Drive STSM450 Sit-to-Stand Power Lift – 450 lb Capacity
Drive Medical STSM450 Powered Sit-to-Stand Patient Lift — 450 lb Capacity
Heavy-Duty Powered Sit-to-Stand Elevation Architecture with 450 lb Capacity, Dual-Control Pendant & Mast Interface, Low 4.75″ Base Profile, Overload Protection, and Height-Adjustable Knee Support
The Drive Medical STSM450 Sit-to-Stand Lift is a heavy-duty, motorized patient transfer aid engineered to facilitate smooth, supported standing transitions for individuals who possess partial weight-bearing capability. Built with heavy-gauge steel construction to support user capacities up to 450 lbs, this powered lift assists patients during transfers between beds, armchairs, wheelchairs, and commodes while dramatically reducing physical strain for caregivers in home and institutional environments.
Designed for versatile access, the manual width-adjustable base narrows to 24.5 inches to pass through standard doorways and expands to 41.8 inches to maneuver around wide seating. Featuring a low 4.75-inch base profile with 2.7 inches of ground clearance, the STSM450 glides easily under low-profile medical beds. Operated via a redundant dual-control system—incorporating both a handheld pendant and a mast-mounted control box—the unit includes automatic obstruction stopping alongside audible and visual alerts for low battery status and weight overload for total caregiver confidence.
Key Features & Benefits
- Heavy-Duty 450 lb Support Capacity: Reinforced steel frame provides stable, reliable standing assistance for standard and bariatric users up to 450 lbs.
- Redundant Dual-Control System: Can be operated via the ergonomic hand pendant or directly from the mast-mounted control box, ensuring continuous operational capability.
- Integrated Safety Sensor Suite: Equipped with audible and visual indicators for low battery power and overload warnings, plus automatic stop mechanisms if obstacles are detected during operation.
- Low 4.75″ Base Height Clearance: Low-profile front chassis slides easily under low bed frames and furniture where thicker bases collide.
- Ergonomic Knee Pad & Footplate: Features a height-adjustable padded knee support and a removable non-skid footplate to ensure proper lower-body alignment.
- Versatile 4-Point Sling Cradle: Spreader bar hooks accommodate a wide variety of 2-hook and 4-hook sit-to-stand and transfer slings (slings sold separately).
- Manual Width-Adjustable Base: Spreads from 24.5″ closed to 41.8″ open to roll smoothly around wide armchairs, recliners, and wheelchairs.
Patient Handling Specialist Insight: The Drive STSM450 excels in both home and clinical environments thanks to its dual-control redundancy and ultra-low base clearance. Having control interfaces on both the hand pendant and the mast control box ensures caregivers never get stranded during a transfer if a remote wire is misplaced, while the low 4.75-inch frame height slides cleanly under low homecare bed frames.

Frequently Asked Questions
Which patients are suitable candidates for the Drive STSM450 lift?
The STSM450 is designed for patients who possess partial weight-bearing capacity in their legs and basic upper-body strength to hold onto the support handles during standing. Fully non-weight-bearing patients require a passive full-body Hoyer sling lift.
Are slings included with the STSM450 lift?
No, sit-to-stand slings are sold separately so caregivers can select the precise size, padding level, and head/back support configuration required for the user's specific physical needs.
How does the dual-control system benefit caregivers?
The dual-control architecture allows operation either through the tethered hand pendant or directly via buttons on the mast control box. This backup control option ensures the lift remains fully operational even if the hand pendant is damaged or unavailable.
