    Abstract: Lift cage for a lift, which is movable upon vertical guide rails by a lifting device, has walls assembled from sheet metal members, a cage ceiling and a cage base. Some of the wall-forming profile members form supporting frame members which together with horizontal base beams, form a cantilever sling for the lift cage. The supporting frame members serve both as the cage body wall elements as well as cage support members.

    Abstract: A hydraulic elevator up direction control system is provided that has a circulating valve connected between the supply and the return of a source that normally supplies pressure to the cylinder of an elevator. The circulating valve is controlled by a computer regulated stepless variable solenoid valve that influences the pilot fluid pressure in the operating chamber of the circulation valve to control the size of the opening of the circulating valve and thereby the volume of fluid passing through the circulating valve. This affects inversely the volume of fluid passing through a fluid flow measuring valve, to the cylinder, to provide selectably variable up speeds of travel facilitating a fast, smooth, accurate ride of the elevator car as it approaches a stopping point relative to an upper floor of a building. Such operation is substantially independent of the system pressure and fluid viscosity. A selectably variable speed down direction control system operates on largely the same principle.

    Abstract: A safety brake device (1) for hydraulic elevators acts by arresting the axial movement of the elevator ram (3) with respect to the main hydraulic cylinder (5) of the elevator. The safety brake (1) utilizes two lever acting brake arms (27) lined with an accretable metal (31), for example annealed copper, as the friction material. When actuated, the brake arms (27) contact the ram (3) circumferentially to slow and stop the falling ram. The lining material (31) is machined inside the brake arms (27) to a diameter slightly less than the diameter of the ram (3) and when actuated, the accretable material (31) on the brake arms (27) contacts the ram (3) with sufficient frictional force to stop the downward motion of the ram (3). The safety brake (1) may be actuated by loss of hydraulic pressure, by an electronic signal from a hydraulic pressure detector, by down overspeed or by an uncontrolled down motion detector. In the case of the hydraulic pressure loss, reapplication of normal pressure in the hydraulic cylinder (5) will automatically reset the brake (1). The safety brake device (1) can also be configured for use as a safety brake on other hydraulic or pneumatic cylinders or for use as a safety brake on cable-actuated traction elevators.

In addition to a normal diverting pulley mounted on the top end of the piston of the hoisting cylinder, the arrangement includes an additional diverting pulley placed at the bottom end of the cylinder. The first ends of the elevator ropes are fixed to a rope anchorage in the car frame of the elevator, from where the ropes are passed over the diverting pulley on the top end of the piston to the additional diverting pulley, from which additional diverting pulley the ropes are further passed to an adapter moving with the top end of the piston, with the second ends of the ropes being attached to the adapter.

    Abstract: A twin post, telescoping jack hydraulic elevator system has a pair of dynamic sensors to determine when the jacks are out of synchronization, by determining any relative differences in height between the two intermediate cylinders. The elevator also includes static sensors to determine if one or both intermediate cylinders are more than a predetermined distance away from their normal positions when the car is stopped at each floor. The controller actuates a resynchronization if the distance between the intermediate jacks exceeds a first threshold, and shuts down the elevator if the distance exceeds a second threshold or if resynchronization demands are issued too often. Preferably, the static sensors are positioned to detect the seal housing at the top of the intermediate cylinder, which projects outwardly from the cylinder.

    Abstract: An obstruction sensing guard for use on a vertically-moving lift table for sensing an obstruction and stopping movement of the lift table in response thereto. The guard includes a sensor bar extending vertically below and generally along the table outer perimeter. The sensor bar is hung below the table via flexible connections that allow both horizontal and vertical movement of the sensor bar with respect to the table. The sensor bar is easily assembled with connecting boots at each corner and elongate beams extending therebetween and connected to the boots. Electric contact switches are provided on the sensor bar and are actuated when the sensor bar is moved. The contact switches are retained on the sensor bar with a switch clip that frictionally engages the sensor bar.

    Abstract: In the energy conservation type hydraulic elevator, a load carrying elevator and a balancing elevator are each provided on a respective hydraulic cylinder. The hydraulic cylinders are connected to one another by a fluid circuit. The balancing elevator is weighted so as to minimize the power input required of a hydraulic pump in the fluid circuit. In the speed control method of a hydraulic elevator, a negative pressure is first produced in a fluid path connecting a hydraulic pump and a control valve so that oil is drawn into the fluid flow path from an oil tank by way of a nonreturn valve. Descent of the elevator is then permitted to start by opening a control valve, allowing hydraulic fluid to flow from a cylinder, by way of a hydraulic pump, to an oil tank. The hydraulic pump and a motor rotate with the hydraulic fluid, and the motor is rotated at a synchronous number of revolutions by switching on an inverter power source when the number of revolutions has reached the synchronous number of revolutions of the motor.

    Abstract: A hydraulic elevator pressure relief valve is activated if a pilot valve disposed therein senses an excessive pressure build up within a hydraulic elevator system. The pilot valve opens once excess fluid pressure force is detected. A main piston then facilitates communication between a solenoid valve disposed within the valving system and the drain pressure thereby closing a check valve and thus stopping an elevator car from further movement. The main piston further ports the excess fluid pressure force from the system to drain pressure, thus stabilizing the fluid pressure force therein.
