Pivot bearings - Import export

Korzonek Klarwerkstechnik, METZEN’s sewage treatment branch, has been a competent and trusted sewage engineering partner to local authorities, wastewater companies and industrials for over 30 years. We design and manufacture custom spare parts for all scrapers and refurbish them to guarantee their long service life. Longitudinal scraper chassis Circular scraper chassis Drive wheel with direct drive for circular scrapers Rack-and-pinion drive chassis Rack-and-pinion rails Longitudinal scraper chassis with stabilising cross beam and rail drive Rack-and-pinion drive with rail impeller Bolt rail for rack-and-pinion drive Rail longitudinal scraper chassis with synchronously controlled drive Pivot bearings and slip ring systems We manufacture and assemble pivot bearings and slip ring systems with hose swivel joints or without hose access. Scraping blades for longitudinal and circular scrapers We manufacture and assemble single and multi-piece scraping blades.

Bulk handling of any kind in sea and inland ports or storage facilities. For ship-to-ship, ship-to-storage/wagon/silo handling. For various types of crane with control systems designed for hydraulic motor grab systems. Technical design Designed as a discharge and ship unloading grab with retracted pivot bearings for easy gripping under the ship’s gangway Optimisation of crane load capacity thanks to its lightweight design which can hold maximum loads Grab drive: Vertical electrohydraulic drive unit with high-pressure pump Closing and opening movements are controlled through clockwise or counter clockwise rotation of the electric motor (turn control). The electric motor is only switched on whilst the closing and opening movement is being performed. Grab connection bearing: Re-greaseable steel bushing bearing Stable, torsion-resistant design using direct cylinder linkage

Bulk handling of any kind in sea and inland ports or storage facilities. The compact alternative to the MZG type grab for ship-to-ship, ship-to-storage/wagon/silo handling. For various types of crane with control systems designed for hydraulic motor grab systems. Technical design Designed as a discharge and ship unloading grab with retracted pivot bearings for easy grab under the ship’s gangway Optimisation of crane load capacity thanks to its lightweight design which can hold maximum loads Self-locking grab suspension for crane hooks Grab drive: Horizontal electrohydraulic drive unit with high-pressure pump Closing and opening movements are controlled through clockwise or counter clockwise rotation of the electric motor (turn control). The electric motor is only switched on whilst the closing and opening movement is being performed. Grab shells: Material: S355J2+N Grab connection bearing: re-greaseable, robust steel bushing bearing Small grab dimensions thanks

Slag handling in waste incineration plants or incineration plants of any kind. For various types of cranes with internal or external holding cables. Technical design Designed as a discharge grab with stable, retracted pivot bearings Optimisation of crane load capacity thanks to its lightweight design which can hold maximum loads Self-locking grab suspension for crane hooks Grab drive: Vertical electrohydraulic drive unit with high-pressure pump Closing and opening movements are controlled through clockwise or counter clockwise rotation of the electric motor (turn control). The electric motor is only switched on whilst the closing and opening movement is being performed. Closing and opening movements controlled by directly connected hydraulic cylinders, with stable piston rod protection Grab connection bearing Re-greaseable, robust steel bushing bearing KRÖGER MAINTENANCE-FREE bearing system Grab shells: Shell design adapted to material flow Toothed segment drive Material: S355J2+N

Underwater gravel and sand extraction using dredgers with 2-cable or 4-cable winches. Suitable for use in all river and lake dredging areas with difficult ground conditions and deep dredging depths. Technical design MAINTENANCE-FREE design, which benefits both the environment and your profitability High load capacity thanks to its lightweight design Robust, torsion-resistant grab design for maximum loads Grab shells made of wear-resistant fine-grain steel Tooth tips are interchangeable depending on ground conditions KROGER MAINTENANCE-FREE bearing system in the shell pivots and cylinder rod bearings KROGER power unit is easy to service, the crosshead engine is separate from the hydraulic tank, hydraulic units are in the tank Environmentally friendly hydraulic fluid using organic oil
