A 4-story office building has a 3-stop dumbwaiter installed! There is an inspection hatch at the top that contains the control panel and other equipment.

Maximum load capacity of 160kg, easily ascends and descends stairs with a 35-degree slope using the cart's caterpillar tracks! The handle is adjustable, greatly improving maneuverability!

Self-locking winches, rack jacks, and reducers are widely used in various devices and fixtures. The key factors are lightweight, smart, and compact!

No need for brakes or stoppers! A self-locking winch that can operate without power and can hold loads. Lightweight, smart, and compact with many applications!

Elevate and stop the work at the desired position to hold the load! This is a disaster prevention rack jack that can be operated manually or with a commercially available electric screwdriver. It can be used even during a power outage!

Roll up the work and self-lock at the position where the handle is released! No need to unlock, can restart in both forward and reverse rotation from the stopped position! Lightweight and compact with many applications!

No need for brake stoppers! Self-locks at the stopped position during work elevation! Lighter operation than screw types, faster lifting speed! Additionally, space-saving!

No need for brake stoppers! Self-locks at the stopped position during work elevation! Lighter operability and faster lifting speed than screw types! Ideal for explosion-proof measures!
