Alimak LSH Series
Alimak LSH Construction Hoist
The In-Shaft Specialist: Close Your Building Envelope Faster.
Stop leaving your exterior facade open just to accommodate a traditional hoist. The Alimak LSH is engineered to operate entirely inside the building’s permanent elevator shaft, allowing your teams to finish the exterior cladding months ahead of schedule while moving personnel safely inside.
Rethink High-Rise Logistics
Traditionally, construction hoists are anchored to the outside of the building. This creates a massive logistical headache: you cannot fully seal the building envelope (installing windows and exterior panels) until the exterior hoist is finally dismantled at the very end of the project.
The Alimak LSH completely eliminates this bottleneck. By utilizing the empty elevator shafts during the construction phase, this specialized rack-and-pinion hoist provides high-capacity vertical transport internally. It doubles your logistical efficiency compared to traditional wire-rope “jump lifts” and protects your workers and materials from the unpredictable Caribbean weather.
Engineered to Shorten Your Critical Path
1. Early Facade Closure
This is the ultimate financial advantage. Because the Alimak LSH runs inside the core of the building, your glazing and cladding contractors can seal the exterior facade continuously as the building rises. This allows interior finishing work (drywall, electrical, flooring) to begin much earlier in a climate-controlled environment.
2. Immune to Weather Delays
High winds and heavy rain frequently force exterior hoists to shut down for safety reasons, bringing your Caribbean job site to a standstill. Operating inside the concrete shaft, the LSH is 100% protected from the elements, ensuring uninterrupted vertical logistics 24/7.
3. Rack & Pinion Superiority (No Wire Ropes)
Unlike traditional traction “jump lifts” that require complex temporary machine rooms and vulnerable steel cables that stretch, the LSH uses Alimak’s proven rack and pinion drive. The motor travels with the car, making installation, operation, and mast extensions (“jumping”) significantly faster and safer.
4. Enhanced Site Safety
Operating within an enclosed shaft inherently reduces the risks associated with exterior high-altitude work. The LSH features precision floor leveling, robust door interlocks, and the standard Alimak overspeed safety device, providing a premium, secure ride for your crews.

Complex Internal Logistics, Handled Locally
Installing a hoist inside a tight concrete shaft requires precision engineering and an expert installation team.
Partnering with Bridge360 guarantees:
Pre-Construction Planning
Our engineers work directly with your architects to ensure the shaft dimensions and tie-in points are perfectly prepped for the LSH system before the concrete is even poured.
Rapid Turnaround
Dispatched from our DR hub, the equipment arrives on schedule to match your concrete slip-form or jump-form timeline.
Seamless Transition
Once your building is ready for the permanent commercial elevators, our crews quickly dismantle and remove the LSH, leaving the shaft perfectly clear for the final installation.
Take the Weather Out of the Equation
