| With safety becoming an increasingly important factor in the design and manufacture of equipment, it has become necessary to add a professional brake to many critical machine functions. In response to that concern, White Drive Products offers the BK10 Series brake. All internal components, including industrial roller bearings, brake disks, springs and professional seals were chosen for maximum durability. To further extend the life of the unit and reduce noise, all internal components run in an oil bath. Two brake release ports are also provided to simplify plumbing and bleeding of the brake release circuit during installation. All of these features combine to make the BK10 Series brake the top choice for any static brake application requiring 10,000 lb-in of holding torque. |

| Spring applied safety brakes offer high operational security for all applications, protecting personnel, machines and equipment, reliably braking for positioning or holding duties or for sudden machine stops for emergency OFF or power failure. We have developed as the technology leader in the field of safety brakes by developing optimised solutions for a wide product range. |

The SITEMA Safety Brake type KSP is designed to hold a vertical moved mass in one direction (against gravity). The holding is done on a round shaft. This could be an already existing cylinder rod or a separate rod. The Safety Catcher can also be used to catch the falling load in case of an emergency-stop. The holding force is relatively big in one direction (downwards) and in the other direction (upwards) relatively small.
Safety brakes are already used in the following applications
- vertical or diagonal equipment tool axes
- vertical axes of loaders

The following calipers give various examples of the "spring applied, hydraulically released" professional brake range. Often described as "Safety brakes" these units are typically installed and controlled as automatic protection devices on such machines as escalators, elevators, suppliers of conveyors, mine winders and cranes.
Options include; adjustable torque control, automatic pad wear adjustment, monitoring devices, discs, hubs, hydraulic power supplies manufacturers and pedestal mounting kits.

The following spring applied, pneumatically released brakes are but a small example of the choices available. These brakes can be conveniently hooked up to shop air supplies or powered by seperate compressers. Most include convenient features such as; automatic pad wear adjustment, torque adjustment, quick change pads, modular design and easy maintenance.

Safety brake for Elevators - Elevation Line
The ELEVATION LINE is comprised of DC operated spring applied single-disc and double disc brakes which comply with the requirements of the European standard EN 81 (safety requirements to be observed in the construction and installation of elevators). Owing to the patented safety concept, the usual checks concerning the double-circuit system of spring-applied brakes can be omitted during the technical approval of the elevators.
The brake is ideally suited for use in space restricted environments where compact systems comprising of a motor, gearbox and brake are required. The ELEVATION LINE is preferably used in the field of professional elevator construction, but it is also ideal for other applications characterised by stringent requirements in terms of brake safety.

Twiflex VMS-DP Mill Professional brake Stand. One of four units supplied to Metso Minerals for use at the Telfer Mine, Australia. The two units combined produce 16Million NM of brake torque!
The VMS-DP Mill Brake brakes will be installed on SAG (semi-autogenous grinding) Mills used for the extraction of copper and gold from virgin rock. Fresh ore is continually conveyed into the mills that are pre-charged with various sizes of steel professional balls, crushing the rock when the mill rotates. The ore is crushed until small enough to pass through the openings in the discharge professional grates. The material is then conveyed to a secondary Ball grinder for fine grinding.
The brakes which are used for emer-gency stopping and holding have been designed specifically for this application and will be the largest that Twiflex has ever manufactured. The VMS-DP caliper is approximately the size of an office desk and weighs approximately 2 metric tonnes. Each brake produces 768kN of braking force, 4-6 calipers provide braking to each mill flange.
