“Gurat Hill”, the official distributor of SIGMA Elevator lifting equipment in Turkmenistan, offers customers an extended 5-year warranty on all products supplied. This warranty significantly exceeds industry-standard warranties and covers all elevator components, from mechanisms to electronic control systems.

SIGMA Elevator's strict manufacturing standards underpin this extended warranty. Products are tested in the company's own accredited laboratory, recognized by the China National Accreditation Service (CNAS) since 2004. Test results are accepted in more than 80 countries, including the United States, Germany, Japan, and France.

The manufacturer applies requirements that exceed generally accepted standards. For example, the door lock reliability test is 2 million cycles, compared to the industry standard of 1 million, and the buttons withstand 3 million presses. The laboratory covers over 200 types of tests and monitors over 90% of the equipment components.

Strict testing standards ensure reliability.

One of SIGMA Elevator's key competitive advantages is its use of testing standards that exceed generally accepted industry norms. Each piece of equipment undergoes multi-level testing:

Elevator Components:

• Pendulum Impact Test: OTIS standard 1020 mm vs. industry standard 800 mm

• Door Lock Reliability Test: 2 million cycles (requirement: 1 million)

• Light Curtain Life Test: 1 million cycles (not specified in the standard)

• Door System Life Test: 3 million cycles vs. industry standard

• Door Roller Life Test: 2 million cycles

• Keypad Resistance Test: 3 million presses

Escalator components:

• Handrail life test: 3000 hours (not specified by EN 115)

• Comb brake test: 5000 N (not required by the standard)

• Dynamic step load test: 20 million cycles

• Step roller life test: 5000 hours versus 250 hours required by the standard

• Salt fog resistance test: 480 hours (not specified)

• Auxiliary brake test: 100 cycles

Environmental and climate testing:

• Controller test under harsh environmental conditions: range from -10 to +70°C

• IP test: door motors are IP65 rated

• Dust test: 6 kg/m³ standard versus 2 kg/m³ standard

• Thermal cycle test: range from -40 to +125°C

This level of quality control in production directly determines the long-term trouble-free operation of the equipment and forms the basis for providing extended warranties.

“Gurat Hill” provides a full range of services, from consultation and installation to maintenance. The warranty includes free repair of manufacturing defects, replacement of faulty parts, and prompt service in case of malfunction.
