Challenger DX77-EXT Double Scissor Lift - 7,700 lb Capacity with Extended Ramps
Longer wheelbase vehicles on a standard scissor lift can be a headache. Wheels hanging off the edge of the platform, repositioning three times to get the pickup centered, losing time on every ticket. The Challenger DX77-EXT surface mount double scissor lift solves that problem with reinforced diamond-plate ramps that flip up and lock into place, extending the load length so full-size trucks, SUVs, and longer sedans sit squarely on the platforms without compromise.
At 7,700 lb capacity, this lift handles the full range of passenger vehicles rolling through your bays. The double scissor design delivers a 74.5" rise height on a surface mount installation, giving you real working clearance underneath without eating up ceiling space the way a two-post would. A synchronized hydraulic system keeps both platforms level through the full stroke, and the cross-member-free design means you've got open access all the way around and between the platforms. No tripping over structural bars, no awkward tool angles.
Productivity details matter here too. A single-point air-actuated lock release lets you set your working height without bending down to pull manual locks, and the power unit console keeps controls simple with three push buttons. Rise time is 43 seconds. The DX77-EXT is ALI/ETL certified and finished in a durable black powder coat that holds up in a working shop environment. If you need a flush mount option, Challenger offers the DX77R configuration with a 70" rise height for shops that prefer a drive-over-flush installation.

Installation and Setup
The DX77-EXT can be mounted above ground (surface mount) or flush with your shop floor. Surface mount installation delivers the full 74.5" rise height with a 4.5" lowered profile. Flush mount drops the rise to 70" but gives you a clean, drive-over surface when the lift is down. Your shop's floor condition and workflow will determine which approach fits best.
On the electrical side, you'll need a 208/220V single-phase circuit for the 2 HP motor. The air-actuated lock release system requires a compressed air supply between 90 and 120 PSI, so confirm your compressor can maintain that range under load before scheduling the install. Concrete thickness and condition should meet Challenger's published requirements for scissor lift anchoring.
Applications
High-volume service lanes processing a mix of sedans, SUVs, and full-size trucks benefit from the extended ramp design. You're not swapping lifts or repositioning vehicles for longer wheelbases.
A 43-second rise time and single-point lock release keep your ticket times tight. The open, cross-member-free work area speeds up oil changes, inspections, and undercar services.
With 7,700 lb capacity and 74.5" of rise, you've got the clearance and payload for brake work, exhaust, suspension, and drivetrain jobs across most passenger vehicles.
Full access around and between platforms means your techs can reach all four corners without fighting structural cross-members. The extended ramps make positioning longer vehicles quick and precise.
Shipping
Our team coordinates the freight shipment and helps manage scheduling details. The DX77-EXT ships via flatbed freight truck, and you'll need a forklift or similar equipment (tractor, skid steer) on-site to unload. Lift gate service is not available due to the weight of the unit. Deliveries arrive on a 48-foot semi, so make sure your location can accommodate that size vehicle.
If you don't have unloading equipment at your shop, shipment can be routed to a local freight terminal for pickup. You're responsible for coordinating the delivery appointment with the freight company. Lead times are subject to factory and warehouse stock availability.

Warranty
Challenger Lifts provides a limited warranty to the original purchaser covering repair or replacement of defective parts, including reasonable labor and transportation costs. The lift must be installed, used, and maintained according to Challenger's official specifications to qualify.
Coverage applies to lifts installed within the United States and Canada and is not transferable. Exclusions include consumable items, normal wear and tear, damage from misuse or improper installation, and repairs performed by unauthorized service representatives. Use of unapproved parts or accessories also voids coverage.
Warranty registration may be required after purchase. Refer to included documentation for details.

Frequently Asked Questions
What's the difference between the DX77 standard mount and the DX77R flush mount?
The standard surface mount DX77 delivers a 74.5" rise height with a 4.5" lowered profile and an 82" overall width. The flush mount DX77R sits level with your shop floor when lowered, provides a 70" rise height, and has a narrower 69.5" overall width. Your choice depends on whether you prefer a drive-over-flush layout or the additional rise height of a surface mount installation.
Can this lift handle full-size trucks and SUVs?
Yes. The DX77-EXT has a 7,700 lb total capacity (3,850 lb per platform) and features reinforced diamond-plate ramps that flip up and lock to extend the platform load length. This extended ramp design specifically accommodates longer wheelbase vehicles like full-size pickups, SUVs, and extended-cab trucks within the rated capacity.
What electrical and air requirements does the DX77-EXT need?
You'll need a 208/220V single-phase, 60 Hz circuit for the 2 HP motor. The air-actuated lock release system requires a shop air supply between 90 and 120 PSI. Confirm your compressor can sustain that pressure range under load before installation.
How fast does the lift reach full height?
The DX77-EXT reaches its full 74.5" rise height in 43 seconds. The synchronized hydraulic system keeps both platforms level throughout the entire lifting stroke, so you're not waiting on uneven platform movement or manual leveling adjustments.
Is the DX77-EXT ALI certified?
Yes. The Challenger DX77-EXT carries both ALI and ETL certification, confirming it meets the safety and performance standards established by the Automotive Lift Institute. This is a key checkpoint for shops that need to meet insurance or compliance requirements.
What do I need to unload the lift when it arrives?
You'll need a forklift, tractor, skid steer, or similar machinery to unload the lift from the flatbed truck. The driver does not assist with unloading. If you don't have equipment on-site, the freight can be routed to a local terminal for pickup with appropriate machinery.
Does this lift come with spotting blocks?
Yes. The DX77-EXT ships with two sets of rubber spotting blocks: a set of four 3" blocks and a set of four 1.5" blocks. These let you fine-tune contact points for different vehicle lift point configurations without purchasing additional adapters.
What kind of access do techs get around the vehicle?
The DX77-EXT uses a cross-member-free design, which means there are no structural bars running between the two platforms. Techs have unobstructed access all the way around the lifted vehicle and between both platforms, making undercar work, exhaust jobs, and drivetrain access significantly easier.
Is the warranty transferable if I sell my shop?
No. Challenger's limited warranty applies to the original purchaser only and is not transferable. The lift must be installed within the United States or Canada, and warranty registration may be required after purchase. Refer to the included documentation for registration details.
Can I use this lift for alignment work?
The DX77-EXT is a general service scissor lift and works well for undercar repairs, inspections, and maintenance. For dedicated alignment work, you'd typically pair a scissor lift with alignment-specific accessories like turnplates and slip plates. Contact us to discuss whether the DX77-EXT fits your alignment workflow at 7,700 lb capacity and 74.5" rise.
