The Terex Peiner SK 415 (most commonly configured as the SK 415-20) is a heavy-duty, hammerhead-style tower crane originally developed by Peiner and integrated into the Terex Tower Cranes lineup after Terex acquired Peiner in 1998.

Crane Specifications

The crane delivers exceptional reach and hoisting capability, optimizing performance across complex jobsites:

• Maximum Lifting Capacity: 20 metric tons (22 U.S. tons / 44, 050 lbs) when utilizing a 4-part rope configuration.
• Maximum Jib Length: 80 meters (263 feet).
• Tip Load Capacity: 2.3 metric tons (2.5 U.S. tons / 5, 070 lbs) when operating at its maximum 80-meter jib radius.
• Rotation: 360-degree rotating main boom.
• Hoisting Winch System: Outfitted with an SR WB 66–100/4F hoist winch packaged with a 520-meter hoist rope

Design & Operational Features

• The base structure can be anchored directly to a concrete foundation, secured via an undercarriage tower base, or adapted for bottom-climbing and structure-tied configurations.Site Versatility:
• Power Efficiency: Operates natively on a 480v/60hz power supply without needing an external step-up or step-down transformer. 
• Smart Interface: A multi-language, full-color display screen feeds real-time data and system feedback directly to the operator. 
• Weather-Protected Electronics: The cabin platform houses an all-stainless-steel electronics panel. This provides climate and weather protection to ensure consistent electrical system performance.
• EVO15 Operator Cab: Features an ergonomic design that significantly maximizes operator visibility and comfort while integrating simplified joystick controls for smooth hoisting, trolleying, and slewing operations.
