Wall climbing elevator systems include a load compartment and a carriage assembly. The carriage assembly includes a set of wheels configured to frictionally engage with a wall surface of a building and at least one suction system configured to aerodynamically adhere the carriage assembly and the load compartment to the wall surface. Each suction system of the at least one suction system includes a skirt assembly defining a suction chamber between the carriage assembly and the wall surface and a fan assembly for generating a low pressure within the suction chamber to generate an aerodynamic adhesion to secure the carriage assembly and the load compartment to the wall surface.

The disclosure relates to a device and method for installing and adjusting pressure of a roller guide shoe, and an elevator system. The device comprises: a bracket, installed on a car frame upright of an elevator car; a positioning portion, installed on the bracket and operatively having a first state in which the positioning portion fixes a positioning of the car frame upright relative to an elevator guide rail to define a reference for installing the roller guide shoe to the car frame upright, and a second state in which the positioning portion releases the positioning; and a pressure adjusting portion, comprising a contact member installed on the bracket, and a mating member installed at a preset position on the elevator guide rail and located outside a running trajectory of the roller guide shoe on the elevator guide rail, wherein when the elevator car is driven to run close to the preset position and stops, the contact member comes into pressure contact with the mating member to at least reduce a contact pressure between the roller guide shoe and the elevator guide rail.

An elevator power system for an elevator system, the elevator power system including an inverter configured to provide drive signals to a motor to impart motion to an elevator car; a power controller configured to generate control signals used to control the inverter; an isolation module positioned between the power controller and the inverter, the isolation module configured to prevent the control signals from reaching the inverter in response to a safe torque off mode of the elevator system.

A machine-room-less elevator traction system and elevator equipment are disclosed. The machine-room-less elevator traction system comprises: a power device comprising at least a first traction part and a second traction part which are arranged at an upper portion of an elevator hoistway, a guiding device arranged on an elevator car, and a tension device comprising at least a first tension member and a second tension member, wherein the first tension member is in drive connection with the first traction part, with a first end of the first tension member connected to an elevator counterweight, and a second end of the first tension member fixed to the upper portion of the elevator hoistway after passing through the guiding device; the second tension member is in drive connection with the second traction part, with a first end of the second tension member connected to the elevator counterweight, and a second end of the second tension member fixed to the upper portion of the elevator hoistway after passing through the guiding device; wherein the power device is connected to an elevator controller which controls operation of the power device such that the first and second tension members are driven by the first and second traction parts respectively to drive the elevator car and the elevator counterweight to move within the elevator hoistway.
