Pulse Heavy-Duty All-Terrain Wheelchair: Pulse HeavyDuty & Pulse DualDrive

Not every power wheelchair needs to be as light as possible. For users who move across outdoor paths, kerbs and uneven ground every day, strength and stability matter more than saving a few kilograms. That is what the Pulse HeavyDuty and DualDrive are built for.

What are the Pulse HeavyDuty and DualDrive? The Pulse HeavyDuty and Pulse DualDrive are heavy-duty folding power wheelchairs with a steel frame that carries up to 140 kg. Both run on a 24V 20Ah lithium-ion battery for about 15 km per charge. Pulse DualDrive adds large 23-inch rear wheels that can also be pushed by hand.

Who Needs the Pulse HeavyDuty and DualDrive

The Pulse HeavyDuty and DualDrive suit users who:

Move across outdoor paths, gravel, kerbs or uneven ground often
Weigh up to 140 kg
Use a wheelchair all day, every day
Want a strong, stable chair more than the lightest one

If frequent air travel or lifting the chair into a car is the priority, compare Pulse's lighter Premium Comfort, TravelMate, Everyday or SmartFold instead.

Operating the Pulse HeavyDuty and DualDrive

Both models use joystick control, two 250 W motors (500 W in total) and electromagnetic brakes. They fold with an X-fold design, but being heavy-duty, they are bulkier than Pulse's light models. The roomy 44 x 44 cm seat suits long hours of sitting.

Pulse HeavyDuty or Pulse DualDrive?

Pulse HeavyDuty has 10-inch front and 16-inch rear wheels and weighs 36 kg without the battery. Pulse DualDrive weighs 31 kg and has large 23-inch rear wheels, so a carer or the user can also push it by hand if the battery runs low.

Key Facts at a Glance

Pulse HeavyDuty and Pulse DualDrive are heavy-duty, foldable power wheelchairs with joystick control.
Their 24V 20Ah lithium-ion battery stores about 480 Wh.
Top speed is 6 km/h.
WHO's 2023 Wheelchair Provision Guidelines recommend a personal assessment, proper fitting, user training and follow-up for every wheelchair user.

Flying with the Pulse HeavyDuty and DualDrive

Airlines care about how much energy a wheelchair battery stores, measured in watt-hours (Wh). You work it out as volts × amp-hours. The Pulse HeavyDuty and DualDrive use a 24V 20Ah lithium-ion battery, which is about 480 Wh. That is above the 300 Wh limit that airline safety rules set for a battery removed from a wheelchair. If the battery stays fitted in the chair there is no watt-hour limit, but you must get the airline's approval in advance.

Always tell your airline before you fly. Removed and spare batteries must go in the cabin with their terminals covered. You may carry one spare battery up to 300 Wh, or two spares up to 160 Wh each.
