BM series pendulum friction coefficient tester
1. BM-III pendulum instrument is developed according to JTG E60-2008, JTG E42-2005, JTJ 052-2000. The BM-III pendulum instrument has all the functions of the BM-II pendulum instrument, and can also be used as the coarse aggregate buffing value test in JTG E42-2005 (the type II pendulum meter does not have this function)
Description:
With the development of transportation, the anti-skid problems of roads, urban roads and airport runways have attracted the attention of relevant departments. The pendulum friction coefficient tester (referred to as pendulum instrument) is an instrument for measuring the friction coefficient of road surface, airport runway, marking paint. It is also possible to pass the measurement of the typical road friction coefficient as one of the basis for determining the formulation of the seed-preserving tire. The instrument is easy to debug and easy to operate. It has less impact on traffic during testing, and the data is stable, and can be used indoors and outdoors.
P
rinciple:
The pendulum instrument is a power pendulum impact type instrument. It is based on the basic principle that “the energy loss of the pendulum is equal to the work done when the rubber piece at the end of the swing arm slides across the road surface and overcomes the friction of the road surface”.

1.
Base:
It consists of T-shaped legs, leveling screws and leveling bubbles, which regulates the instrument.
2.
Column:
It consists of a column, a lifting mechanism, a guide rod and an instrument handle. Used to raise and lower the position of the oscillating head.
3.
Release switch:
The switch mounted on the cantilever is used to maintain the horizontal position of the swing lever and release the swing lever.
4,
swing head:
consists of a fastening handle, swing shaft, steering knuckle, bearing, etc., from the connection pendulum, fixed position, to ensure the free swing in the swing plane.
5.
The display system
consists of a pointer, a felt ring, a flange, a fastening nut and a dial. The pointer can directly indicate the value of the friction coefficient.
6.
Pendulum:
consists of upper and lower joints, pendulum rods, springs, levers, lifting handles, outer casings, sliding blocks and rubber sheets. It has a specified torque for the center of the swing, a predetermined pressure on the road surface, and a balance of the front and rear, left and right moments. It is a measure of the friction coefficient of the road surface.
Main technical specifications:
1. Swinging torque: 615000g.mm
Among them, the weight of the pendulum: 1500±30g
Swing weight: 410±5mm
2. Positive static pressure of rubber sheet on the road surface: 2263g
3. The number of times the swing head is tilted 5° freely to the swing stop, not less than 70 times.
4. The outer edge of the rubber sheet is 510mm away from the center of the swing.
5. The total weight of the instrument is about 26Kg.
6, Dimensions: 700x340x740mm
