Gravity Conveyors
The Lemcol range of gravity conveyor will enable goods of various shapes, sizes and weights to be moved quickly, efficiently and safely from one operational stage to the next.
Your choice of roller or wheel conveyor will depend on the nature of the articles to be moved. Generally, goods that are heavy or less uniform in shape, or both, will require roller conveyors. Lighter and more uniform articles may well suit the use of wheel conveyor, which have the capacity to move goods quicker.
12 Month Warranty
All products in this range carry our standard 12 month warranty against faulty workmanship and materials, and is backed by a service and parts network Australia wide.Roller Conveyor Frame (90x28x2.5 channel)
Available in both straight and curved sections, the side channel is made from 2.5mm thick material, folded into a 'C' section for strength.
The cross members are made of inverted 40x40x3mm angle iron, strategically welded into position to reinforce the section and provide a bed for the rigid support.
There are standard lengths for straight sections (1500mm and 3000mm) and curves (45 degree and 90 degree).
'Oval' axle holes to suit our standard Lemcol gravity rollers are punched at 37.5mm centres for flexibility of roller pitch.
Sections interlock to form a positive and secure join between frames, allowing the flexibility to add or reduce sections as required. Straight sections incorporate a bar coupler at one end and a hook coupler at the other. Curved sections have universal couplers at both ends.
In-house manufacture allows the flexibility to provide non-standard lengths or widths upon request.
Rigid Supports
Lemcol rigid supports provide a firm foundation for all the roller and wheel conveyor sections in the range.
Made from tubular construction and fully welded for strength and reliability, each stand can be individually adjusted to the height required. A range of models is available to suit various frame widths, providing the choice of operating heights from 305mm to 1320mm.
While supports have the flexibility to be used as freestanding units, it is recommended that they are bolted into position to ensure operator safety.
Gravity Rollers - Oval Axle
The standard range of Lemcol rollers are manufactured with an 'oval' shaped formed axle. This effectively locks the axle in the frame and holds the inner bearing firmly thus ensuring maximum efficiency from the ball race. An internal spring at one and enables the axle to be laterally moved for ease of assembly, alterations to roller pitch or removal for maintenance.
Three ranges are offered to suit standard applications and operating conditions. The rollers in curved sections are of the double differential type, enabling cartons etc. to maintain a controlled course and not wander to the outside of the curve.
Although manufactured to suit the Lemcol gravity conveyor frame, non-standard lengths and axle types are available on application.
If adverse operating conditions are encountered, it is important that you refer to your nearest Lemcol representative to ensure the best selection possible. For instance, galvabond rollers and polypropylene rollers with sealed stainless steel bearings and axles are available to suit moderate to heavy corrosive conditions.
As roller capacities quoted are for moving flat objects, selection should also take into account possible impact, where a heavier roller is more suitable.
For ease of movement and reduction in damage, there should always be a minimum of three rollers under the commodity at all times. Where there are multiple sizes of products involved, roller pitch is determined by the smallest commodity to be moved.
Bearing inner and outer is manufactured from acetal with a single row of carbon steel balls.
Bearing is all steel construction, incorporating a hardened steel, caged ball bearing, shielded and greased.
Bearing inner and outer manufactured from acetal with a single row of carbon steel balls.
UV stabilised but suitable for indoor use only.
Lightweight, quiet running rollers used to reduce possible damage.
Suitable where corrosive elements may affect efficiency or hygiene standards however they are not suitable for extreme corrosive conditions, where non-standard bearings and shaft material would be required.
Wheel Conveyors
These very free rolling conveyors are ideal for moving all types of light packages with flat or semi-flat surfaces (cases, packages, crates etc.). Their free rolling ability is particularly useful where long distances of travel are necessary with a minimum gravity decline.
Lemcol wheel conveyors are available in two types, steel wheels for medium-weight handling and nylon wheels for lightweight use. Both systems are interchangeable and offer a choice of widths and lengths.
Wheel conveyors work efficiently with a pitch (or axle spacing) of 75mm or 150mm, depending upon the type of goods to be handled. Wheel positions can be varied to suit individual requirements by adjusting the wheel spacers and by adding or removing wheels as required.
Wheel Conveyor Frame (65x25x2.5 channel)
Available in both straight and curved sections, the side channel is made from 2.5mm thick material, folded into a 'C' section for strength.
The cross members are made from 2.5mm steel, formed and strategically welded into position to reinforce the section and provide a bed for the rigid support.
There are standard lengths for straight sections (1500mm and 3000mm) and curves (45 degree and 90 degree). Both are available in standard overall widths of 300mm and 450mm.
Sections interlock to form a positive and secure join between frames, allowing the flexibility to add or reduce sections as required. Straight sections incoroporate a bar coupler at one end and a hook coupler at the other. Curved sections have universal couplers at both ends.
In-house manufacture allows the opportunity to provide non-standard lengths or widths upon request.
Wheel Tracks
These versatile wheel tracks can be used in a wide variety of warehousing and materials handling situations. Available in either standard 75mm or 150mm pitch, they are ideal for use in warehousing shelving for the deep storage of parcels. As the front parcel is removed, the whole line moves up to take its place.
The simple design has a line of conveyor wheels mounted in a 2mm thick pressed steel frame with provision for mounting to any flat surface. The axles are 1/4 BSW x 1 1/2" ZP hex set screw with nyloc nut.
The wheel track utilises the same steel and nylon wheels used in the wheel conveyor, allowing choice depending upon load capacity and operational use.
The standard 3000mm long stracks can be cut to any length to suit specific installations. By using the tracks mounted on Lemcol rigid supports, a mini conveyor can easily be set up to suit all kinds of materials handling situations.
Mounting Options
Ball Transfer Units
These simple, but very adaptable free-rolling units enable operators to transfer most flat objects in any direction on a horizontal plane.
They are especially suited for transferring goods from one conveyor line to another, the movement of boxes of parts around machines, shifting commodities on or off scale-platforms and manipulating heavy steel plates around presses and guillotines.
They also serve as multi-directional switches and transfer stations for heavy flat objects. Where operating conditions are mildly corrosive, the standard steel balls can be replaced with stainless steel balls for greater durability.
