Challenger DX77 Flush Mount Scissor Lift 7700 lb Capacity

• 7,700 lb lifting capacity with 3,850 lb max per platform
• 70" rise height for comfortable working clearance
• Flush mount installation preserves shop floor aesthetics
• Cross-member-free design for unrestricted vehicle access
• ALI certified for safety and performance standards

Cross-Member-Free Design

The DX77R's open platform configuration eliminates obstructions between the lifting surfaces, providing technicians with unrestricted access all around the lifted vehicle. This clutter-free workspace increases efficiency and minimizes potential hazards during service operations.

Flush Mount Installation

Designed to be installed flush with your shop floor, the DX77R maximizes workspace and preserves the professional aesthetics of your facility. When lowered, vehicles can drive directly over the platforms without obstruction, optimizing traffic flow in busy service environments.

Double Scissor Lifting Mechanism

The dual scissor design delivers a 70" rise height while maintaining stability throughout the lifting cycle. This taller rise provides generous working clearance for technicians of all heights, reducing strain and improving productivity during extended service operations.

Synchronized Hydraulic System

Precision-engineered hydraulics ensure balanced, synchronized lifting across both platforms. The system maintains level operation throughout the entire rise cycle, providing stable and secure vehicle positioning for safe service work.

Reinforced Diamond-Plate Ramps

Heavy-duty front and rear access ramps feature a diamond-plate surface for superior traction. The ramps flip up and lock to extend the platform load length, accommodating longer wheelbase vehicles with ease.

Single Point Air Actuated Lock Release

The ergonomic lock release system operates at a comfortable working height, allowing technicians to increase productivity and minimize fatigue. The three-button control console provides simple, intuitive operation for raising, lowering, and lock release functions.

• Express Service Centers: The flush mount design and rapid 43-second rise time make the DX77R ideal for high-volume quick lube, tire, and maintenance operations where vehicle throughput is critical.
• Body Shops: Cross-member-free access provides unobstructed workspace for body repair, paint preparation, and undercarriage inspection without interference from lift components.
• Narrow Bay Applications: With an overall width of just 69.5", the DX77R fits comfortably in space-constrained service bays where traditional lifts may not be practical.
• Dealership Service Departments: The professional flush mount appearance maintains showroom-quality aesthetics while delivering the heavy-duty performance dealerships require.
• General Repair Shops: The 7,700 lb capacity handles a wide range of passenger vehicles, light trucks, and SUVs, making this lift versatile for diverse repair operations.

Electrical Requirements

Power: 208-240 VAC, single phase, 60Hz with a dedicated 30 Amp double-pole breaker or time delay fuse. A service disconnect switch must be installed near the point of operation. A licensed electrician must install and verify the electrical supply in compliance with all local electrical codes.

Concrete Foundation

Minimum Requirements: 4" thick reinforced concrete, 3500 psi minimum, cured for 28 days per local commercial practice. Floor must be level within 3/8" over the installation area. No anchors should be installed within 8" of any crack, edge, or expansion joint. The floor should be in good condition with no large cracks, spalling, or deterioration.

Flush Mount Pit Requirements

Pit Kit Required: The DX77R requires the Flush Mount Kit (Part# DX77-FM) which must be in place prior to pouring concrete. The kit contains frame components with concrete ties that must be positioned during the concrete pour. Contact Challenger Lifts for pit specifications and assistance before beginning concrete work.

Space Requirements

Minimum Bay Width: 12' minimum (12' recommended). Recommended Bay Length: 28'. Adequate vertical clearance must be calculated based on the full raised height of the lift plus the maximum vehicle height being serviced.

Professional Installation

Professional installation by qualified personnel is strongly recommended. The lift must be correctly installed and adjusted as described in the installation manual before attempting to raise any vehicle. Improper installation may void the warranty and could result in property damage or personal injury.
