Design, Development and Analysis of Toggle Lever Caliper Cable Trolley Brake for Fail Safe Operation
نویسندگان
چکیده
Present cable trolley brakes used in material transfer or overhead trolley transport systems uses twin shoe caliper brakes operated by solenoid. These brakes are not fail safe, means that slip occurs between cable and brake caliper. Sometimes overloading leads to wear of brake shoe material. The failure of brake system may increase the chances to loss of life of occupant. These conventional caliper brakes are replaced by self-locking toggle lever operated caliper brakes. More over change in friction material as copper wire reinforced brake liner material with better coefficient of friction, better heat dissipation ability make the brake fail safe in operation.

Design and Modification of One Arm Driven Manual Hemiplegic Wheelchair
This paper presents design modification to the existing standard wheelchair by incorporating an improved propulsion system and also braking and tilting systems that allow its full control with only one hand. The proposed design has the propulsion system with a chain drive powered through a four-bar linkage driven by the main handle. The desired direction of motion is obtained by moving the leve...
متن کاملDesign of Sliding Mode Controller for the 2D Motion of an Overhead Crane with Varying Cable Length
Overhead cranes are under-actuated systems. They have three outputs that need to be controlled, consisting of cargo swing angle, trolley displacement, and suspended cable length, but only two actuators: cargo lifting and trolley driving forces. The main objective of this study is to design a robust controller for an overhead crane that transfers cargo from point to point as fast as possible and...
متن کاملInvestigation of brake squeal and the influence of the abutment faces
This paper demonstrates the influence of the trailing end of the piston, or inboard, pad on the propensity of a brake to generate audible squeal. The unique technique was employed to measure the dynamic centre of pressure at the pad/disc interface during a normal braking operation. This novel technique uses an embedded pressure sensitive film within the pad. The paper also presents the co-plana...

متن کاملHydraulic anti-lock, anti-skid braking system using fuzzy controller
To maintain the stability trajectory of vehicles under critical driving conditions, anti lock-anti skid controllers, consisting of four anti-lock sub-controllers for each wheel and two anti-skid sub-controllers for left and right pair wheels have been separately designed. Wheel and body systems have been simulated with seven degrees of freedom to evaluate the proper functioning of controllers. ...
