Gravity Conveyors - Graded Materials, Compact Design, Corrosion Resistant | Flawless Functioning, Speedy Operations, Customizable Versions

1. General Description

The gravity conveyor system shall be modular, heavy-duty, low-maintenance, and designed for smooth movement of unit loads without powered drive.

2. Conveyor Type
TypeApplication
Roller ConveyorCartons, pallets, boxes
Skate Wheel ConveyorLightweight packages
Ball Transfer TableMulti-directional movement
Pallet Gravity ConveyorHeavy pallet handling
3. Design Specifications
ParameterTypical Specification
Conveyor Length130 m
Conveyor Width3001500 mm
Roller Pitch75150 mm
Load Capacity202000 kg/m
Conveyor Height4501200 mm
Conveyor Slope25% typical
Operating Temperature-20C to +60C
4. Conveyor Speed Principle

Gravity conveyor flow depends on slope and friction.

Basic force relation:

F=mgsin

Where:

F = gravitational force component
m = load mass
g = acceleration due to gravity
= conveyor inclination angle
