HEAVY-DUTY RACK & PINION SITE MOBILITY
High-Rise Construction Service Lifts & Builder Hoists
Engineered for fast, reliable vertical transit of site engineers, construction workers, concrete, structural steel, and building materials across high-rise residential towers, commercial developments, and industrial plant retrofits.
Precision Gear Meshing
High-tensile steel pinions meshed to machined mast racks, powered by dual/triple energy-efficient helical gear motors for smooth start-stop operation.
Twin Independent Cages
Run two separate cages on a single mast tower simultaneously to double material and personnel handling capacity without doubling mast installation costs.
Automatic Fall Arrester
Centrifugal progressive safety brake instantly clamps the mast column and halts cage descent smoothly within 0.15–0.25 seconds if over-speed occurs.
Up to 300+ Meters Height
Modular hot-dip galvanized steel mast sections with heavy-duty structural wall tie-in brackets engineered to withstand high coastal and monsoon wind loads.

MODULAR SITE CONFIGURATIONS
Cage Enclosures & Landing Gate Options
Engineered with high-visibility steel mesh, heavy-duty vehicle loading ramps, and fail-safe floor interlock barriers.
SITE EFFICIENCY
Twin Cage on Single Mast
Modular mast tower design allows adding a second independent passenger/material hoist basket as project construction height expands.
FAST WHEELBARROW ACCESS
Integrated Mechanical Ramps
Counterbalanced drop-down front and side loading ramps allowing smooth roll-in/roll-out transit for wheelbarrows, mortar tubs, and pallet trucks.
ZERO-FALL COMPLIANCE
Full-Height Landing Gates
Floor landing gates with electromechanical interlocks that only open when the hoist cage is securely docked at the specific floor level.
