Characteristics:- Rope drive design- Rope guide- Central lubrication- Hoist motor- Hoisting brake- Hoist gearbox- Limit switch- Controls- Overload protection- Condition monitoring- Dimensions

Product ArgumentationHoist Concept

BENEFITS

- Tilted sheaves- True vertical lift- No lateral hook drift- Large drum diameter- High-strength flexible wire ropes- Single drum configuration

- Less wear on rope and rope guide- Extended life time for rope- Optimal usage of available space- Avoids heavy twin hoists- Savings in ownership

Rope Drive DesignProduct Argumentation

BENEFITS

- Full wrap cast iron ring- Proper rope guidance- Avoids dangerous slack rope

situations- Tolerates side pulling

- Increased safety- Economical guidance of ropes on

drum- Extended rope life time- Savings in ownership

Rope GuideProduct Argumentation

BENEFITS

- Easy and fast access to lubrication points

- Lubrication process save, no point will be forgotten

- Less downtime

- Lower maintanance costs

- Safe

- Savings in ownership

Central LubricationProduct Argumentation

BENEFITS

- ONE inverter motor, no micro motors- Closed loop with Encoder- Only one size per hoist frame

o 44kW CT17o 60kW CT18o 94kW CT19 and CT20

- Temperature monitoring- Fan cooled, CT19/20 with external fan

- Very slow speed for precise handling- Fast lifting speeds for high

productivity- Less maintenance and wearing parts

(no micro motors)- Jogging and inching are avoided

Hoist MotorProduct Argumentation

BENEFITS

- Magnetic dics brake- Hoist duty lifetime rating- High brake torque, 200%- Fully enclosed, IP 66- No adjustment needed- Minor wear, holding brake!

- High safety

- Extended brake lifetime

- Less maintenance costs

- Savings in ownership

Hoisting BrakeProduct Argumentation

BENEFITS

- Oil lubricated- Grinded helical gear wheels- Only one size per hoist frame

o 1:82 CT17o 1:105 CT18o 1:128 CT19o 1:524 CT20

• Long lifetime due to high accuracy manufactuting

• Less downtime• Less maintenance cost• Less different spare parts, less

different training efforts

Gear BoxProduct Argumentation

BENEFITS

- Geared upper and lower limit switch

- Four full adjustable switching points

- Hook block operated upper limit switch

- Increased reliability and safety

- No mechanicle wearing parts

- No damages to hoist structure in case of damaged gear limit switch

Limit SwitchProduct Argumentation

BENEFITS

- Set cubicles with readily configured controls

- Space for additions (bridge inverters)- Horn 108 dB- Lightning in every panel- 230V 10A socket outside and inside- PLIOTEX wire marking- Special flat-cable entry- Cubicles 1,5m/1m/0,4m with 2 doors

- Easy and effecient integration into crane system

- Fast and easy access

- Easy maintenance

ControlsProduct Argumentation

BENEFITS

- Overload protection by strain gauge sensor

- Measures rope force at pulleys

- Cuts hoisting if force exceeds maximum pre-set limit

- Protects hoist, crane and buidling structure from overloads

- Increased safety at work

Overload ProtectionProduct Argumentation

BENEFITS

- NovaMaster as standard- Overload supervision- Brake slippage and locked brake

monitoring- Thermal motor protection - SWP counter- Tandem hoist sychronisation optional

- Enhanced safety at work- Optimized service intervals- Lower downtime and cost of owner

ship- Indentification of miss-use

Condition MonitoringProduct Argumentation

BENEFITS

- Compact track gauge- Compact wheel base- Low headroom, top of rail to top of

hoist- Equal wheel loads distribution, due to

true vertical lift- „It‘s a winch“, as opposed to a

package hoist

- Optimal usage of space- Safe operation, no side pulling at

runway end required- Lower investment in steel work- Longer lifetime, high availability- Investment savings

- Hoist tandem control, sychronization

- Crane tandem control

- Anti sway control

- Main and auxilary hoist

- Motorized hook

- Cable reel

SolutionsOverview

Look ahead!

- Standard, NovaMaster Tandem:• Electronic monitoring of safe tandem

operation of two hoist• Signal transmission between hoists

via BUS cable• Load summarization and crane

overload

- Options:• Anti collision device• LED load display, Sum load• Lifting speed synchronization via

inverter of two or more hoist motors on common crane

SolutionsHoist Tandem Control

CAN-bus

Look ahead!

- Electronic monitoring of safe tandem operation of long loads by two cranes

- Signal transmission between cranes via advanced radio controls

- Anti-collision via photo-cells and reflectors

- Matches the requirements of performance level “c” as per EN 13849

- Most comprehensive monitoring of crane conditions on tandem controls in the industry

- Highest safety standard in the industry

SolutionsCrane Tandem Control

Look ahead!

- Avoids harmful load peaks. Mechanical stress in electrical and mechanical parts is reduced (less maintenance)

- Crane is easy to operate with optimal crane movements

- Operator’s focus is in controlling the load movement and not the hoist or crane movement

- Time is not lost in increased load swing and extended time to place the loads and the load handling is more efficient
