Key product features

Pneumatic drive system with control tiller

Pneumatic drive system with control tiller

Operators can effortlessly move pallets and IBCs around the workplace using our innovative air-driven system. A tiller handle controls the rear drive wheel offering fantastic control and manoeuvrability. Two twist throttle controls move the unit forwards and backwards and allow very fine control of the stacker, great for precision placement of loads.


The tiller is fitted with a self-righting gas ram as well as other mandatory safety features such as an emergency stop button and pedestrian warning horn.

Air-driven drive wheel

Air-driven drive wheel

We have developed a unique highly-efficient ATEX air drive system which can be fitted to a range of different STS units. A stack of mated components at the rear power the drive wheel, these components include an air motor, air brake and gearbox assembly. Each part has been carefully designed to ensure optimum drive speed and efficiency.


The drive system produces high levels of torque and a consistent smooth drive experience. The robust nature of the drive unit makes this model ideal for high-use applications where the unit will operate for years with a minimal amount of maintenance. 

ATEX weigh scale fork carriage

ATEX weigh scale fork carriage

This straddle stacker is fitted with a wireless load cell head assembly. Companies can record the weight of materials being lifted by the forks either using the handheld wireless display provided, or by linking the load cell to a base station and/or computer network.


The zoned weigh scale system utilises 2.4GHz radio waves to transmit the data. Being wireless makes this unit suitable for large scale production operations where potentially tens of units can be connected to central control locations whereby all weighing activities can be monitored and logged. The unit shown has a high accuracy of +/- 1.25kg and is able to lift weights of up to 1300kg.

Stainless steel clad forks

Straddle stacker stainless steel clad forks.

Stainless steel clad forks

Our team of fabricators clad forks in 304-grade stainless steel. This stainless steel cladding greatly reduces the risk of a thermic strike incident preventing a spark/ignition source. Our fork cladding is strong and robust and our forks can be adjusted in width to handle different loads.

Heavy duty construction

Heavy duty construction

STS units are strong, robust and hard-wearing. During the design of equipment our engineers carry out FEA stress analysis on load bearing parts to ensure adequate strength. Materials are selected to be both fit-for-purpose and long-lasting. This ATEX straddle stacker utilised hot-rolled steel profiles and premium carriage bearings to ensure loads are lifted safely. Each IBC/pallet handler is supplied with a load test certificate and EU Declaration of Conformity.

ATEX-certified for gas and dust zones 1, 2, 21 and 22

ATEX-certified for gas and dust zones 1, 2, 21 and 22

ATEX equipment is at the heart of the STS product offering. We can provide straddle stackers for hazardous zones 1, 2, 21 and 22 either manually or pneumatically powered. Each unit is manufactured to ensure electrical continuity and full compliance with the ATEX Directive. 


Each ATEX straddle stacker is shipped with an EU Declaration of Conformity which demonstrates compliance with the ATEX Directive 2014/34/EU along with relevant British Standards.

Optional features

Electric-hydraulic lift

For non-ATEX applications we adapt an STP12 (pneumatic unit) into an STE12 (electric unit). On-board batteries then power the hydraulic lift function.

Variable leg dimensions

When machinery integration is critical we will modify leg dimensions to suit your facility.

Telescopic/variable lift height

Single- and dual-mast models are available, depending on the lift height required. Single masts offer around 1450mm lift whereas telescopic masts offer 2450mm.

Sale or return

In the UK we can supply certain equipment on a sale-or-return basis, meaning you can use a unit on-site for seven days with no obligation to buy it once the trial period is up. Find out more here.
