Original Equipment Rebuilds

OEM logos Under the corporate ownership of Konecranes, we are the original equipment manufacturer (OEM) for over 30 crane brands. We are a world-leading supplier of crane parts, and we also supply crane and hoist parts for all other makes and models.

Our knowledge and experience in the crane industry is unmatched. Many of our employees established their background and experience with crane industry leaders like Shepard Niles and P&H, who's crane business' began in 1878 and 1884, respectively.

We can be your one source for all makes and models of crane and hoist parts. If we don't have the part in stock, our engineering and fabrication capabilities can quickly design and manufacture custom solutions, meeting your timetable crane industry and safety requirements - regardless of manufacturer. We also have access to countless original equipment manufacturers' drawings, allowing us to fabricate parts for cranes and hoists no longer manufactured.

Motor Rebuilds That Perform Like New

During tough economic times it’s tempting to sacrifice performance for price. We’re aware of that temptation and that’s exactly why we offer the industry’s finest electrical crane motor rebuilds and rewinds. 

You no longer have to choose between price and performance. Now you can have it all.

Our motor rebuilds perform just like new electrical crane motors, but at a fraction of the cost.

We accomplish that while maintaining OEM integrity to ensure OE specifications and OE performance by using higher quality materials and quality craftsmanship.

Consider these benefits:

  • OEM SPECS: Rebuilt to original P&H manufacturing specifications.
  • P&H MOTOR SPECS: The only repair shop with access to P&H motor specifications and all other Konecranes brand motors
  • GOOD AS NEW: Built in the same manufacturing cells used for building new crane motors.
  • AC & DC MOTORS: Up to 5000 HP or 3,750 kW DC fraction motors (at no load) as well as magnetic brakes.
  • REPLACE DAMAGED SHAFTS: Damaged shafts are replaced with new to ensure precise bearing fit and maintain the overall shaft strength and integrity.
  • CLASS H INSULATION: All motors are electrically tested complete which includes hi-pot tests for voltage and current.  Eddy current brakes are dynamically tested under load using a dynamometer.
  • PROTECTED: All outgoing repairs include an application of rust inhibitor, a protective boot and inclusion of a patented torque nut for brake motors.
  • PROPRIETARY WIRE: Heavy gauge fiberglass over enamel wire for improved varnish retention to withstand mechanical forces and provide higher heat resistance.
  • HIGH EFFICIENCY DESIGN: OE diamond shaped coils offer more efficient end turns than standard round-end turns (mush wound).
  • MAXIMUM DURABILITY: Class H insulation increases temperature tolerances.
  • CORE LOSS TESTING: Eliminates core losses that lead to motor inefficiencies and higher operating temperatures.
  • CRAFTSMANSHIP: Rotor connectors are copper banded, TIG welded, taped and covered for optimal heat resistance.
  • QUALITY PROCESSES: Rotors and stators are dipped multiple times without solvent according to OE specs.

COMPONENT REBUILDS

Sometimes a rebuild is the best solution. If that's the case, our rebuild center has you in mind. In addition to receiving Konecranes quality, you'll realize these benefits:
  • PRICING: Save 40-60% of the price of a typical new replacement
  • RESPONSE: Turn-around is quicker than replacing new
  • WARRANTY: Your rebuilt equipment warranty is the same as a new replacement.
  • OEM SPECS: Equipment is rebuilt to original manufacturer specifications.

TROLLEY REBUILDS

Is your trolley assembly tired and in need of a lot of work? We can strip it down to the frame and install new bearings, seals, friction discs, input shaft and coupling. We replace worn and old holding brakes. The electrical components can be upgraded with new wiring and conduit, new junction box and terminal strip that replaces the old style butt spliced wires.

BRAKE REBUILDS

  • Tear down brake assembly to base
  • Sandblast and check for wear/and or cracks.
  • Replace damaged parts with new.
  • Inspect bases for wear at bearing housings, bearing surfaces and pivot points. 
  • Brush and re-machine as needed.
  • Reassemble with new bearings, busings and hardware.
  • Adjustments set back to factory specs.
  • Brake shoe relining available for most brakes.

HOIST DRUMS

  • Re-grooving and gearing replacement.

ELECTRICAL COMPONENTS

Dedicated to building electrical components to order, our facility in Windsor, Wisconsin can assemble and ship most older or difficult-to-find components within days.  Many in stock items can be out the door in less than 24 hours.
