C-Type vs. Z-Type: Why the Layout Changes the Machine

The main difference between a C-Type and a Z-Type continuous vertical conveyor is the position of the infeed and discharge.

A C-Type has the infeed and discharge on the same side of the machine. A Z-Type has them on opposite sides.

Configuration	Infeed	Discharge	Typical layout
C-Type	Same side	Same side	Both transfer points face the same direction
Z-Type	One side	Opposite side	Product enters and exits in opposite directions

The difference looks simple on a layout drawing, but it changes the carrier circulation inside the machine.

In a Z-Type arrangement, the carrier follows a relatively direct path between the lower and upper transfer points. With a C-Type arrangement, the carrier needs to return to the same side after completing the transfer cycle. This requires an additional return section and generally more chain, carrier and structural material for a comparable machine.

The C-Type configuration can also affect the achievable operating speed. However, it would be inaccurate to say that every C-Type conveyor is slower than every Z-Type conveyor. The actual speed depends on the product dimensions, load, carrier pitch, lifting height, drive system and required throughput.

For this reason, the C-Type or Z-Type configuration should be selected according to the production-line layout first, and the conveyor speed should then be determined from the complete material flow.

Coordinating the Infeed and Discharge

A continuous vertical conveyor is designed around continuously circulating carriers. The main vertical conveyor can keep running during normal operation, while the horizontal conveyors control when products are transferred.

At the infeed side of this project, the horizontal conveyor starts and stops according to the loading sequence. When a suitable carrier reaches the loading position, the infeed conveyor transfers the product onto the carrier. After the transfer is completed, the infeed conveyor stops and waits for the next carrier.

This keeps the product flow synchronized with the carrier movement rather than allowing the infeed conveyor to continuously push products toward the lifting mechanism.

The discharge side has an additional protection function.

A sensor is installed at the discharge area to detect whether products can leave the machine normally. If the downstream conveyor becomes blocked and the product cannot transfer out, the sensor sends a signal to the control system and the vertical conveyor stops.

This prevents the machine from continuing to send products into an occupied discharge area and reduces the risk of product collision or mechanical interference.

The control sequence is therefore part of the conveyor design. The vertical conveyor, infeed conveyor and discharge conveyor need to exchange the necessary signals so that the complete material flow can operate correctly.

Why We Integrated the Electrical Cabinet Into the Conveyor Frame

The electrical control cabinet on this machine is built into the conveyor frame instead of being mounted outside the machine.

This keeps the cabinet within the overall equipment footprint and avoids the extra space required by a control box projecting from the side of the conveyor.

This can be useful when the vertical conveyor is installed close to a wall, another conveyor, a safety fence or other production equipment. There is no separate cabinet taking up additional space beside the machine.

It also gives the machine a cleaner overall appearance. An external control box normally projects from the main frame, while the integrated design keeps the electrical system within the structure of the conveyor.

The cabinet layout was also designed with installation and maintenance in mind. The internal wiring is arranged in an orderly manner, with numbered wire markers corresponding to the electrical drawings.

Numbered Wiring for Easier Site Connection

The external wiring of a customized machine needs to be easy to identify, especially when the equipment is installed at the customer's factory.

For this project, the wires are marked with numbered sleeves. The numbers correspond to the terminals and signals shown on the electrical drawings.

During installation, the electrician can check the required connection on the drawing, find the same number on the wire marker and make the external connection accordingly.

There is no need to trace an unidentified cable through the entire control cabinet.

The same method can be used for connections to the infeed conveyor, discharge conveyor, sensors and other external control signals. A qualified electrician can complete the field wiring using the electrical drawings and the numbered wire markers.

This also makes future maintenance easier. If a signal needs to be checked, the technician can locate the corresponding terminal from the drawing and find the wire directly.

It is a simple detail, but it makes the equipment easier to install and service after delivery.

Safety Guard Options for Different Installations

The standard safety enclosure for the conveyor uses mesh panels to separate the moving carriers and chain system from the operating area.

Mesh is suitable for many indoor installations because it provides physical separation while keeping the machine visible during operation.

The enclosure can also be changed according to the installation environment and customer requirements.

Guard option	Typical application
Mesh panel	Standard indoor installation
Polycarbonate panel	Enclosed installation with good visibility
Acrylic panel	Transparent enclosure
Steel panel	Solid enclosure
Sealed panel structure	Outdoor installation

For outdoor installations, the guard can be changed to a closed panel structure with appropriate sealing at the joints to provide better protection against wind and rain.

Polycarbonate or acrylic panels can be used when the customer wants a more enclosed machine while maintaining visibility of the carriers and products. Steel panels are suitable when a solid enclosure is preferred.

The guard type is best confirmed during the design stage because it can affect the frame, access doors, maintenance openings and overall machine dimensions.

What We Need to Design a C-Type Continuous Vertical Conveyor

For a C-Type project, lifting height, product weight and speed are only the starting points.

The machine needs to be designed around the complete material flow. The key information normally includes:

Parameter	Required information
Product size	Length × width × height
Product weight	Maximum product weight
Throughput	Cartons / boxes per hour
Lifting height	Lower to upper transfer height
Infeed height	Conveyor elevation
Discharge height	Conveyor elevation
Layout	Same-side infeed and discharge
Installation	Indoor or outdoor
Guard	Mesh / PC / Acrylic / Steel
Power supply	Voltage / frequency
Control interface	I/O / Modbus / other

Product dimensions and weight determine the carrier and transfer design. Required throughput determines how frequently products need to be loaded and discharged. The position of the infeed and discharge conveyors determines whether a C-Type or Z-Type configuration is suitable.

Once these conditions are confirmed, the carrier arrangement, machine dimensions and control sequence can be designed around the actual production line.

Designed Around the Actual Material Flow

A C-Type continuous vertical conveyor is used when the infeed and discharge need to remain on the same side of the machine. That layout requirement affects the carrier return path and therefore the mechanical structure.

The project shown here also includes several details intended to make the machine easier to integrate and maintain: the infeed conveyor is coordinated with the continuously circulating carriers, a discharge sensor stops the machine if the downstream area is blocked, and the electrical cabinet is integrated into the conveyor frame.

The numbered wiring provides a direct reference between the machine wiring and the electrical drawings, while the safety enclosure can be adapted for different installation environments.

These details are part of the engineering of the conveyor itself. The machine is designed around the customer's material flow, available space and connection requirements rather than treated as an independent lifting unit.
