Vector Lifting has introduced a new range of conveyor take up winches incorporating several additional safety features to ensure simple installation and operation onsite.

The additional safety features in the new conveyor take up winches include: ratchet and pawl for engaged and disengaged limit with interlocking; pawl fitted with a shear pin; shredder cover and pitch cover design to protect winch and control panel from falling objects; cam limit switch for setting up and lowering limits; rope overlay limit to prevent doubling up of the rope during hoisting; lifting eyes to assist with transport and installation of winches; stainless steel components to prevent corrosion; final up limit to protect winch and structure; all functions interlocked to prevent incorrect operation; winch frame to house all electrical cabling, preventing damage and entanglement; transport frames to assist with transporting the winches as a whole unit; and load cells to prevent overloading of the winch.

Vector Lifting’s take up winches have been designed to perform all tasks with safety in mind. The equipment is designed and manufactured by Vector Lifting to applicable Australian Standards, including AS4024.2014 ‘Safety of Machinery’. This standard is used as the basis for Design Risk Assessment when redeveloping existing products or designing new products. The risk assessment is established and periodically reviewed throughout both the design and manufacturing stages to minimise risk to the health and safety of people associated with the machine, ensuring safe installation and operation.

The new conveyor take-up winches have been developed by Vector Lifting with particular consideration to ensuring simple and safe operation as well as designing a robust and efficient product that satisfies the requirements of the equipment’s specific duty and the environment in which it is operated.

A brief summary is provided below, listing the major areas of winch design considered in past AS4024 Risk Assessments. Each new product is reassessed to ensure that the conditions and requirements of the new site and operating environment are considered and all client-specific prerequisites applied.

Design of Controls, Guarding and Interlocks are critical areas in the interaction between operators and winches in order to provide safe and efficient equipment.

Key features that have been included in the winch design through risk assessments and design workshops include rope overlay detection; winch drum guarding with mesh screen inspection points; electrical overloads, phase rotation indication and phase failure relays; final up limit; emergency stop button; hold to run controls; placement of rotating and moving components in relation to personnel control and access points; and clear warning and instruction signage positioned on the winch.

Relevant standards used: AS1418, AS1554, AS1710, AS3000, AS3008, AS3569, AS4024, ISO 9001:2008.
