Screwable clamp

For attaching rails of various types to under-rail structures, a clamping bar is used. It allows you to fix the rails on metal or reinforced concrete crane beams, sleepers and half sleepers, by pressing against them. Can be used with or without elastic pad.

Special characteristics

Fasteners that ensure reliable fixation of rails are made of steel, taking into account seismic and temperature operating conditions, sizes and design features of the rails, as well as possible loads.

using bolts, washers and nuts, which, as a rule, are included with the clamping bar.

The pressure bar is characterized by:

– Item weight.

– Permissible side load.

– Bolt tightening torque.

– Possibility of lateral adjustment.

span>

– Type of rail being fixed.

– The thickness of the padding used.

– The width of the sole shelf.

– Maximum side load value.

Properly selected fasteners allow you to evenly fasten the rails along the entire length, properly distributing all loads.

Weld Clamp

Unlike the screwed one, the welded clamping bar provides a more rigid fastening of the rail on metal or reinforced concrete crane beams, sleepers and semi-sleepers, by pressing against them. Weld-on fasteners can be used with elastic pads to provide some cushioning compensation under heavy loads.

Special characteristics

The clamping bar is made of high-strength steel, taking into account seismic and temperature operating conditions, dimensions and design features of the rail , as well as possible loads.

nuts and washers, with the help of which the rail is pre-fixed.

The product is characterized by:

– Weight.

– Permissible side load.

– Bolt tightening torque.

– Side adjustment range.

– Bolt length depending on the bar thickness.

Before buying fasteners, you must carefully study the operating conditions products, characterized by all the features of the fixed rail and the structures to which it will be attached, the magnitude and type of possible loads.

Shims (substrates) for rail fasteners

a rectangular metal plate, not infrequently, with a groove for the sole of the rail. It is an indispensable element that forms high-strength fasteners.

Features and purpose

An underlay placed between a sleeper and a rail serves to:

– Reliably fasten the rail to the sleeper, limiting mutual movement.

– Uniform weight distribution of moving moving mechanisms over sleepers and beams .

– Providing, if necessary, the inclination of the rail track under the desired angle.

without her. At the same time, products without heat treatment must withstand bending, up to 45 degrees, without any damage.

placed under a metal substrate. It allows you to increase the longitudinal stability of the rail and the resistance to dynamic loads that occur on the track, as well as the wear resistance of the entire structure.
