ABSTRACT:
An elevator hydraulic tank is provided with shaped sides which increase the rigidity and heat dissipating ability of the tank. The shaped sides of the tank may be corrugated. A hydraulic machine is mounted on the underside of the tank lid so that maintenance of the machine does not require draining of the tank. The shaped sides are enclosed by an outer shell which further minimizes noise emanating from the tank.
