
|
What is the difference between the Electric Ox® and the Electric
Ox® - MP? |
|
The only real difference is that the Electric Ox® - MP has an electric
lift system and is capable of accepting attachments. An Electric Ox®
towing vehicle cannot accept attachments and cannot be upgraded to do
so at a later date. |
