The basic design features a moveable core, either a solid-wire or a wire-rope cable that's free to travel axially inside an outer casing or conduit.
Expertly Engineered Cables
Whatever market your product performs in, you need to know your cable assembly is in good hands; Drallim Industries shares with you over 50 years of Engineering and Manufacturing experience. It is our aim to provide you with the perfect control solution to suit your, often unique, requirements.
Our Cable Design
Our design team are here to work with you through the development of your cable if you require, or we could simply manufacture to your drawing and / or specifications; whether the part is unique or has been discontinued. Kit car building, classic car or aircraft renovators will all benefit from our Copy Cat service.
Our pledge at Drallim Industries Ltd is to provide the ultimate service to our clients, providing high-quality cables and rods that conform to the specifications as set out by commercial, military and aerospace regulations, thus completely satisfying the needs and requirements of all our clients.
Quality Managment System
Drallim operates a full Quality Management System across all three divisions of the company and has been registered as an ISO9001 company since 1994. We are approved for Civil Aerospace work, with the European Aviation Safety Agency, enabling us to release both Production of new parts and appliances and Maintenance of our products. In 2010, we achieved the AS9100 approval for our Aerospace division, successfully upgrading to revision C of that standard last year.
Mechanical Control Cables
Mechanical control cables provide a simple, lightweight, economical, and reliable way to actuate throttles, latches and a thousand other mechanisms. They're widely used in furniture, vehicles, lawn mowers, and medical devices, as well as seats in cars and planes. They impact our everyday life. The basic design features a moveable core, either a solid wire or a wire-rope cable that's free to travel axially inside an outer casing or conduit. Actuation of a lever at one end of the cable assembly will produce an output force and motion at the other end. The mechanical cable is designed under two criteria, Push-Pull or Pull-Pull cables.
Push-Pull and Pull-Pull cables
Push-Pull and Pull-Pull cables are used on a wide variety of applications. The function of the unit being controlled and the routeing of the cable need to be analysed before selecting the correct cable. All the external variables need to be addressed, Variables such as load, friction, routeing, stretch, length, bends (How many and their radius), temperature, environment and contaminants. Every one of the could affect the operation of the cable.
Push-Pull cables are called such because they use the actuation force in both the push and the pull modes. Solid core inners or solid core cables (stiffer cable) would best suit this application however the bend radius would be larger. Push-Pull cables have a greater capacity in the tension (Pull) mode than in the compression (Push) mode. Loads in the compression mode should be around 50% of those in the tension mode. Reducing the push load minimises a core's tendency to displace the conduit and, reduces the potential for the unsupported core outside the conduit to kink, bend, or distort.
Pull-Pull cables are in most cases more flexible and are used in the tension (Pull) mode. The design has an integral return spring maintaining the load on the cable returning it to the standby position. This spring allows the use of flexible cables allowing tighter radius. Maximum working loads should be minimum breaking load of the core plus a built-in safety factor.
