We can create mobile platforms on request. Discuss your mobile platform requirements with us. For mobile platforms we generally use GRP construction profiles manufactured in accordance with EN 13706 / E23. This ensures that the platform has a minimum loadbearing capacity. These GRP construction profiles typically have an isopolyester resin matrix. For structures that are exposed to higher chemical stress, we can also use profiles with a vinyl ester resin matrix. If profiles need to be connected with angle brackets, we generally use V4A stainless steel connectors. We do not use short GRP remnants for such connections because they are not sturdy enough.

The elevator emergency stop device is a device that automatically operates and safely stops the elevator when an emergency occurs inside or outside the elevator. This device is an essential part to protect the safety of life and property, and is one of the devices that must be installed compulsorily in the elevator safety regulations. Generally, the elevator emergency stop device is attached to the elevator cable, and operates on the principle of automatically stopping the elevator by detecting when the cable moves at a rapid speed. This is controlled by a control device installed inside the elevator, which stops the elevator and opens the door to allow passengers to escape. Donggwang Sau provides safe and reliable elevator emergency stop devices using the latest technology and equipment, contributing to the safety and development of the elevator industry.

We almost have all the process in house, including machining(cnc milling,cnc turning, grinding), sheet metal fabrication(laser cutting, stamping, deep draw, bending, tube bending, welding). So Tower can make finished products, assembly parts like elevator parts in house, which can have better price and better control on quality also.

There are different variations in the basic design of linear actuators such as ball screw actuators, worm drive actuators, acme screw actuators, tubular linear actuators, and linear slide actuators.Compact linear actuator has the most performance for these actuators
