Hydraulic floor jack body material
Hydraulic floor jacks are made out of steel or aluminum. The material does not significantly impact the lifting capacity of the hydraulic jack.
- Steel hydraulic floor jacks weigh approximately 45 kg (100 lbs). They are heavier than aluminum, but the body can resist damage much better. Steel hydraulic floor jacks are ideal for staying in a garage.
- Aluminum floor jacks weigh approximately 27 kg (60 lbs). These jacks are more suitable than steel jacks for portability to different worksites. Aluminum floor jacks can handle most garage lifting tasks.
