Q1: What exactly is a Luffing Jib Crane, and how does the EL15/22 work?A: Unlike standard "hammerhead" cranes with a horizontal jib, a luffing jib crane like our EL15/22 can raise and lower its entire jib (arm). This "luffing" motion allows the crane to change its working radius by tilting the arm v

Q1: What is the 75QP30HS-G27 hoist mechanism used for?It is used to lift heavy materials (steel, concrete, prefab parts) on tower cranes. Q2: What is its work level?Its work level is M5, which means it is designed for frequent, heavy-duty lifting. Q3: What is the motor power and speed?Motor power is

Q1: What is the WSD-E11?A: It’s a wireless, explosion-proof wind meter (anemometer). It measures wind speed, direction, and temperature, then sends that data wirelessly to a display receiver. No cables needed. Q2: Why choose wireless over wired?A: Wired anemometers need long, expensive cables that c

Q1: What is an RCS hoist reducer, and what does it do?A: The RCS hoist reducer is a speed-reducing device installed between the motor and the drum on a tower crane. Its job is to take the high-speed rotation from the motor and reduce it to a slower, more powerful speed that can safely lift heavy loa

Q1: What is a solar warning light, and what does it do?A: It is a self-contained safety light that sits on the highest point of a tower crane (usually the jib or mast). Its main job is to make the crane visible to low-flying aircraft, especially at night, dawn, or in bad weather. It flashes a bright

Q1: What is this device? What does it do?A: Think of it as a smart bodyguard for your forklift.It is a safety system that uses special sensors to measure the weight of your load. If the forklift tries to lift something too heavy, it alerts you immediately to prevent the truck from tipping over or br

Q1: Why do I even need an anemometer for my tower crane?A: Wind makes cranes unstable. It pushes the crane and the load. Without knowing the wind speed, you risk tipping over or losing control. An anemometer helps your team know when it’s too windy to lift. Q2: What’s wrong with a traditional (cable

Q1: What does a hoist motor actually do? Why is it so important?A: Think of the hoist motor as the engine of your crane. It provides the power to:Hoist: Lift heavy loads up and down.Slew: Rotate the crane left and right.Travel: Move the trolley along the jib.Without a strong, reliable motor, you los

Q1: What exactly is a tower crane inverter? Does my crane really need one?A: Think of it as the intelligent command center for your crane.Instead of the old "abrupt start-stop" method (which jerks the load around), the inverter controls the speed and torque smoothly. It turns a rough ride into a sof
