Application

Application Overview

Specifications

The Flexible Guide Clamp Safety, Type B1 (Northern) is designed for elevator application. The safety uses a pair of stationary wedges loaded by disc springs and a set of moveable wedges. The springs apply a constant, uniform force, through the stationary wedges to the moveable wedges, stopping the car by means of the friction between the moveable wedges and guide rails. This results in the car coming to a gradual controlled stop.

Information and Specifications are based upon other standard ThyssenKrupp equipment such as buffers, roller guides, and counterweight frames. The dimensions could change with custom safeties or equipment manufactured by others.

The Flexible Guide Clamp Safety, Type B1 (Northern) works on the principle of a pre-determined and gradually applied force to the side surfaces of the rails.

S S S S

The Flexible Guide Clamp Safety, Type B1 is limited for use with all of the following: S Maximum Speed: 500 fpm

The magnitude of the braking action is dependent on: S Type of disc springs S Quantity of disc springs and their arrangement S Spring stroke: Spring stroke is dependent on wedge movement which is controlled by mechanical stops calibrated at the Factory. A seal is provided to prevent adjustment changes since the safeties are built for a specific application as indicated on the safety data plate.

Maximum Gross Load: 11,000 lbs. Rail Size: 15#, non-lubricated Net Travel: 300 feet or less Governor Sheave Diameter: 12I

S Governor Rope: 3/8I S Governor Pull Through: 200 lbs. minimum S Guides: 8I Roller Other specifications are listed in Table 1.

Certifications The Flexible Guide Clamp Safety, Type B1 (Northern) has passed different free fall tests (drop tests) up to the maximum listed ratings in compliance with the requirements of the ASME A17.1 Safety code for Elevators and are certified with the State of California.

Governor rope connections are available in either right or left hand (front or rear), depending on the quadrant location of the governor. Safeties are tested and factory preset based on individual job specifications or requirements.

Some modifications apply to meet local Authority / Code requirements. Successful tests have been conducted in accordance to AS 1735.2. Australian Standard and Certification has been granted by the Work Cover Authority (Reference file # 20182lLS12). Model #

Safety Test The Flexible Guide Clamp Safety, Type B1 (Northern) safety is jig assembled, adjusted, and then sealed at the factory. No factory seal(s) or setting(s) should be changed in the field without first consulting with the Field Engineering Department for written instruction on possible re−adjustment(s).

Pre-Test Inspection Failure to check any of the following could result in unequal engagement, or complete failure of the safety to engage.

8

Before a safety test is conducted, check the following: S that the rails are free of any oil or protective coatings. S that the holding spring is compressed to 141/4I in length when the safety is in the reset position. See Figure 1. This sets the force the governor must exert on the safety arm at about 69 lbs. S that all dowel pins are in place, and tight. S that all cotter pins are in place and split both sides. S the length of the link rod. This controls the synchronization of the two sets of moving wedges. The link rod must be straight, without kinks or other damage. Replace any damaged link rod. See Figure 1.

THYSSENKRUPP ELEVATOR

Troubleshooting

S that the locknuts on the link rod yoke clevis (both ends) are tight.

Testing The Safety

S that the link rod, link rod lever, and the wedge linkage lever are NOT obstructed by any devices mounted underneath the car. See Figure 1.

1. Test the safety. Refer to the appropriate Control System manual for procedure.

S the gap between the moving wedges when they first meet the rail and their respective stop bolts. See Figure 2. S freedom of movement of shafts, levers, wedges, and roller cages. Move the safety arm up and down by hand to check. S that all parts are free of any debris and are lubricated as outlined under Maintenance. S the safety switch and adjust, if necessary, so that the switch is closed when the actuating plunger is resting against the flat of the safety switch cam. See Figure 2.

2. During the test, after the moving wedges have engaged the rail, check that the wedges are against the stop bolts. This indicates the safety was fully engaged. The following step must be done before the elevator is returned to or placed into operation. 3. After the safety has been tested, inspect the safety to ensure that it has reset fully, no parts have been broken or damaged.

Maintenance Regular maintenance checks and servicing is a must to ensure that the safety is ready to operate when required.

2. At each lubricating interval, inspect all parts of the safety as follows:

1. Check all pivot shafts for freedom of movement and lubricate per Table 2.

S Examine all actuating parts. Inspect for free movement. Make certain parts are not painted, rusted, damaged or broken. Clean or replace as necessary.
