Modernization

Upgrade Options

Building owners and their management teams recognize the importance of a reliable and efficient elevator system to keep residential or commercial tenants happy.

Despite regular servicing, eventually you need to upgrade your major elevator components or to install a new elevator.

Before a complete modernization is necessary, Delta Elevator can upgrade your major components to extend the life of your device.  

Cab Upgrades

Cosmetic and functional cab modernization to the elevator interiors can include:

Door Upgrades

The operator that drives the elevator doors is prone to wear due to abuse and constant use. On older devices, many parts needed to refurbish the operator are no longer available, so a full replacement is normally required. This type of modernization can include:

Hydraulic Cylinder Replacement

New in-ground hydraulic elevator cylinders are protected from corrosion by encasing the cylinder in PVC. Hydraulic elevators manufactured before 1978 with in-ground cylinders that do not have PVC protection may have undetectable corrosion and deterioration of the bottom portion of the buried cylinder. The cylinder could corrode to the point where there is a risk of rupture and loss of internal system pressure, which could cause the elevator to fall, resulting in serious injury or death of passengers.

The replacement of all such unprotected cylinders must be completed by May 1, 2015 as required by TSSA Code Adoption Document 250/11.

TSSA options to solve this problem:
  1. Remove the existing cylinder and replace it with a new cylinder with a PVC liner
  2. Add a fall protection device (e.g. plunger gripper system)
  3. Add a new down direction over-speed safety device (e.g. under-car safety system)

Advantages and disadvantages of each TSSA option

Hydraulic Pumping

If your elevator requires frequent re-leveling, overheats, or stops erratically at floor levels you may need to fully or partially replace the hydraulic elevator valves and pumping unit. Options for this type of modernization include:

Controller Replacement

Delta stocks a large number of components for older elevators, but when parts are no longer available replacing your obsolete relay-logic based controller with a state-of-the-art control system is probably the next step in modernizing your device.

Delta has been manufacturing its own CSA-approved elevator controller for more than 30 years.  We have the expertise to replace control systems in almost any device from lifts for the physically challenged to high-speed passenger elevators.

Machine Replacement

After a number of years, a traction elevator machine may sustain sufficient degradation to require full or partial replacement. Partial replacement can include conversion from a DC machine to an AC, where the motor is replaced, the MG set is discarded and an AC drive is used instead.
