Half-scissor hydraulic vehicle lift
Stertil-Koni says its Skylift half-scissor hydraulic vehicle lift incorporates two independent, modular lifting platforms to provide additional underchassis operator access, while its vertical lifting orientation saves working space. The independent lift units can be repositioned easily to accommodate virtually any axle width, and the Skylift’s ease of mobility makes it convenient and portable, according to the company; the lift can be installed in flush-mounted or surface-mounted configurations, enabling it to accommodate a wide variety of vehicles, axle widths and lift applications.

The Skylift is designed as a modular unit: Four legs (two under each runway) can handle a maximum length runway of up to 45 feet. The device also is built for multiple loading configurations, the company says; customers can load the lift with up to 77,000 pounds symmetrically and up to 55,000 pounds asymmetrically. The Skylift’s floor-to-ramp height is 69 inches (1.75 m), allowing for adequate headroom, and each leg is equipped with an individual measuring device to facilitate smooth, level synchronization within 5⁄8 inch. The lift also offers independent hydraulic and mechanical locking systems and has 31 mechanical locking positions. Installation is easy, according to Stertil-Koni; two technicians can install the lift in a day.

Lightweight gray iron drum
The Aftermarket Business Unit of Webb Wheel Products says its high-performing Webb Vortex brake drum, produced from standard gray iron metallurgy, is an alternative replacement drum for more expensive steel-shelled or other lightweight drums used in rear and trailer applications. The brake drum measures 16-by-7-inches and weighs 100 pounds. Webb says the Vortex design profile, with reinforcing center band and ribs, results in a conventional gray iron brake drum that weighs less, but does not compromise the structural integrity, reliability and braking capabilities expected in heavier drums. According to the company, the advanced technology contour adds 15 percent to the surface area and conducts heat away from the brake surface for added heat dissipation and lining life, resulting in a drum that runs cooler, is structurally strong and has exceptional stopping performance.

Aggressive on-/off-highway drive tire
Firestone says its FD835 on-/off-highway drive tire delivers superior traction and exceptional removal mileage in severe-service applications. The aggressive drive is suited for rugged applications in logging, construction, mining, refuse or oil field service.

The FD835, which the company describes as the first of a new generation of Firestone on-/off-highway tires, has an aggressive block tread pattern designed for superior traction both on and off the highway. Thirsty angled sipes positioned in each block are designed to cut through rain for solid wet-surface handling, while an extra-deep open shoulder design helps facilitate outstanding traction on soft surfaces, including mud and snow.

With a tread more than one full inch deep, the FD835 is designed to offer exceptional removal mileage; ultra-tough tread compounds help combat cuts, chips, chunks and tears for long tread life, even in severe service. The aggressive block radial incorporates four steel belts and an all-steel casing so it can be retreaded for any axle position, according to the company; split-belt construction helps the casing resist cuts and punctures by enveloping debris, which reduces belt damage for longer tire life and enhanced retreadability. To enhance casing life, the FD835 uses computer-designed groove shapes to help prevent trapped stones from pushing into the tread grooves and piercing the belt layer, which can damage belts and expose them to rust.

The new Firestone FD835 is available in the 11R24.5 size with an “H” load rating, and is usable to 65 mph.
