The difference between an 8 m, 10 m and 12 m scissor lift sounds simple until the buyer compares the working envelope. A taller model can reach higher, but it may carry less, weigh more and take longer to raise. The right choice depends on the height the team must reach, the tools going up with them and the route the machine has to follow indoors.
What do 8 m, 10 m and 12 m mean on a scissor lift?
Those figures normally describe platform height, not the height a person can reach. The GTJZ08 has an 8 m platform height and a 10 m working height. The GTJZ10 raises the platform to 10 m and reaches a 12 m working height. The GTJZ12 has a 12 m platform height and a 13.8 m working height. Each working height is the manufacturer’s figure for that model, so compare the stated numbers rather than adding a blanket allowance to every machine.
Start with the highest point the job requires, but include the work itself. Someone servicing a ceiling fixing needs the platform at a useful position below it, with tools and materials on the deck. A task at exactly 10 m may point to the GTJZ08 because its working height is 10 m, or it may require the extra reach of the GTJZ10 depending on the operation and access position. Confirm that on the site rather than choosing by the model name alone.
How do the 8 m, 10 m and 12 m models compare?
The three machines share a similar platform length, but capacity, weight and drive details change as height increases.
| Specification | GTJZ08 | GTJZ10 | GTJZ12 |
|---|---|---|---|
| Platform height | 8 m | 10 m | 12 m |
| Working height | 10 m | 12 m | 13.8 m |
| Rated load | 450 kg | 320 kg | 320 kg |
| Platform size | 2270 x 1120 mm | 2270 x 1120 mm | 2270 x 1140 mm |
| Machine weight | 2,208 kg | 2,450 kg | 3,000 kg |
| Lifting and drive motor | 24 V / 3.3 kW | 24 V / 3.3 kW | 24 V / 4.5 kW |
| Lifting speed | 6 – 9 m/min | 6 – 9 m/min | 3 – 5 m/min |
| Turning radius, inner / outer | 0.15 m / 2.3 m | 0.15 m / 2.3 m | 0 m / 2.5 m |
When is the 8 m model the practical choice?
The GTJZ08 combines an 8 m platform height with a 450 kg rated load on a 2270 x 1120 mm platform. It weighs 2,208 kg, uses a 24 V / 3.3 kW lifting and drive motor, and raises at 6 to 9 m per minute. Those figures make it the stronger choice when the work fits within its 10 m working height and the team needs to carry more tools or material.
The smaller model also has the same 0.9 m extension deck as the 10 m unit and an extension-deck capacity of 113 kg. Compare 450 kg against 320 kg on the two taller machines when the payload is not just one person. Leaving capacity for tools, fixtures and material is part of selecting a safe working configuration; the rated load is a limit, not a target to fill.
When does the 10 m model make sense?
The GTJZ10 provides a 10 m platform height and 12 m working height with a 2270 x 1120 mm platform. Its rated load is 320 kg, machine weight is 2,450 kg, and the 24 V / 3.3 kW motor gives a lift speed of 6 to 9 m per minute. It sits between the higher-capacity 8 m machine and the heavier 12 m model.
A real project in Kenya selected the GTJZ10 for a 10 m platform height and 12 m working height. The recorded configuration includes a 2270 x 1120 mm deck, 320 kg capacity, 2,450 kg machine weight, 24 V / 3.3 kW power, 6 to 9 m/min lift speed and 25% gradeability. That case is useful because it shows a buyer matching the model to a known platform height rather than choosing the largest unit on the list.
When is the 12 m model necessary?
The GTJZ12 reaches a 12 m platform height and 13.8 m working height. It carries 320 kg on a slightly different 2270 x 1140 mm platform and weighs 3,000 kg. Its lifting and drive motor is 24 V / 4.5 kW, while the lifting speed is 3 to 5 m per minute, lower than the 6 to 9 m per minute of the 8 m and 10 m models.
The 12 m unit is the logical candidate when the work needs the extra platform height and the site can handle its weight and movement. Its inner and outer turning radii are listed as 0 m and 2.5 m, compared with 0.15 m and 2.3 m on the 8 m and 10 m models. Check the route, doorway dimensions and floor loading before treating the three machines as interchangeable on site.
Why did one buyer compare all three heights?
A project in Slovakia requested quotations for the GTJZ8, GTJZ10 and GTJZ12 as a three-height comparison. The quotation can show what each added metre of reach changes in capacity, weight and speed. The figures should then be checked against the highest task, the tools and the route.
The range data makes the trade-off visible. Moving from the 8 m to the 10 m model raises the platform and working height by 2 m, reduces the rated load from 450 kg to 320 kg and increases machine weight from 2,208 kg to 2,450 kg. Moving to the 12 m model gains another 2 m of platform height, leaves the load at 320 kg, raises weight to 3,000 kg and lowers the lifting speed. There is no single best model without a specific job behind the comparison.
What site checks decide between them?
Measure the narrowest doorway, the available aisle width and the turning area at each work position. The self-propelled design allows the operator to drive, steer and lift from the platform controls, so the route matters as much as the work height. Check the fully stowed length and width, the floor condition and the ramp or lift used to move the machine into the building.
Also confirm the floor can carry the selected model. The difference between 2,208 kg, 2,450 kg and 3,000 kg is significant before the operator and tools are added. The machines use non-marking solid tyres and have a listed gradeability of 25%, but those figures do not replace a check of the actual surface and access route.
Frequently asked questions
Is the working height the same as the platform height?
No. For the three models in this comparison, the GTJZ08 has an 8 m platform height and 10 m working height, the GTJZ10 has 10 m and 12 m, and the GTJZ12 has 12 m and 13.8 m. Use the stated value that matches the task instead of treating the model number as both measurements.
Which model carries the most?
On the listed specifications, the GTJZ08 carries 450 kg, while the GTJZ10 and GTJZ12 each carry 320 kg. If the platform load is the deciding factor, confirm the weight of people, tools and materials after deciding how much height is genuinely needed.
Does the 12 m model fit the same aisles as the 10 m model?
Do not assume it does. The 12 m model weighs 3,000 kg, has a 2270 x 1140 mm platform and lists turning radii of 0 m inside and 2.5 m outside. Measure the route and compare the full model drawing with the site; a small height increase can change the practical transport and floor requirements.
