TrestleJacks for Workshops

The new time and money saver

The tried and tested TrestleJack is a 2-in-1 device specifically designed to lift and support the axles of heavy commercial trailers in complete safety. TrestleJacks use the driving motion of the tractor to lift and lower trailer axles while the driver stays safe in the tractor cab.

Hydraulic jacks and similar lifting equipment require someone to work underneath the trailer at considerable personal risk. Each TrestleJack comes with a load certificate valid for 1 year, a standard operating procedure and risk assessment document to help operators familiarise themselves with all safety aspects.


Using TrestleJacks in a workshop tyre yard, or bearing or brake lining workshop, should result in higher profits as more vehicles can be serviced in less time. Service providers in the commercial trucking industry all share tasks in common - and lifting axles safely and efficiently is one of them. Once operations are integrated and streamlined, significant time savings can be achieved. Practically speaking, why would anyone need a jack to lift an axle onto a trestle if a TrestleJack - which is essentially a safe axle stand – can do the lifting much more effectively on its own? In the upright position, TrestleJacks can be locked in place by using the belt to strap the two front jacks to the jack stand of the trailer.

When combining a capable tool with well-planned operations, more vehicles can be put back on the road faster. Using a motion-driven lifting device makes more sense than relying on the speed of a single person operating manual equipment, or using air powered tools and still requiring additional safety equipment.


Health and Safety

Current lifting equipment (CLE) used as standard on all HCVs is designed to cover a wide range of applications. On the trailer axle, CLE can be used for one purpose only, that of lifting an axle. By design it is not a complete solution and requires additional equipment to support the axle.

According to the CLE operating manual, a blocking device is required to support the weight of the axle. Most trucks on South Africa’s roads do not carry a blocking device such as a trestle or axle stand.

Occupational Health and Safety standards require employees to be kept safe. Supplying the right tools for the job helps to minimise safety risks. However the implementation of safety guidelines is hampered by CLE that requires additional equipment and human effort.

Using the right tools for the job helps to minimise safety risks. However CLE places the burden on the equipment operator to perform the required steps. Therefore the implementation of safety guidelines is hampered by the fact that CLE requires additional equipment and more effort. Are you 100% confident that your employees are kept safe when you are not watching?

Using a TrestleJack - which is both a jack and a trestle - to safely lift troubled axles whilst the driver is kept secure in the cab, makes this the safest lifting method currently known. All other similar equipment requires a person to be underneath the trailer during the operation of lifting and lowering axles.

Fastest axle lifting

Whether you are repairing tyre damage next to the road or in a workshop, TrestleJacks can get your customer’s vehicle back on the road in less time. A single side can be lifted in less than a minute and an entire empty trailer in less than seven! In the commercial trucking industry, time literally means money. Tyre service providers using TrestleJacks next to the road can save 25 minutes in lifting and lowering an axle. The Health & Safety personnel of service providers are now guaranteed that the safest tools and methods are used as part of their tyre maintenance programme. Service providers replacing a set of tyres on a trailer can now save their customers 86% and more of lifting and lowering time - by using TrestleJacks to lift an entire trailer in one go. This means that you can serve more customers on the roadside and in your workshop.

TrestleJacks vs. Conventional Systems

In a workshop environment where a heavy load 4 axle trailer requires repairs (eg changing brake linings or bearings), using conventional lifting systems requires more effort than using TrestleJacks.

As an example, say we need to lift 1 trailer a day and 4 lifts a week over a period of 50 work-weeks and we use 2 labourers to do the lifting work. In one scenario we use TrestleJacks and in the other we use conventional methods (Bottle/Trolley Jack & Trestle Stands). Below you will see the results of comparative calculations based on these assumptions:

TrestleJacks use case


  1. 1 x 3 axle trailer running on 12 x R22.5 tyres or 6 x R22.5 super singles.
  2. 6 x TrestleJacks 30 Ton R22.5 Workshop units (2 per axle)
  3. 1 x Labourer.

Conventional use case


  1. 1 x 3 axle trailer running on 12 x R22.5 or R22.5 super singles.
  2. 6 x Trestle Stands
  3. 1 x Trolley Jack 30-Ton or 1 Bottle Jack 30-Ton
  4. 2 x Labourers.
