External Vertical Conveyor for Heavy Industry | Continuous Fork Lift

Project Overview

Analyzed through the lens of Challenge – Solution – Parameters – Workflow, the Externally-Mounted Multi-Level Fork Continuous Lifter is not merely a equipment replacement but a breakthrough systemic logistics solution.

By reconfiguring space (internal to external), re-engineering processes (dedicated logistics channel), and automating heavy-load handling, it systematically resolves the multiple contradictions of space, efficiency, safety, and continuity faced by traditional heavy industry in brownfield upgrades.

It is a strategic enabler for “zero-footprint expansion” and “non-stop production renovation.”

Basic Parameters

Way of working	One in and one out	One in, many out	More in and one out	Remark
Cargo dimensions(mm)	PL≤500	PW≤600	PH≤800	Maximum overall dimensions(If the size exceeds the size, it needs to be customized.)
Maximum weight of product shipped	≤50Kg			Heavy duty customizable
Hoist width	1590			PL＞500，Needs customization
Hoist length	AL(The length of the elevator for incoming and outgoing materials in direction A)	BL(The length of the elevator for incoming and outgoing materials in direction B)	GL(The length of the bottom of the elevator)	L(Overall length of hoist)
Hoist length	AL=1110	BL=1267	BL=985	Import and export are all in direction A=AL+200There is a B side for import and export =BL+200
Hoist height	H≥CH2+700
Stroke height	AH=CH2-CH1
Minimum distance between forks	Exit from direction A:DT=PH+PW+500		Exit from direction B:DT=PH+PL+500
Line speed	10~32			m/min
Maximum capacity	S=32000/DT*60			pieces/hour
One layer conveying height(mm)	CH1≥700	Below 700, a pit needs to be dug
Carrying capacity per square meter	1500KG	Standard machine (height 3.8 meters)	1500KG+200KG/M	Add 200KG for every 1 meter increase in height
Floor opening size(mm)	L=1250	W=1270	Normally
Air consumption	One in, one out: 0		Multiple inlets and multiple outlets: +400L/min (for each additional inlet or outlet)
Equipment material	Carbon steel paint, stainless steel

Challenge

Absolute Space Lock: Production areas and existing storage were saturated, with zero internal space available for a new vertical logistics channel.
Conflicting Process Flows: Internal transport routes for heavy materials intersected with personnel zones and precision production areas, leading to low efficiency, significant safety hazards, and cross-contamination.
Zero-Downtime Mandate: Production schedules were full, disallowing any operational shutdown for logistics renovation.
Demanding Load & Environment: Required handling of single units weighing 10-30 metric tons (e.g., metal components, large raw material modules) in an environment with dust, temperature variations, and other industrial challenges.

Workflow

Platform & Enclosure: The platform was finished with a 304-grade stainless steel, non-slip floor for easy cleaning and food safety compliance. A hygienic, powder-coated enclosure with clear viewing panels was added for safety and load verification.
Drive System & Control: The system utilizes a powerful yet smooth AC electric drive (configured for 220V), offering quiet operation essential for a hotel environment. The Programmable Logic Controller (PLC) was programmed with multiple stop points and access codes. For instance, the basement loading dock has unrestricted access, while upper-floor discharge points require key-switch activation, ensuring security and controlled access to supplies.
Safety & Reliability: It features elevator-grade guide rails for exceptionally smooth and stable travel, along with multiple safety interlocks, gate sensors, and overload protection, ensuring complete compliance with material handling safety standards.
