Selection
① Checking the transported items and working environment
The conditions for conveyed materials are even more restrictive than those for Roller Conveyor, so please pay close attention and confirm them carefully. Otherwise, the selection process is generally the same as for Roller Conveyor.
① Conditions of transported goods
- External dimensions (length, width, height) and flow direction.
- Mass per unit (maximum and minimum if multiple types are used).
- The shape and material of the transported items, such as cardboard cases, plastic cases, wooden boxes, etc.
- Condition of the bottom surface (pay attention to unevenness and protrusions)
② Conveyance amount conditions
- Are the items packed tightly together on the conveyor, or are they spaced apart at an appropriate distance?
③ Working conditions
- Either room temperature, high temperature, or low temperature.
- How much water and humidity is there?
④ Loading conditions
- How to load items onto the conveyor?

② Width selection
Select the width of the abacus conveyor and the row spacing of the roller carriers according to the external dimensions of the transported items.
① Abacus conveyor
- The width should be at least 50mm larger than the width of the bottom of the item being transported.
② Colocon carrier
- The row spacing should be 0.6 to 0.7 times the width of the bottom of the transported items.
- The row spacing can only be adjusted for straight rows, not curved rows.
- The approximate width of the transported items that can be transported within the row spacing adjustment range is 160 to 750 mm.

③ Wheel type selection
Select the wheel model that best suits your operating conditions, taking into account the wheel's characteristics. (When using Corocon wheels on a frame other than the standard frame, also consider the wheel's strength.)
④ Wheel pitch selection
Always make sure that each row of transported goods is supported by at least four wheels. Also, make sure that the load on each wheel is below the allowable load.

⑤ Selecting the leg mounting pitch
As a guideline, one leg should be installed every 1,800 mm on straight sections. Intermediate legs are always required on curved sections. For details, refer to the "Strength table for two frames." Convert the mass of the transported item into mass per m and select a leg installation pitch that is equal to or less than the allowable load.
Strength table for two frames

⑥ Guide to selecting the self-propelled gradient (incline angle)
The self-propelled gradient will vary depending on the condition of the bottom surface of the transported object, the material, and the weight, but please refer to the table below as a rough guide.

*If the bottom surface is made of a soft material such as cardboard, a large amount of material will get stuck in the rollers, causing increased resistance.

Part names
Soroban conveyor

FW = Frame internal width, Machine width = (Steel frame: FW+60, Aluminum frame: FW+50), L = Machine length, H = Machine height, P = Wheel pitch, θ = Curve angle, Leg mounting holes (Steel frame: φ9, Aluminum frame: φ8.5)
Corocon Carrier

W1 = row spacing L = aircraft length H = aircraft height P = wheel pitch θ = curve angle Center R = central curve radius W1 = 115 (110), 230 (220), 340 (330), 450 (440), ( ) is OKR38BS
*The basic unit for the Corocon carrier is one row, but it is generally used in two rows. The two-row and three-row types have end bases built in, and the 2,400mm long model also has a center base built in.
