Food-Grade Stainless Steel Freight Elevator for Chocolate Manufacturing

Project Overview

Customized for a chocolate production facility, the SJD3-5 stainless steel freight elevator delivers 3-ton load capacity and 5-meter lift height.

Designed for food industry compliance, it features a hygienic structure, anti-slip platform, and 7-layer safety mechanisms (explosion-proof valves, emergency descent, etc.), enabling efficient transport of cocoa beans, sugar, and finished products without floor pit construction.

Basic Parameters

Feature	Specification
Model	SJD3-5
Platform Size	1800 × 2700mm
Footprint	2500 × 2800mm
Stops	2 floors / 2 stations
Lift Height	5000mm (No pit required)
Load Capacity	3000kg
Speed	4-6 m/min
Coating	Medium gray or blue (Anti-stain)
Installation	Indoor slab-cut mounting
Safety Features
	Emergency stop button
	Overload relief valve
	Safety wire rope (anti-fall)
	Diagonal balance cables (auto-leveling)
	Manual pressure release valve
	Phase-loss protection relay
	Cylinder anti-burst valve

The Challenge

High-Frequency Handling: Daily transport of 3-ton raw materials (cocoa, sugar) and products strained traditional elevators;
Hygiene Compliance: Required contamination-free, easy-to-clean equipment;
Space Constraints: Pit-free installation to avoid structural modifications;
Emergency Safety: Risks from power outages or hydraulic failures.

Solutions

HACCP-Compliant Design:
Pit-Free Installation: Direct slab integration reduces construction time;
7-Layer Protection:
- Dual anti-fall mechanisms (burst valve + wire rope);
- Phase-loss protection + manual descent for emergencies;
- Auto-balancing cables to prevent uneven wear;
Variable-Speed Control: 4-6 m/min adjustable speed for workflow synchronization.

Advantages

Food Safety Certified: Meets global hygiene standards, cutting cleaning time by 50%;
Space-Saving: 30% lower installation cost with pit-free design;
100% Safety Uptime: Zero critical incidents in 12-month operation;
Heavy-Duty Performance: 200+ daily cycles at 3-ton capacity, 10+ year lifespan;
Aesthetic Flexibility: Gray/blue coating blends with factory environments.
