Elevator Equipment Corporation (EECO)

Mounted directly onto the main jack connection, the Pipe Rupture Valve (PRV) is simple to adjust and extremely reliable in operation. Should an overspeed of the elevator occur, the damped closing of the PRV ensures a quick but smooth slowdown of the car. Slowing to a stop is standard; slowing to a down creep speed is optional. Grooved or NPT straight through line connections enable the customer to attach the PRV to the existing cylinder and pressure line connections in the shortest possible installation time.

EECO Hydraulic Dampener (EHDN) is extremely effective in suppressing the sound and pulsation present in hydraulic elevator systems. The EHDN has a minimum burst pressure of 6000 psi with an ASME A17.1/CSA B44 allowable working pressure of 1200 psi. Unit diameter is 8-5/8” and the length for 2", 2.5", and 3" is 11.75". The 4" outlet unit has a diameter of 10.75" and a length of 13.75".

UV-7B Elevator Control Valve (Valve Size 7, No Coils) The standard EECO UV-7B control valve is designed for applications where pressure requirements are between 50 - 500 psi (3.5 - 34.5 Bars) with flow rates of 75 to 375 GPM (285 - 1419.5 l/min). All EECO valves manufactured since January 2001 contain high temperature Viton seals throughout as a standard feature.

UV-4R Residential Valve (Valve Size 1-KIT COIL S461 110VAC/60 UV5AT) Continuing our tradition of providing the elevator industry with innovative quality products, EECO now offers a small, compact hydraulic elevator control valve for residential, LULA & handicapped applications. The UV-4R has all the performance qualities of larger commercially available hydraulic control valves. Qualities like full leveling in the up and down directions and pressure regulation to maintain constant down speed. Jack ports are provided on both the right and left sides of the valve for easy installation. The UV-4R is capable of handling flow rates of 3 to 35 GPM

EECO Belt Drive (Dry) Power Units are designed with the pump and motor mounted on a sub-base located below the oil reservoir tank and is enclosed with sound isolation panels to limit transmission of noise during operation. The exposed control valve which is located above the tank allows for easy access to adjustments. A removable belt guard is provided to allow access to the pump and motor compartment for maintenance or adjustment of the drive system. Because the pump and motor are connected by means of “v”-belts and sheaves, the pump RPM can be adjusted, by selecting the proper ratio of pump and motor sheaves, to obtain the required flow. This system meets the specifications requiring that the motor and/or pump be mounted outside of the oil reservoir and that the pump and motor compartment be enclosed with sound isolation panels.

A durable ladder designed for elevator pit access, ensuring safety and convenience.

Two stage telescopic jack units (TJR series) consist of upper and lower pistons, a cylinder, and a head bearing and packing gland for each piston. The lower piston is fitted with an additional packing gland at the lower end which rides against the internally honed cylinder. Three stage telescopic jack units (TJ3 series) consist of upper, intermediate, and lower pistons, a cylinder, and a head bearing and packing gland for each piston. The intermediate and lower pistons are fitted with additional packing glands at their lower ends which ride against the internally honed cylinder and lower piston. All telescopic jacks have a synchronous design where all pistons raise and lower at the same speed and at the same time.

ECO can design and manufacture a car sling or platform to any size for any requirement that you may have. From home elevators to commercial passenger elevators and including freight elevators, EECO can handle the job.

EECO Submersible Power Units are designed with the directly connected pump and motor submerged in the oil reservoir. The control valve and muffler are mounted in the tank above the maximum oil level, providing access for valve adjustment.

An automatic swing door designed for elevator entrances, offering smooth and reliable operation.

Single stage jack units (PJR & LJ series) consist of a single piston in a cylinder with head bearing and packing gland at the upper end where the piston collapses into the cylinder. Single stage jacks are designed for "guided" applications only, where the Jack unit is rigidly supported and guided through the use of guide rails and guide shoes and are designed for in-ground and holeless cantilever or dual holeless system applications.
