Fire Engine

To help prevent firefighter back injuries, ladder lift devices are often utilized on fire engines and pumpers. The lift automatically lowers aluminum ladders to a more accessible height for easier removal. A control switch activates two electric actuators that power the lift system.

Warner Linear supplies K2x electric actuators to meet the requirements of this demanding lift application. Units are weather-tight with integral O-ring seals and feature heavy wall rod and extension tube, bi-directional holding brake and Nitrotec® treated end fittings for superior strength and corrosion resistance.

Gear materials are selected for high-load impact and durability. Gear profile is optimized for quiet operation. A unique (patented) screw end bearing guide provides smooth extension operation, high side-load capability and aids in screw re-lubrication.

Other features include a heavy-duty, sealed double ball bearing motor and a mechanical torque limiter for end of stroke and overload protection. High performance synthetic lifetime lubes are used throughout.
