Customer Background
A yacht owner in Sydney approached our local agent Tony for help with replacing an aging marine dumbwaiter. The original unit, a European brand, was experiencing frequent electrical failures and becoming unreliable. To control costs, the owner hoped to retain the existing shaft frame rather than replacing the full system.
Tony visited the yacht for an on-site assessment. He recorded all necessary shaft and door measurements and identified an important detail: the old motor was installed in a separate compartment, not directly above the car. This layout required a customized solution to ensure compatibility.
Requirements Overview
The project required a solution that was both cost-effective and technically adaptable.
Key requirements included:
- Reusing the existing shaft frame to avoid structural changes
- Adapting to the yacht’s special motor layout, with the motor housed separately
- Withstanding harsh marine conditions, including high humidity and salt exposure
- Ensuring reliable daily operation even while the yacht is in motion
- Measured dimensions:
- Shaft: 4520 mm (H) × 850 mm (D) × 770 mm (W)
- Door opening height: 700 mm (1F), 550 mm (2F)
- Door frame: 850 mm (H) × 800 mm (W)
- Motor compartment: 800 mm (W) × 600 mm (H)
Our Solution
Our technical team designed a customized marine dumbwaiter system specifically for yacht use, addressing the client’s layout and environmental challenges. The existing shaft frame was confirmed to be structurally sound and was reused. All components were selected and treated for corrosion resistance and marine durability.
Main features of the system include:
- Drive Unit
High-torque motor with a custom rope-retention mechanism to prevent detachment
Anti-vibration pads to reduce resonance caused by yacht movement
- Guide System
Solid T50 steel guide rails (3 rails for extra stability)
Custom rear guide shoes designed to stay secure during motion
- Corrosion-Resistant Materials
All wire ropes and fasteners (door, motor) made from 304 stainless steel
Car, landing doors, and door panels made from 304 stainless steel sheets
Car frame and gantry components treated with anti-rust primer and baked finish for durability
- Cable Management
Aluminum cable trays installed inside the shaft to protect wiring
- Production & Delivery:
The system was manufactured and tested within 15 days. For sea transport, each part was packed in individual reinforced wooden crates to ensure safety during shipping.
- Maintenance Tip:
Due to the yacht’s movement, we advised the client to use grease instead of oil cups for guide rail lubrication. This prevents leaks and keeps the surroundings clean.
Client Feedback
“Tony responded quickly and gave me a clear plan after the first visit. The dumbwaiter’s quality compares well with European brands, but the price was far more reasonable. From purchase to installation, everything was completed one month ahead of schedule. Very impressed with the efficiency and service.”
