· Transmission and structure: It uses a disc brake motor as the power, coupled with a high-efficiency reducer, and uses a high-strength tensile shell or a die-cast aluminum shell, which is small in size, light in weight and high in strength. ·Safe braking system: Usually equipped with dual braking systems, such as electromagnetic brakes and mechanical brakes working together to ensure reliable braking. There may also be overload protection devices. · Safety protection devices: including upper and lower limit switches, reverse protection device (to prevent incorrect power connection), 24V/36V low-voltage control system (to ensure operator safety), etc. · Lubrication and maintenance: The gearbox may use an oil bath lubrication system, which can effectively lubricate the gears and cool the mechanical brakes. Its structural design also facilitates maintenance.
