CHOI-V / CHOI-MRL / CHOI-MRL-Pro Passenger Elevator Series (Small Machine Room / Machine Room-Less)
In-house designed and manufactured compact control cabinet for small machine rooms. By adopting advanced integrated circuit technology, it enhances anti-interference capability, reduces wiring complexity, and minimizes cabinet dimensions, thereby effectively optimizing machine room space utilization.
Standardly equipped with a upper beam diverter pulley damping device, complemented by 6-to-8 point cabin bottom vibration isolation and an anti-sway car top design to form a triple damping system. It comprehensively optimizes cabin vibration resistance for superior ride comfort.
Offers both machine-supporting beam and guide-rail-mounted drive options to easily accommodate diverse architectural shaft conditions. The thoroughly analyzed and tested mechanical drive structure ensures balanced load-bearing and damping distribution for smoother operation.
Dedicated split-type control cabinet developed in-house for MRL elevators. Its compact profile significantly reduces overall volume and minimizes landing door overhead clearance requirements, reducing civil engineering costs while delivering a sleek, harmonious aesthetic.
Proprietary MRL monitoring technology allows rescue personnel to intuitively observe elevator traveling direction, leveling status, and speed via the monitoring panel. This ensures precise cabin positioning during emergencies, substantially boosting rescue efficiency.
The cabin diverter pulley center, car center of gravity, and main guide rail center are precisely aligned on the same vertical axis, ensuring remarkably smooth travel and higher ride comfort.
Adopts silent contactor technology to dramatically reduce switching noise during every elevator start and stop cycle in machine-room-less installations.

Universally applicable for domestic and international machine-room-less projects; widely used in residential commodity housing developments; ideal for affordable housing initiatives and public welfare residential projects.
Ultra-slim permanent magnet synchronous traction machine is mounted on the back of the main guide rail, setting an industry-leading standard for overhead headroom reduction. Compact layout minimizes shaft footprint: shaft width ≤ car width + 550 mm.
Utilizes a lightweight chassis and steel support beams for straightforward installation. The low-profile traction machine placement and front-mounted magnetic ring encoder allow seamless commissioning and routine maintenance.
Under-slung cantilever beam layout achieves unified alignment of suspension center, center of gravity, and guide rail center, delivering ultra-smooth operation and a higher safety factor. It optimizes load distribution on guide rails, significantly reducing lateral guide shoe wear.
The machine base utilizes neoprene damping pads to effectively mitigate vibration transmission to the cabin, offering superior anti-aging resilience to extend service life. The upper section incorporates an annular damping sleeve to reliably suppress sway while maintaining a flexible connection between the machine and guide rails.
Delivers maintenance-free performance and reduced rolling friction. Combines spring mechanics with rubber or polyurethane for dual vibration damping, offering excellent tolerance to rail deviations and an ultra-quiet, plush ride.
Bolted guide rail brackets drastically reduce on-site welding and torch cutting. The bolted counterweight frame facilitates efficient mass production, shortens project lead times, and streamlines shipping and logistics.
