Travelling gear being parts of machines or mechanical installations for hoists (included in class 7) in particular monorail and double-rail trolleys for lifting gear winches cranes wall-mounted jib cranes pillar jib cranes slewing jib cranes stacking canes gantry cranes overhead traveling cranes single-girder overhead travelling cranes dual-girder overhead travelling cranes The slewing bearing is an essential part of the crane and must be well maintained Over the years the slewing bearing will have some wear and to be able to know if there is a need for changing the slewing bearing it is needed to keep a record of the wear

Slewing Bearing Repairs for the Crane

Messinger Bearings has been offering robust slewing bearing solutions within the crane industry since it received a patent for the innovative cross roller bearing in the late 1930s This bearing style is widely used for crane rotation in boom crawler telescopic and rough terrain cranes for heavy lifting applications due to its versatility

General Technical Information Slewing Bearings SUPPORT STRUCTURES Design of the Support Structure The slewing ring has a limited axial stiffness: the diameter is large compared to the cross section It must be mounted on a machined supporting base ensuring sufficient stiffness with regard to the loads to be transferred

Slewing bearing is one of the most important components of deck crane so It is very important to grasp the condition of slewing bearing periodically in order to prevent unexpected trouble You are kindly requested to pay maximum attention to following items 1 About Rocking test (check of wear amount of slewing bearing)

customer service: Kaydon slewing bearings HS series Similar in size to the RK series Kaydon's HS series slewing ring bearings have rectangular cross sections that provide approximately twice the load capacity (moment ratings up to 139 900 ft-lbs) in the same envelope HS series bearings provide a wide variety of solutions for medium- to heavy-duty applications

The Rollix slewing ring a very robust mechanical part is particularly adapted to these applications Our process control gives the customer a very simple solution to set up the pinion and to save production time Because of the light structure of the crane the Rollix slewing ring bearing is an essential and strategic part Our design matches

Slewing bearings are widely applied in many industries Construction machinery is the initial application of slewing bearings such as earthmoving machinery excavators disintegrators stackers and reclaimers graders compactors dynamic compactors rock drilling machinery road headers and so on So the slewing bearing preventive maintenance is very necessary

To slew means to turn without change of place A slewing bearing or slew[ing] ring (also called a turntable bearing) is a rotational rolling-element bearing that typically supports a heavy but slow-turning or slowly-oscillating loads in combination (axial radial and moment loads) often a horizontal platform such as a conventional crane a swing yarder or the wind-facing platform of a

Effer can satisfy all your needs both if you want a Rack and pinion crane and a slewing bearing crane Effer Rack system ensures a crane rotation angle exceeding 360 that on average is one of the widest in its category On the other hand the slewing ring system allows the crane to

Slewing bearing also called slewing ring bearing is a new type of mechanical component It consists of inner and outer rings and rolling elements The slewing bearing is a large bearing that can withstand comprehensive loads It can withstand large axial and radial loads and overturning moments at
