Challenger Lifts DX77-FM Double Scissor Recessed Installation Kit for Flush Mount Lift Applications
The Challenger Lifts DX77-FM is the factory-engineered flush mount installation kit designed specifically for recessed installation of the Challenger DX77 dual scissor lift. This kit includes two precision-manufactured pit frames with integrated concrete ties that must be positioned before your concrete pour to create a seamless, floor-level lift installation. When combined with the DX77 lift (sold separately), the flush mount configuration delivers a 70" rise height while eliminating surface-mounted obstructions for improved shop traffic flow and a cleaner, more professional appearance.
Challenger DX77-FM Features
Precision-Engineered Pit Frames
The DX77-FM kit includes two heavy-duty pit frames manufactured to exact specifications for the DX77 dual scissor lift. Each frame is designed to provide a stable, level foundation that ensures proper lift operation and long-term durability in demanding shop environments.
Integrated Concrete Ties
Built-in concrete tie points secure the pit frames during the concrete pour, ensuring the frames remain perfectly positioned as the concrete cures. This integrated design eliminates the need for additional anchoring hardware during initial installation.
Flush Mount Advantage
Recessed installation places the lift platforms level with your shop floor when lowered, eliminating drive-over ramps and surface obstructions. This creates unobstructed traffic flow and a cleaner, more professional shop appearance while maintaining full lift functionality.
Optimized Rise Height
The flush mount configuration provides a 70" rise height from the floor surface, delivering comfortable working clearance for undercar service on passenger vehicles, light trucks, and SUVs without requiring additional pit depth.
Compatible with Wide Vehicle Configuration
The DX77-FM kit supports both standard and wide platform spacing configurations. Standard spacing of 21" to 27" between platforms accommodates most vehicles, while optional configurations support 36.8" spacing for wide electric vehicles and specialty applications.
American Engineering and Manufacturing
Designed and manufactured by Challenger Lifts in Louisville, Kentucky, the DX77-FM reflects decades of automotive lift expertise. Challenger's commitment to American manufacturing ensures consistent quality, readily available replacement parts, and responsive technical support.

Our equipment specialists can help with pit specifications, installation planning, and coordinating your complete DX77 flush mount lift system.
Challenger DX77-FM FAQ
Does this kit include the DX77 scissor lift?
No, the DX77-FM is the flush mount installation kit only. It includes two pit frames with concrete ties for recessed installation. The Challenger DX77 dual scissor lift must be purchased separately.
When do the pit frames need to be installed?
The pit frames must be positioned and secured before concrete is poured. They cannot be installed after the concrete floor is in place. The kit includes concrete ties to hold the frames in position during the pour. Temporary pit forms are not included and must be provided by the installer.
What are the concrete requirements for flush mount installation?
The concrete must be a minimum of 4" deep with steel reinforcement, rated at 3,500 PSI minimum, and cured for 28 days per local commercial practice. The floor must be level within 3/8" over the installation area, and no anchors should be installed within 8" of any crack, edge, or expansion joint.
What is the maximum distance from the pit to the control console?
The total pipe chase length from the pit to the bottom rear of the control console must not exceed 72". The standard hydraulic hoses only accommodate this distance. If you need to position the console further away, extended hoses can be sourced but must meet specific specifications: 1/4" minimum ID, 3,000 PSI working pressure, 12,000 PSI burst pressure with #6 JIC Swivel Female fittings.
What is the difference between flush mount and surface mount installation?
Flush mount (recessed) installation places the lift platforms level with the shop floor when lowered, creating a seamless surface with no obstructions. Surface mount installation positions the lift on top of the existing floor with drive-over ramps. Flush mount provides cleaner shop aesthetics and improved traffic flow but requires pit construction before concrete is poured.
What is the rise height with flush mount installation?
The flush mount configuration provides a 70" rise height from floor level. This compares to 74-1/2" rise height for surface mount installation, which includes the 4-1/2" lowered height of the platforms above the floor surface.
Can this kit be used for wide electric vehicle configurations?
Yes, the DX77 lift supports both standard platform spacing (21" to 27" between platforms) and wide spacing (36.8") for electric vehicles and specialty applications. For wide configurations, extended hydraulic hoses and air lines may be required to position the control console, and optional hose covers (Part# 10354-4) are available.
What electrical and air supply is required?
The DX77 lift requires 208/220 VAC, single phase, 60 Hz power with a dedicated 30 Amp double-pole circuit breaker or time delay fuse. Compressed air supply of 90-120 PSI (clean and dry) is required for the pneumatic lock release system. All electrical work must comply with local codes.
Is professional installation required?
While not strictly required, professional installation is strongly recommended due to the critical nature of pit frame positioning and concrete work. Improper installation can affect lift operation, safety, and may void warranty coverage. The concrete work should be performed by qualified contractors familiar with commercial floor specifications.
What is the lift capacity of the DX77?
The Challenger DX77 has a total lifting capacity of 7,700 lb (3,500 kg) with loads equally distributed, or 3,850 lb (1,750 kg) maximum per pad. The lift should never be operated with only one pad supporting a vehicle.
Are temporary pit forms included with this kit?
No, temporary pit forms are not included and are the responsibility of the installer. The kit includes the permanent pit frames with concrete ties, but the temporary forms used to create the pit shape during concrete pouring must be fabricated or sourced separately based on the pit specifications in the installation manual.
What maintenance is required for flush mount installations?
Flush mount installations require the same maintenance as surface mount: daily cleaning and inspection, weekly cleaning around the base, monthly anchor torque checks (40 ft-lb), lubrication of slide tracks with heavy viscous grease, greasing all pins, and checking platform synchronization. Keep the pit area clean and free of debris that could interfere with lift operation.
