CH(W)B Series Semi-gantry crane is a track travelling crane. Its proper lifting weight is 1 to 100 tons. Its span can always be customized to meet customers' needs. Its proper working temperature is -20℃ to 40℃
The CH(W)B Series semi-gantry crane is a general purpose use crane, often used in machine shop to lift goods. It has 3 controlling methods: pendant control, cabin control and remote control. Using the special gear box can make the workshop widely.

	Cranes in Tandem Crane interlocking feature includes 1. FIX radio system: 2×transmitter + 2×receiver. 2. Transmitters and receivers including external antennas. 3. Connection cable from transmitter and receiver to interlocking panel. 4. Relays and RC-circuit assembly and wiring to bridge panel. 5. Electrical engineering and drawings.
	Synchronisation Functionality 1. When lifting a load simultaneously with two hooks of the same crane, Hoisting Synchronization supervises and controls both hooks so that they run at exactly the same speed. 2. Also works with imbalanced loading between the hoists. 3. Synchronization of hoisting is always activated, when the operator selects common hoist mode. Benefits 1. Hoisting Synchronization keeps the height difference of the hooks constant during hoisting. 2. Load does not tilt during lifting and lowering. 3. Increases both safety and productivity.
	Shock Load Functionality 1. Shock load prevention ensures smooth load pick-up. 2. The hoist drive monitors the load and when a quick load change is detected (when slack chains or slings become tight) the system slows down until the load is lifted. 3. Impact due to abrupt load pick-up is minimized. Benefits Longer lifetime of 1. Crane’s steel structure 2. Mechanical components 3. Wire ropes 4. Lifting devices and slings 5. Runway structure Stability, Smooth load pick-up 1. Makes the load movements more stable and safer 2. Protects fragile loads
	Load Floating Functionality 1. Holds the load at zero speed for a predefined time after the hoist motion stops. 2. Hoist motor provides the needed torque at the zero speed, hoist brake does not close. 3. Transition from hoisting to lowering takes place faster. 4. Starting the motion again is fast and smooth as the brake is already open. 5. The floating time can be adjusted: tipically 1~2 sec. 6. Similar Floating function is available to travelling motion. Benefits Longer lifetime of 1. Crane’s steel structure 2. Wire ropes 3. Mechanical components 4. Runway structure 5. Lifting devices and slings Stability, Smooth load pick-up 1. Makes the load movements more stable and safer 2. Protects fragile loads
	Sway Control Functionality Sway Control takes the crane operator’s speed command at the control and brings the load to the required speed while minimizing sway caused by acceleration and deceleration. Benefits Increased productivity 1. Higher speeds and faster acceleration rates can be used. 2. Better positioning accuracy as the load is not swaying when travel motion is stopped. Increased safety 1. Crane operator can focused on safety of load handling while not worrying about the load swing. 2. Reduced risk of collisions due to reduced load sway. Less training needed for crane operators to reach proficient level of 1. Positioning accuracy 2. Load handling safety
	Restricted Load Functionality Load restricted area can be in trolley movement direction or in bridge movement direction or both directions. Load restriction area can be symmetrical on both sides or single side restriction. Common for both areas is that the restriction beginning from certain point until end of crane structure. This point is done with magnetic limit switch on runway or crane.
	Inching Functionality 1. Inching provides a way for accurate load positioning. 2. Available for hoist motion or for all three main motions. 3. Inching increments can be preset ranging from 2 to 100mm: -Each motion can have different Inching Increment 4. Each activation of the joystick moves the motion the preset Inching Increment. 5. Activated by On/Off selector in radio or pendant. Benefits 1. The load is easier to put into position with the predefined inching incremental control 2. Makes accurate load positioning more efficient and reduces risk of collisions
	Tandem Standard, EC Master Tandem 1. Electronic monitoring of safe tandem operation of two hoist 2. Signal transmission between hoists via BUS cable 3. Load summarization and crane overload Options 1. Anti collision device 2. LED load display, Sum load 3. Lifting speed synchronization via inverter of two or more same hoist motors on the crane
	Slack Rope Prevention Functionality 1. Slack Rope Prevention is an important safety and productivity feature when lifting devices such as lifting beams are used. 2. When the load is lowered, the hoist drive detects when load has arrived on the ground and stops lowering motion. -Lifting device weight must be min. 10% of nominal load. 3. The ropes do not get slack. Ropes do not slip out the hook block. Proper connection of hook attachments to hook is ensured. Benefits 1. Increased productivity -Optimizes load handling cycle by stopping the lowering motion when the load is landed before the ropes go slack. 2. Increased safety -Reduces risk of accidents caused by lifting devices falling over -Minimizes wire rope damages by preventing excessive slack rope coming off the rope sheaves 3. Minimizes risk of damaging load with lifting device -Example: Lowering coil tong too far can damage the landed coil
	Micro Speed Functionality 1. Microspeed makes load control more precise. 2. Available for hoist motion or for all three motions. 3. Microspeed turns large joystick movement at the controls into slow and precise load movements. 4. The maximum microspeed can be preset from 1% to 99% of full motion speed. 5. Each motion can have different maximum microspeed. 6. Activated by On/Off selector in radio or pendant. Benefits 1. Microprecisely in tight spaces, increasing safety and protecting peed helps the operator control the load. 2. Useful in heavy lifting assembly applications, where very high load positioning accuracy is needed.
	Extended Speed Range（ESR） Functionality 1. Extended Speed Range allows higher lifting and lowering speeds with partial loads. 2. With loads less than 20% of capacity, the hoist can be operated up to twice the speed at rated load. 3. Stepless ESR –The maximum allowed speed is automatically calculated based on the measured load. Benefits 1. Full power of the crane can be used all the time Heavy loads – nominal speeds Light loads – extended speeds (up to 200% of nom, speed) 2. Maximized productivity No need to oversize larger mechanical and electrical components 3. Significant time savings If majority of lifts requires loads less than 20% of rated load. Particularly beneficial with long lifting height
