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
Does not protrude over floor 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 pivots up the two edge gates to the vertical position either side of the opening. See video on this page.
When used with standard pallets the side frames can be reduced for space saving and allows good access to a pallet on three sides. This model can also be used with a vacuum handling crane for unloading bags or sacks etc. Read more about special applications below. With 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 it allows the inner gate to fold up, under the runway, behind the load when landed.
The construction is a combination of our tried and tested standard tube and component construction merged with specially designed pivot joints and tube rotators.
This design allows us to produce a bespoke low-cost gate which can be easily adapted (See below) not only in height, width and depth but will also be easy to assemble and adjust on site to ensure optimum operation
- All galvanised
- Safety yellow thermoplastic (Warm to touch) coated tube and galvansed components
- Special RAL colour powder coated tube
In addition to normal forklift loading, this model can be used with hoists, in doorways, and with vacuum handling cranes - See notes below

*Dimensions are approximate only. Due to differences in the tube clamps and the assembly process, the actual
dimensions may vary. Any critical dimensions such as hole fixing centres should be determined when the product
is actually on your site. We reserve the right to change the design without notice
❶ Bespoke inside width - We recommend that you allow at least 200 mm load clearance for the inside gate
❷ Overall width including side frames. e.g. 2000 mm gate inside width = 2800 mm gap required (Overall width)
Standard Installation requires 8 x M12 Bolts/Anchors (Not provided)
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 height and depth of the load to be cleared by the fold down inner gate and the length of 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 fold-down gate behind load depth, we recommend that you allow at least 150mm load clearance on inside height to use pallet truck to remove 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 needs to be closed to access the load. The load has to be landed to disconnect from the hoist within the safety area. By landing onto a suitable trolley or pallet truck.it 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.
Unloading pallet contents 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 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.
This model can also be used with inward opening doors (See case study or 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 foulded 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 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 which will need to land on a ledge. If no ledge exists, you will have to bolt a door width bracket to the wall under the outer face door sill. This is a ISO standard requirement to prevent items falling through the gap between the door cill and the kick plate.
