The PITCH PF electric chain hoist incorporate latest technologies, to achieve highest performance and safety under any circumstance. Redundant overload systems offer both electronic and mechanical protection for the hoist and the supporting structure above.
Higher Durability
The PITCH PF chain hoist is build with an excellent drive system build around a sturdy and high efficiency gearbox, a high performance TENV electric motor, and an electronic speed controller. Adjustable geared limit switches for upper and lower end positions are integrated into the IP66
main control panel, together with the controller and lifetime design brake. All serviceable components, such as the patented chain guide and sprocket wheel are easily accessible.
Easiest Maintenance
A fully new designed and patented slipping clutch can withstand long time running against load without wear and tear, and is located before the brake in the load train, so the operator has full control over the load in any situation. But before the slipping clutch comes into action, overload situations while lifting a load are already detected by the electronic overload system and will switch of the speed controller and engage the spring loaded fail safe brake.
Higher Performance, better handling
The patented pairing of the Controller and the electric motor ensures optimal efficiency and full torque control over the whole speed range. The construction of the aluminum housing ensures the heat dissipation, without forced cooling applied.
Improved safety
The lifting and lowering movement is gently regulated by the inverter control. Impacts are avoided, thus protecting the hoist and suspension structure. They enjoy the full benefit of a longer service life, resulting in a beneficial reduction in operating costs.
FEATURES
Compact and robust
The robust aluminum-magnesium die-cast housing allows for optimal cooling of the engine, transmission and control unit during operation.
Service-friendly
Easy replacement of chain guide and chain drive wheel without disassembling the chain hoist and without special tools.
Suitable for outdoor use
By designing the chain hoist to protection class IP66, it is both dust-tight and protected against water jets.
Cable connectors for Control cable and main power
No electrically competent person is required to connect the hoist.
Gentle Lifting and lowering
Precise load control through frequency inverter. The control unit provides optimum monitoring of the hoist in its safety devices.
Geared Limit switches
For upper and lower hook end position easily adjustable in any position. Lifting heights up to 20 metres.
Maintenance-free brake
Positioning behind the slipping clutch for maximum safety.
