Gravity conveyor components

Gravity conveyor frames, rollers and supports

A gravity conveyor is ideally suited for handling operations which cannot justify the expense of powered equipment.

They provide an efficient and economical way to move manufactured goods from one process to the next, increasing your productivity and reducing labour costs.

Gravity conveyors are also very easy to set up, dismantle or relocate. They work on one of the following principles:

• One stand is lower than the other, and gravity moves the load.

• The frame is level, and the load is pushed along.

Gravity conveyor frames, rollers and supports are available in a variety of standard sizes and configurations.

Frames

Australian manufactured conveyor frames

Frames are all laser cut (matched) C-channels with fully-welded cross braces. Butting plates on ends are integral and folded as part of the laser process.

Three standard frame widths:

• 305, 460 and 610 mm (measurement is over the frame).

Two standard frame lengths:

• 1500 and 3000 mm.

Medium heavy duty frames can only be supplied with MHDGAL or POLY rollers with 3/8" round shafts. Heavy duty frames can only be supplied with HD rollers with 12 mm round shafts

Features

• Frames have fully welded cross braces (frames are not bolted together).

• Frames have laser cut holes at 79 mm and 115 mm pitch as standard, with laser cut holes in the bottom of the channels to allow supports to be mounted in three positions (each end and at mid-span on the 3 m frames) and two positions (each end on a 1.5 m frame).

• Each end of the folded butting plates are pre-drilled to allow splicing together.

• The tops of the frames have holes pre-drilled to allow for the mounting of guide rails if required.

• Painted Hammertone Regal Blue painted finish.

Supports

RHS supports are bolted to the frame through a crescent plate which allows for angular alignment. They have a strong, rigid construction, making them suitable for more permanent conveyors.

Straight frames require only one support per join (ie, three supports for two frames). However, if the frames are to be moved, it is usually more convenient to have a support at each end (ie, four supports for two frames).

Features

• RHS construction.

• Height is adjustable from 600 to 900 mm (1000 mm to top of roller when fully extended).

• Hammertone Regal Blue painted finish.

• Supports can be bolted to the floor and to the conveyor system for added stability.

• Supports can be ordered with capped ends and a single hole to allow castors to be fitted.
