CVL-300 Continuous Vertical Lift Conveyor
The CVL-300 Continuous Vertical Lift Conveyor offers a quick vertical transport solution ideal for continuously high-volume material handling facilities. Compared with reciprocating lifts that shift one carriage back and forth, the CVL-300 employs a circulating platform concept which makes it possible to transport several items simultaneously. This "endless loop" system ensures a non-stop delivery of goods and therefore is a perfect option for the most demanding sorting centers and production lines where every second of throughput is vital.
Without the downtime of return cycles, the system effectively facilitates transfer between various floors while at the same time maximizes operational uptime and completely removes bottlenecks at floor-to-floor junctions. Besides its small vertical footprint and smooth, synchronized movement, it guarantees that parcels, totes, and cartons are handled both rapidly and safely thus enabling logistics managers to reach higher processing rates within a limited space.
Key Features & Advantages
Continuous and uninterrupted operation
The CVL-300 has been engineered so that the lift’s “waiting time” usually present with standard reciprocating lifts gets completely eliminated. Through the operation of a continuous loop comprising several carrying platforms, it is possible to ensure vertical transport at all times without interruption. With this architecture based on flow-through, there will be no need for your horizontal conveyor lines to halt because they are awaiting the carriage’s return, thereby preserving a steady rhythm without any interruptions which is vital for fast sorting and distribution centers.
Optimal use of vertical space
The CVL-300 is specifically designed to work efficiently in tight and cluttered industrial environments by carrying out the vertical movement of goods within a very small footprint of structural mast. Thus, the set-up does away with inclined belts that are lengthy and require a lot of space or with large spiral chutes. By keeping the ground-level just a small area, the valuable floor space can be utilized for other production machines, designated pathways for forklifts, or storage racks resulting in the maximization of the cubic usefulness of your facility.

Customer concerns (FAQ)
Q1: What is the major operational difference between a Continuous Vertical Lifter (CVL) and a Reciprocating Vertical Conveyor?
A: To understand the difference, picture a VRC as an elevator that can only carry one load at a time and has to make a return trip. On the other hand, a CVL is like a vertical production line. It works with
a continuous loop of several load carrying platforms and goods are moved nonstop. For a high task frequency with, for example, parcels or totes, a CVL generally gives 3 to 5 times as much output as a VRC.
Q2: What handling throughput capacity can be reached by the CVL-300 system?
A: The CVL-300 is a very powerful machine which is designed for high throughput cases. Based on your particular item size and platform spacing arrangement, it can produce in the range
of 2,000 - 3,000 pieces per hour. The continuous production flow vertically frees you from bottlenecks in multi-level warehouses so that your floor-based sorting lines are always operating at their highest level.
Q3: How much floor space will I need for this?
A: Not much. The CVL's best feature is its very small footprint. If you compare spiral chutes or inclined transport belts, which take up large amounts of horizontal space,
a CVL requires only a few square meters. So it can perfectly serve you as a solution for a facility retrofitting, or those city distribution centers with very limited space.
Q4: Will the system be able to transport different package sizes together without manual changing?
A: Indeed. Provided the different items do not exceed the maximum platform size, the system will perform
Mixed Flow Transport. Smart sensors continuously watch to see the spacing of the incoming items and automatically adjust the lift speed accordingly. This ensures that various box sizes or totes enter the platforms smoothly and safely without human operation.
Q5: What kind of maintenance should I expect in the long term for a system operating around the clock?
A: Duffy Machinery has made chains of very high material strength as well as guides of self-lubricating types that help to reduce both friction and wear. Our knowledge gained from producing
800,000 rollers annually leads to drive components which comply with the highest precision requirements. System’s service life can easily surpass 10 years under
heavy-duty conditions if it only undergoes basic routine inspections and lubrications.
Q6: How is the system able to keep cargo secured while traveling at high speeds vertically?
A: The system incorporates different layers of safety. There are crush prevention sensors for the
entry area, platform alignment is monitored continuously during the whole lift, and the outlet location where the stuff is gathered basically has a detection mechanism for accumulation of the material which is to be released.
A system whose PLC is capable of triggering a very short emergency stop if a misalignment or downstream jam should be detected can prevent product damage or mechanical failure.
Q7: Is it possible that a single CVL unit provides vertical transportation to several floor levels?
A: Not only possible but very easy. First, we do supply intake and discharge at multiple levels that are cus-tomized to your needs. Then, through use of pneumatic diverters or sliding gates, a
goods sorting and routing system can be installed to allow same or different goods to be taken up to or brought down from different floors as per the requirements of the facility layout.
