Giant Passenger Elevator Construction – Traction - Canton Elevator

 

This summer, we had the opportunity to work with one of our great school customers to install a giant freight passenger traction elevator at their new building.  This was a specialty application that required a unique sized elevator.  Going through the process, it is always cool to see start to finish as the building starts going up and then progresses to completion.

Package provider – Canton Elevator

Controller – Motion Control Engineering

Machine – Hollister Whitney

Door operator – GAL

Doors – Columbia

Fixtures – Innovation Industries

2 years in the making – From the start of discussion to the end of the project was about 2 years.  We went through design, bidding, procurement and installation.  Alex in our office went through several iterations of concept before the design team took the elevator out to bid.  We were fortunate enough to be awarded the project and we started working with the GC Gilbane on the contract particulars.  Once we ironed out the contract details, we were on to ordering the elevator through Canton Elevator, who also helped design the elevator for the school's design team.  Once delivered, we started our elevator installation work onsite!

Challenges – Since this was a unique installation we had some challenges on the supplier side. Canton was always responsive and got us squared away quickly so we could keep moving. Big shout out to California Duane! Since this was a unique installation, we also had challenges with our design team. Thankfully everyone on the team was great to work with to get through each challenge as it came up.

Team work– From the truck driver to the engineers to the billing department to the assist when needed, 18 Colley Elevator employees where involved in the project and we had tremendous team work on it.  Thank you everyone; without you we would not have had such a successful delivery[on time]!  Team work with our supplier, team work with our design team, team work with our GC/CM and team work with the school system.  Special commendation for the project team who did the time and heavy lifting, thanks guys!!!  You did great!

Schindler 330 Inverted Piston Roped Hydraulic Elevators MCP Update Notice

In the second of our series in how to maintain an elevator, we'll discuss roped hydraulic pistons. We recently got a few emails and calls from our customers who have Schindler 330 inverted roped hydraulic pistons. They said they had received notices from the manufacturer on proper care.

We have been incorporating these checks for years, however, it is a good reminder that it needs to happen and these documents should go into the MCP(maintenance control plan). If you do not follow these procedures, you will have chronic issues with leaky packings and possibly other issues.

What is a maintenance control plan? The maintenance control plan is the plan that the contractor has with the building to maintain the elevator system. It should give the owner, mechanic, inspector and anyone else involved a run down on how the elevator is maintained. It should be similar to a manual for your car/automobile. It will tell you the following:

 

1. Equipment age, condition and accumulated wear

2. Design and inherent quality of the equipment

3. Usage

4. Environmental conditions

5. Improved technology

6. Manufacturers' recommendations for any SIL rated devices or circuits

7. Cleaning, lubrication and adjusting schedule

8. Tests on the equipment & schedules per A17.1.8.6

9. Code required written procedures for maintenance, testing and inspections

10. Maintenance records

11. Procedures for testing

12. Unique product specific procedures required to test equipment

13. Procedures on how to maintain the specific elevator

For a list of all the requirements look at A17.1 8.6.1.2.1

Information particular to the Schindler 330a elevators are as follow.

General inspection

1.1 – Visually inspect the jack synchronization ropes for any damage or excessive wear

 
1.2 - Visually inspect the synchronization rope sheaves for any damage

1.3 - Confirm the synchronization rope sheaves rotate without noise

Check synchronization rope lubrication

2.1 – Verify jack synchronization rope(s) has light lubrication present when checked with a clean cloth. If lubrication is required, the synchronization rope shall be lubricated with a 34-38 SSU light vicosity spindle oil

Check synchronization rope tension; adjust tension if required

3.1 – Run car up until the car is at its stop ring, check the jack synchronization deflection by hand. All rope adjustment must be made while the jack is fully extended.

3.2 – Verify synchronization rope(s)

• Has 1 Inch (25mm) deflection or less
• Does not have a slack wire rope condition present
•  All have equal tensions, if more than jack synchronization rope is present.

If tensioning of one or more synchronization ropes is required, then adjust tension according to steps 3.3 through 3.5. If no tension adjustment is required, then skip to step 4.

3.3 - Set up top nut on the eye bolt toward its end and the bottom nut towards the eye to start with maximum adjustment upward. Loosen the rope clamps and pull the end of the rope to add as much tension as possible. Tighten the rope clamps and now tighten up on the top nut o the eye until the rope has less than 1 inch of deflection. Run the bottom nut up tight to the underside of the synch eam to lock in this adjustment. If the ropes are too close to the car, realign the eyebolts toward the back of the car. DO NOT bend eyebolts, as this could recreate an unsafe condition.

3.4 – Repeat this for the other rope (if present) setting them or roughly equal deflection.

3.5 – Run the car down off the stop ring and you will notice that the car adds additional tension to the ropes.

4.1 – Check the wire rope diameter. The nominal size of each rope is .25 inch. Ropes must be replaced when the rope diameter measured at any point is less than .242 inch, reference table ASME A17.6 A7.6 1.10.3-1.

If replacement of synchronization ropes is required, use Schindler parts identified in the Schindler Renewal Parts Manual section 10C7 (or equivalent)
