THE PLANNING OF CABLE CAR AT ATTRACTION OF KEPALA SIRING, VILLAGE KEMUMU, DISTRICT ARMAJAYA, NORTH BENGKULU
ABSTRACT
The purpose of this study is to design a
hanging rail plan in attractions Kepala Siring, Village Kemumu, District Arma
Jaya, North Bengkulu Regency which includes the design of the motor, the design
of load-bearing steel wire rope, the design of the drum and pulleys, the
passenger cabin design (gondola), and the design of support poles. The results
showed that (1) the design of the motor consists of (a) the motor specification
includes power based on the load capacity of 14.4 kW, 7.2 kW input power,
efficiency of 83.78%, 1,800 RPM synchronous speed, slip 20.56%, tide moments
1,700,975 Nm, the engine capacity of 8.4 tons/hour, and the number of cycles of
7 cycles/h and (b) the rotational speed of the motor control system with DC
injection current 33.94 A; (2) the design of load-bearing steel wire rope
include (a) a diameter of 8.94 mm, (b) the tension in the steel wire rope or
SWL (Safe Working Load) 12.74 kN, (c)
a heavy burden total work 12 kN, (d) 355.54 kg maximum tensile stress, and (e)
the life of the rope 1 year 5 months; (3) the design of the drum and pulleys
consisting of (a) the circumference of the drum includes a drum style 3,997 N,
the total force on a second drum circumference of 7994 N, the loss on the
bearing 600 N, and total propulsion
efficiency of 1.3% and (b) include a minimum diameter pulleys pulleys that
allowed 250 mm, the amount of curvature that allowed 25 arches, and the minimum
voltage rope pulley wheels 150 kg/cm2; (4) the design of the
passenger cabin (gondola) include (a)
the mass of the aluminum plate for the passenger cabin 4 units of 240 kg and
(b) the strength of the rod hanger cab by 2,599 N; and (5) the design of support
poles consist of (a) poles form of T includes a bending moment of 3600 Nm, normal
force 357,432.35 N, shear stress 89250.26 N/m2 and (b) support poles
include H shape bending moment of 15,000 Nm, normal force 393,204.02 N, and the
shear stress 44625.13 N/m2.
