What is the maximum rated carrying capacity and climbing height of the SMH 300V?

The SMH 300V twin mast multi-functional hoist is standard-rated to carry a maximum payload of 3.0 Tons (3000 kg) and is standard-engineered to climb safely up to a maximum vertical height of 150 meters at vertical speeds of 18 mtr/min. Its massive passenger-material cabin measures 2.0 x 3.5 x 3.0 meters to accommodate site workers alongside bulky construction aggregates comfortably.

How does the Twin Mast configuration benefit projects with massive or odd-sized materials?

Traditional single-cage hoists feature restricted cabin sizes that make carrying exceptionally long or bulky items (such as tower crane parts, heavy rebar cages, structural steel channels, large facade glasses, and large marble slabs) impossible. Spartan’s Twin Mast SMH 300V offers huge, customized platforms measuring 2.0 x 3.5 x 3.0 meters (and up to 6.0m length) to easily and safely transport bulk, oversized, and heavy B2B materials to high floors.

How do the quad European inline helical gear motors save up to 50% electrical power?

Traditional construction lifts use direct-drive motors that generate high friction and draw extreme current surges on startup. The SMH 300V is equipped with European-make inline helical bevel Rossi/Nord planetary design gearboxes driven by a synchronized 4-motor setup (5.5 kW x 4 Nos.). Pairing these gearboxes with our 30 kW Mitsubishi VFD minimizes rotational friction and starting current spikes, yielding up to 50% electrical power savings.

What automatic mechanical safety locks prevent the hoist cage from accidentally falling?

Personnel safety is Spartan's core manufacturing mandate. The SMH 300V is equipped with the advanced European-designed SSD 3500 progressive safety brake fitted on a separate plate in the carriage. In the rare event that descending speed exceeds safe travel boundaries (exceeding normal speed by 0.4 m/s or more), the centrifugal device activates a four-point contact lock to smoothly clamp the rack and arrest the cage. It is self-resetting, saving valuable on-site time.
