Technical Parameters

CXSM Crane Equipped with CXSM Open Winch Trolley

High Load Capacity, Wide Span and Cost-effectiveness

♦ Girder made of computer-optimised box-sections
♦ End carriage of torsionally rigid and welded box-section design

♦ Optional infinitely variable cross-travel speed help to keep low sway

The CXSM double-girder Electric Overhead Travelling cranes offer high load capacinty, wide spans with a special design in European Standard. We believe this approach could provide you with a cost-effective solution. Our CXSM crane is equipped with a high quality hoisting unit - our CXSM Open Winch Trolley - to make sure the whole crane bring to you the greater overall efficiency.

CXSM Open Winch Trolley

High Load Capacity up to 320 ton

German technology; Components Localization; Inverter Control; Running Stable

Maximum lifting capacity could be up to 320, the heavy duty grade, can work in a variety of conditions; As its price close to domestic double girder crane, it is becoming a ideal product for upgrading domestic cranes.

Performance description
Lifting capacity up to 320 tons

Structure
♦ Compact design in Trolley and hoisting mechanism
♦ The driver room is designed like space cabin to ensure excellent visibility, safety and comfort when operating the crane.

♦Trolley end carriage, support beam and hoisting machinery are in rigid connection to ensure the trolley wheels touched girder stably; the sheaves is inside the support beam for detaching, repairing and maintainance easily.

♦ Hoisting limit: 4-step rotary limit switch with slow down function and phase mismatch protection; Traversing limit:crossbar limit switch; all of limit switch are enclosed and dust-proof-designed

♦ Wire rope no need maintainance and anti-rust oil; heavy duty and high-strength; strength grade > 1870N/mm2;safety factor >5

♦ European type designed brake, no need adjustment

♦High strength hook block T grade, 360 degree rotating, with safety guard.

♦ Driving device: integrating Motor, Gear and Brake in one mechanism, grinded helical gear, quiet design, sealed, no grease leak and maintainance-free.
♦ Trolley wheels: Low carbon alloy steel or ductile cast iron
♦ Localization of component kit, reducing your cost greatly, and replacing QD crane completely.

Overload Protection

One of the core components – Electronic pressure sensor is improted from German. Accurate and reliable, effectively prevent overloading and enhance security during operation. Our overload protection device and control circuit together could stop continous overloading and make the load get down safely.

Safety Monitor
We specially develop the safety monitoring unit for our CXSM trolley. It has various functions to meet the requirements of users:

♦ Calculate lifting mechanism remaining safe working time

♦ Calculate times cumulative total linting working
♦ Calculate cumulative overload times
♦ Calculate times of accumulated lifting motor starts
♦ Overheating protection and alarm forlifting motor

♦ Overload protection and alarm
♦ Brake pad thickness alarm
♦ Display fault information and maintenance tips

Beams and Bridge End Carriage

♦ The Main Beam is made by bias-rail box girders or H-shaped steel beams, Q345-B; Vertical deflection L/800; By impeller blasting treatment to meet standard Sa2.5 grade; Automatic welding process or semi-automatic; All of welding line and joint should be check by X-ray (NDT: Non-destructive testing); The double girder crane will be equipped service platform beside bridges.

♦ End Carriage is made by rectangular steel tube or welded in box structure; then one-time bored by CNC machine; Material is Steel Q345-B; Equipped double flange wheels group, buffers and Anti-derailed protection.

♦ Main beam and End carriage connected by high-strength bolt; Easy transportation and installation;

♦ Small size, light weight
♦ Smooth running, low noise
♦ Moving fast, high reliability

Electrics
With safety standard required protecting device:

♦ Loss voltage protection
♦ Grounded protection

♦ Overload protection

♦ Short circuit protection

♦ Overheating protection

♦ Overspeed protection

♦ Overcurrent protection

♦ Limit protection

♦ Faulted phase protection

The control circuit is from the output transformer, control voltage 48V, this control voltage ensure when lifting and carts, trolley run at the same time, the power output is enough to work.

The controller box protection class IP55 with waterproof; Ambient temperature: <45 °C, humidity <90%; The main power supply is three-phase four-wire 380V (± 10%), 50Hz (± 5%).

The inverter control can ensure:

♦ Precise positioning

♦ Adjustable acceleration
♦ Smooth braking
♦ Low swaying

♦ Expanding speed range
♦ Easy to operate

Festoon for Trolley

Flat cables for hoist power supply and hoist controls; Cable trolleys; C-rails and support arms; Make sure cables and slide line no mixed together.
