Sigma Bespoke Multi-Purpose Safety Pallet Gate

This new concept pallet gate has features designed to solve specific problems not addressed by other models.

What’s so special?

Conforms to BS EN ISO 14122-3:2016 Mezzanine Gates

It does not protrude over the floor's edge. No overhead bars when loading. Less risk of damage during the loading operation.

Fitted with 100 mm high Aluminium kick plate

When the operator pulls down the inner gate, the mechanisms incorporated in the side frames automatically pivot up the two edge gates to the vertical position on either side of the opening. See the video on this page.

When used with standard pallets, the side frames can be reduced for space-saving, allowing good access to a pallet on three sides. This model can also be used with a vacuum-handling crane for unloading bags, sacks, etc. Read more about special applications below. With the inner gate raised this model offers more usable floor space for confined areas.

The design can be adapted for use with inward-opening doors or roller shutters and is especially useful for use with hoists on low runway beams. When the gates are fitted to deeper side frames, the inner gate folds up, under the runway, behind the load when landed. 

Special notes:  (You can tell us about any special features or extras you require in the additional information box.

The depth of the gate will vary according to the height and depth of the load to be cleared by the fold down the inner gate and the length of the side frames. Overall height varies according to the length of side frames.

Usually, there is a trade-off between space-saving and load clearance requirements. The longer we can make the side frames the lower the fold-down inner gate can be to clear the load. 

For minimum height with a fold-down gate behind load depth, we recommend that you allow at least 100mm load clearance on inside height to use a pallet truck to remove the load..

Information we need:

The maximum size pallet(s) or load W x D X H. We will need to know the unrestricted headroom above the gate location.  The available gap for the gate to operate within. The available operating depth and how the gate will be loaded e.g. forklift or overhead hoist. 

.Loading by hoist

If you intend to use the gate for loading with a hoist with or without doors, the side frame will need to be of sufficient length for the inner gate to fold back up behind the load. The inner gate must be closed (Vertical) to access the load. The load has to be landed to disconnect from the hoist within the landing safety area. Landing onto a suitable trolley or pallet truck allows a non-wheeled load to be moved further in. We will need the height to the underside of the runway beam.   Special note: If headroom is very tight, you may need to alter the hoist feed system as the gates could foul the hanging festoon cables or change feed to a conductor bar system.

Unloading load/pallet with a hoist

For applications where the palletized load is to be unloaded e.g. vacuum hoist for sacks. The side frames can be made with minimum depth, and the inner gate can be raked forward in the folded position when shut. This allows the hoist to swing over the entire pallet. If you can give us the precise dimensions, we can calculate the optimum dimensions required to clear the load. Note: We also supply the Vaculex sack lifter shown in the photo.

Doorway applications

This model can also be used with inward opening doors or roller shutter doors (See case study for roller shutter opening. If the door has a deep ledge or external dock, it may be possible to install the gate totally outboard of the door. The inner gate can be folded down when the door is opened. Alternatively, to instal the gate as shown left, you will need to drill 6 x 50 mm diameter holes in the wall, three on each side of the door frame for the active mechanism tubes which hold the outer gates. The wall can be grouted flush around the holes after installation.  We will require the proposed hole cross centres and the thickness of the wall to finalise the arrangement. The outer or edge gates have a kick plate that must land on a ledge. If no ledge exists, you must bolt a door-width bracket to the wall under the outer face door sill. This ISO standard is required to prevent items from falling through the gap between the door sill and the kick plate. Sigma Doorway Gate Questionnaire E-form PDF
