Overland Big Herc Powered Inflatable Hand Truck

The Big Herc Inflatable Hand Truck is the latest addition to our 950 Series.  At the heart of the Big Herc is our brand new 950W direct drive electric motor along with a 35 Amp Hr long lasting rechargeable battery pack.  The result is a cart that can haul up to 950 pounds and last through an entire work day.  We built this cart with direct input from inflatable companies who make their living moving bounce houses.  Overall it packs a serious punch of power.  The Big Herc also features industry specific features such as built in e-strap pockets and d-rings.  There are numerous advantages of electric power over gas powered such as; zero maintenance, quiet operation, ease of use, zero emissions, and indoor/outdoor capabilities.   All Overland Carts are built to professional grade standards and are backed by a 3 year limited warranty.  13” Flat free dual ag tires are standard.  Made in the USA. 

**Overland Carts ship fully assembled via Freight Carrier/Common Carrier**
**Lift Gate service is required for MOST residential customers as it lowers the product to the ground**

Safety Features

  • SmoothStart – On acceleration, power is applied to the drive tires in a controlled manner ensuring a smooth start each time.
  • HillSense – Allows the cart to be safely used on inclines and declines.  The cart will travel at the speed set by the user, not by the incline or decline.
  • AutoLock – An automatic parking brake locks the wheels when the throttle is not being applied.  This feature prevents the cart from rolling away from the user and also provides easy loading and unloading on inclines and declines.
  • Emergency Stop – The red E-Stop button allows the user to immediately stop the progress of the cart.
  • Four Wheel Design – All Overland Carts have at least four wheels to provide maximum stability.
  • Overload Fuse – There is a built in overload fuse that measures the inputs of the drive system in real time.  If the incline, load, or terrain begins to overwork the motor, a fuse will stop the cart and prevent any damage to the transaxle.
  • Throttle Controlled Braking – The braking is controlled by the throttle, simply let up on the throttle and the cart will slow down to the desired speed.  To brake is automatically applied.
  • Throttle Defaults to Zero MPH – If the throttle is released for any reason, the throttle will automatically return to the zero MPH position and the cart will safely coast to a stop.  AutoLock will then engage and the cart will be secure.
  • No open gears, belts, or hot components – The design of the cart keeps hands safe and prevents possible burns caused by hot engine components.
  • Tested Over Time – Overland Cart has been developing and building carts for 10 years.  We know our carts and have developed them to be as safe as possible.

Additional Features

  • Heavy Duty Steel Chassis – The oversized chassis is built on a frame of welded steel designed to support and carry the largest inflatables.
  • Easy Start – Simply pull out the red E-stop button on the handle and the cart is immediately ready to drive.
  • Variable Speed Twist Throttle – Similar to a motorcycle throttle.  Very easy to use and to control the speed.
  • Enclosed Gear Box – Gears are enclosed for maximum safety and durability.  The transaxle is sealed for life and does not require any maintenance.
  • Direct Drive Motor – The smoothest and most reliable form of electric power is direct drive.  No chains.
  • Manual Mode – Allows the cart to be operated without battery power.
  • Forward/Reverse – Direction can be selected from the toggle switch on the handlebar.  The cart travels the same speed in either direction.
  • Near Silent Operation – The electric drive system is almost silent in its operation.
  • IMPROVED Battery Life – 6-8 hours of run time on a standard battery.
  • 110V Off Board Smart Charger – Charge the cart with an extension cord or plug it right in the wall.  The smart charger design will ensure the battery is always charged safely and quickly.
  • Battery Life Indicator – LED lights ensure you always know the current battery status
  • Rechargeable AGM Sealed Lead Acid Batteries – Absorbent Glass Mat (AGM) batteries are the most advanced batteries on the market and offer a spill-proof design.
  • Removable Rechargeable Battery Pack – Quickly swap battery packs or remove the battery pack to charge it.
  • Powder Coated Frame – The chassis is welded and powder coated in house for lasting finish
