Braking System Gives Lifts Smooth Control

Genie's new traction control drive system for its GS-68 RT series of rough terrain scissorlifts was developed in response to customer requests for increased traction and control. The new drive system allows operators to take on tough environments. To achieve the traction control drive system, Genie added combiner divider valves to divide and isolate hydraulic flow to each wheel. This allows each wheel to work independent of the others, transferring maximum power to the ground even when one or more wheels lose contact. With the new design, should one tire lose contact with the ground, the unit will maintain 75 percent of its power.

The new traction control drive system is designed for gradeability, giving operators access to sites with 35- to 40-percent slope rating. Two drive modes provide control and maneuverability.

“Operators can choose ‘Series Mode’ when they're on flat or level paths, driving at higher speeds and requiring less torque,” says John Norton, Genie product manager. “The ‘Parallel Mode’ is ideal for traveling uphill at slower speeds with maximum torque.”

Also featured is a new hydraulic dynamic braking system, which Norton says gives the operator a consistent, reliable and predictable braking experience, in addition to the standard spring-applied hydraulic release parking brake. “The result is smoother control, particularly on rough terrain, less wear and tear, and greater operator confidence,” says Norton.
