Challenger 7,700 lb Scissor Lift — Surface or Flush Mount
A shop planning a new scissor lift install often has to make a call before the equipment even arrives: pour a recessed pit and flush-mount for a clean, tripping-hazard-free floor, or surface-mount on the existing slab to save on concrete work. Most scissor lifts force a shop into one or the other before purchase. The Challenger DX77-SURF/FLUSH doesn't.
The DX77 is a 7,700 lb double scissor lift with standard-length ramps that installs either surface-mounted or flush-mounted — the same lift, the shop's choice at install time. That flexibility is what separates it from the DX77-EXT, which is flush-mount only and trades some rise height for an extended, low-approach-angle ramp built around scrape-prone vehicles. The standard DX77 rises to 74.5" (4.5" taller than the EXT's 70"), giving a bit more underbody working height, and its cross-member-free platform design keeps the area around and between the platforms clear on all sides.
Who the DX77-SURF/FLUSH Is Built For
- A shop that hasn't decided between surface and flush mount yet, and wants a lift that works either way rather than locking in a mount type before construction.
- An operation retrofitting an existing bay where pouring a full recessed pit isn't in the budget, but a clean flush finish is still preferred if feasible.
- A general-service shop that doesn't regularly see low-profile or scrape-prone vehicles and doesn't need the DX77-EXT's extended ramp geometry.
- A shop that wants the extra 4.5" of rise height (74.5" vs. 70") for slightly more underbody clearance on taller service jobs.
- A facility that values unobstructed access all around the lifted vehicle, thanks to the cross-member-free platform design.
- A shop standardizing on one scissor lift spec across multiple bays where some will be surface-mounted and others flush-mounted.
What the DX77-SURF/FLUSH Is NOT Built For
If your shop regularly services low-profile or lowered vehicles that scrape on approach, the DX77-EXT's extended ramp geometry solves that specific problem better than the standard-length ramps here. And if the job is alignment work rather than general service, the SX14 scissor alignment lift is purpose-built for that with runway synchronization the DX77 doesn't provide.
What Makes the DX77-SURF/FLUSH Different
Choice of Surface or Flush Mount
The DX77 installs on your existing slab as a surface-mounted lift, or recesses into a pit for a flush, floor-level finish — it's the same lift either way, and the decision is made at install time based on your bay and budget, not locked in before you buy. That flexibility is the defining difference between this model and the flush-only DX77-EXT.
Slightly Taller Rise (74.5")
At 74.5" of rise, the standard DX77 reaches 4.5" higher than the flush-only EXT variant's 70". For techs doing underbody work that benefits from extra standing clearance, that additional height adds up over a full day of service.
Double Scissor Design
The double scissor mechanism provides more overall working clearance underneath the vehicle than a single-scissor lift design at the same capacity — more room for the tech to move, not just lift height.
Cross-Member-Free Design
With no cross-member obstruction underneath, techs get free access all around the lifted vehicle and between the platforms. That open layout reduces trip hazards and makes it easier to work a job from any angle instead of navigating around lift hardware.
Includes Spotting Blocks
The DX77 ships with 3" and 1.5" rubber spotting block sets (4 each) already included, covering standard lift-point work without a separate purchase before the lift goes into service.
