Commercial Elevator Service: Hydraulic, Freight & MRL Systems

Service & Maintenance for Commercial, Freight & MRL Elevators

With over three decades of comprehensive elevator service expertise, Keystone Elevator delivers expert maintenance, repair, and modernization solutions for all major commercial elevator systems. Our certified technicians specialize in servicing hydraulic elevator systems, heavy-duty freight elevators, and advanced Machine Room-Less (MRL) installations. From routine maintenance and detailed inspections to emergency repairs and complete system modernization, we ensure your vertical transportation systems operate at peak performance and safety. Our preventive maintenance programs are tailored to each elevator type, helping building owners and property managers maintain reliable operation while maximizing their equipment's lifespan.

Designed for durability and heavy loads, freight elevators are essential for commercial and industrial buildings. These robust systems safely transport goods, equipment, and materials between floors while meeting strict safety and capacity requirements.

Freight Elevators

  • Typical height: Variable (depends on building)

  • Speed: 100-350 fpm

  • Load capacity: 4,000-20,000 lbs (some can handle more)

  • Door types: Vertical bi-parting or horizontal sliding

  • Platform sizes: Often 7-12 feet wide, 10-16 feet deep

  • Extra features: Heavy-duty flooring, bump rails, high ceilings

Representing the latest in elevator technology, MRL systems eliminate the need for a traditional machine room by incorporating compact equipment within the hoistway. These space-saving solutions deliver excellent energy efficiency and performance for modern buildings.

Machine Room-Less (MRL) Elevators

  • Typical height: 2-30 floors

  • Speed: 150-500 fpm

  • Load capacity: 2,000-5,000 lbs

  • Best for: Mid-rise buildings

  • Key advantage: No machine room needed, energy efficient

  • Space-saving design: Equipment fits within hoistway

Why Keystone Elevator

Your Trusted Partner for all your Elevator Needs

Our certified technicians are trained to work on all elevator types and bring decades of combined experience to every project. We understand the unique requirements and maintenance needs of each system:
•    Freight Elevators: Regular maintenance to handle heavy loads and industrial use
•    Hydraulic Systems: Fluid level monitoring and cylinder maintenance
•    MRL Elevators: Advanced diagnostic capabilities and modern control system expertise

The most common type of elevator in low to mid-rise buildings, hydraulic elevators offer reliable performance and cost-effective operation. These systems use fluid-driven pistons to provide smooth, consistent vertical transportation for passengers and light freight.

Hydraulic Elevators

  • Typical height: 2-8 floors (up to ~60-70 feet)

  • Speed: 100-150 feet per minute (fpm)

  • Load capacity: 2,500-5,000 lbs

  • Best for: Low to mid-rise buildings

  • Key advantage: Lower initial cost

  • Limitation: Higher energy consumption, limited height
