FEATURES

Key Features

01. High-Safety Space-Optimized Site Logistics

Narrow Duct & Shaft Feasibility

Compact cabin dimensions (1.5m x 1.2m x 2.2m), combined with tight square mast profiles, make the SPM Series exceptionally well-suited for internal installations inside structural elevator shafts, narrow closed ducts, pylon bridge towers, and restricted layouts.

99% Unobstructed Free Space

Built with a specialized full-through cage design that leaves 99% of the interior volume completely free from structural brackets or internal mechanisms, ensuring maximum loading capacity.

Carries Big and Odd-Sized Material

Features a unique Top Open Roof design that allows site operators to transport exceptionally long and odd-sized structural components (such as scaffolding tubes, piping, door frames, and glass slabs) vertically. It also allows erection crews to add mast sections safely from inside the cage, avoiding high-fall hazards.

Standard Wall Tie Anchoring

Robust telescopic wall-tie structures provide exceptional stability to the mast column, supporting the vertical frame at tight 3-meter intervals.

02. High-Efficiency Helical Powertrain & VFD Control

European Inline Helical Bevel Gearbox

Driven by a premium European-make inline helical bevel geared motor configuration (5.19 kW x 2 Nos., totaling 10.38 kW of drive capacity). Minimizing mechanical rotational friction, planetary gearboxes achieve up to 50% electrical power savings.

Japanese Mitsubishi VFD Speed Controls

Outfitted standard with a premium Japanese-make Mitsubishi Variable Frequency Drive (VFD). The VFD regulates starting current spikes, prevents motor winding burnouts, and guarantees soft-starts and smooth deceleration to eliminate cabin jerking and vibration.

SMPS Control Voltage Safety

Onboard electrical controls operate on a stable 24 Volt DC supply converted via a protective Switched Mode Power Supply (SMPS) unit. This protects expensive electronic relays and display screens from severe site voltage drops or fluctuations.

Disciplined Wire Connections

All electrical wiring connections are tightly bound using heavy-duty cable ties and moisture-proof glands to withstand extreme outdoor environments and concrete splashes.

03. European CE-Certified Safety Systems

CE Safety Conformance

Engineered and manufactured in strict compliance with European safety standards EN12159:2012 and EN60204-1:2006+A1:2009, ensuring the structural framework and electrical grid remain sustainable under continuous maximum loads.

SAJ 20 Centrifugal Safety Brake

Mounted on a separate plate in the carriage, this advanced progressive safety device is centrifugally actuated. If traveling descent speed exceeds safe travel boundaries by 0.4 m/s or more, the SAJ 20 instantly clamps the square mast rack to smoothly arrest the cage. It is self-resetting on-site without requiring manual disassembly.

IP67 Teknic/Telemecanique Limit Switches

Incorporates top-tier limit switches (top, bottom, slow down, and final) with IP67 water- and dust-proof protection to prevent mechanical over-travel.

Electrical Entry Door Safety Switch

An electrical interlock safety switch prevents the entry doors from being opened while the cage is traveling. The hoist cannot move unless the cage doors are fully locked.

Mechanical Carriage Lock

Outfitted with an additional mechanical carriage lock to provide absolute safety for personnel during mast additions, height extensions, and routine maintenance.

04. Smart Cloud Telemetry & Operations

Industrial IoT Real-Time Telemetry

Fully integrated with Spartan's smart Industrial IoT platform. Site managers and OEM technical support teams can remotely monitor run hours, active power supply parameters, drop test counts, and fault histories displayed as analytical charts from an online dashboard.

Electrically Operated Mast Erection Jib

Outfitted with an integrated electric mast jib. The top frame can rotate 360° through bearings to insert mast sections at required locations easily and effortlessly, reducing physical worker efforts during erection.

What is the maximum rated carrying capacity and climbing height of the SPM 80L?

The SPM 80L square tube mast hoist is standard-rated to carry a maximum payload of 0.8 Tons (800 kg). It is standard-engineered to climb safely up to a maximum vertical height of 80 meters at a lifting speed of 20 meters per minute. Its compact, ergonomic cabin measures 1.5 x 1.2 x 2.2 meters.

Can this hoist be installed inside narrow elevator lift shafts?

Yes. Due to its compact square tube mast layout (150 x 150 mm center-to-center), a tight cage footprint of 1.5m x 1.2m, and a highly compact foundation base requirement of only 2.0 x 2.2 x 0.25 meters, the SPM 80L is exceptionally well-suited for internal installations inside structural elevator shafts, narrow closed ducts, structural pylon bridge towers, or restricted building spaces.

How does the SAJ 20 progressive safety brake operate?

Worker and passenger safety is Spartan's core manufacturing mandate. The SPM 80L features the advanced SAJ 20 centrifugal safety brake fitted on a separate plate in the carriage. Conforming strictly to the EN12159 hoist standard, if the cage descending speed exceeds the normal travel boundary by 0.4 m/s or more, the centrifugal device automatically clamps the square mast rack to smoothly arrest the downward travel of the cage.

What are the performance benefits of European inline helical geared motors?

The SPM 80L is equipped with premium European-make inline helical bevel geared motors (5.19 kW x 2 nos.). This high-efficiency mechanical setup features IP55 protection for quiet, weatherproof operations. It provides smooth starting torque, prevents mechanical motor jerking, and delivers an extended gear/bearing lubrication life, drastically reducing your operational maintenance overheads.

What electrical safety systems protect our operators and control panel?

The SPM 80L control panel incorporates a Switched Mode Power Supply (SMPS) unit that converts electric power efficiently into safe 24 Volt DC, protecting expensive electronic relays and displays from site voltage drops. Additionally, it features high-reliability IP67 Teknic or Telemecanique limit switches to prevent over-travel, electrical entry door safety switches to halt travel if cabin doors are unlocked, and a mechanical carriage lock for additional safety during mast additions.

How can we monitor the machine's real-time performance and prevent unexpected breakdowns?

Every SPM 80L is fully integrated with Spartan's smart Industrial IoT platform. Site project managers and Spartan's OEM technical team can remotely monitor machine diagnostic data including total operating run hours, active power supply conditions, fault history logs, drop test counts, and lift halt positions displayed as analytical time-series charts directly from an online dashboard.
