The type of cable  trolley chosen depends  on the diameter of the biggest  conductors involved and the total conductor width.

The conductor sυpport diameter should  be at least ten times that of the largest conductor. For conductor  widths greater than those indicated in each case ，stages must be added.

E.g.: Assume the following conductor quantities and diameters: 2 x ø 17 mm.; 5 x ø 22 mm.; 2 x ø 24 mm.; 1 x ø 28 mm.; 3 x ø 29 mm. and 1 x ø 36 mm. Total hose width 343 mm.; Recommended cable  trolley  width  350 mm. The largest  conductor diameter  is 36 mm.， therefore the hose support  should be at least 360 mm. in diameter. This means a 400 mm. diameter trolley. The material chosen would be Ref. 2.345-350.

The on-trolley  conductors  support  is divided  into two equal parts and the sum of the width of the conductors may not be divisible by two.

Install conductors on trol1eys as fol1ows:

- Dismount the side plates on both sides of the arms.

- Fit the cables with the largest cross-sections at the centre of the trol1ey and distribute the load evenly on both sides， evening out the lengths.

- Fit the side plates and raise the internal elastic supports around 10 mm. on metallic part.

- Clamp the conductors at the top with the adjusting screws.

The hoses admit correlative clamping of up to 20 mm. diameter difference.

The central elastic support and  the cylindrlcal side  supports mean  there  is no dependence  on one individual hose-carrier. This faci1itates  the bending  of the conductors  at the outlet from the trolley.

Towing wire ropes are most necessary between the cable trolleys closest to the towing trolley.

To calculate hose length， apply a value of 1，1 to 1，25 times the span of the cranes. The smaller the loop and the higher the speed， the higher the coefficient to be applied.

When calculating  the number of cable  trol1eys， the loop height  and the length of the towing wire ropes，use the formula on pages n.O  6 and 7.

Tapered flanged wheels and flat AP wheels with GL lateral rollers are recommended  for all speeds and intense running factors.

GB bottom  rollers  are recommended for systems  subject to side  winds  or inertial stresses，especial1y for systems with a large number of trolleys or trolleys with various stages of conductors.

Different lPN - IPE runways may be fitted by order.
