PREFACE

Dear Customer,

Jinlong Europe, a revolutionary evolution!

Reliability, quality, safety, and high technology are the success of Yongmao’s topless tower cranes all over the world.

In Europe all our cranes are CE approved. This is the result of a constant technological research.

The absence of tie-bars allows an optimized erection (quicker and safer).

The use of small sized mobile cranes saves air space. The best solution for installation in job sites next to airports or in the city with several cranes in use and interfering working areas.

Because of our relentless efforts to improve our products, technical updates are from time to time necessary. Therefore, the technical data in this manual are subject to change without warning.

Topless tower cranes, a revolutionary evolution.

1.2.2.4. DIMENSIONAL FEATURES OF THE FOUNDATION ANCHORS

The foundation anchors are placed symmetrically in the foundation block and are to form a 1,6 m square, based on the dimensions of the mast to be erected.

The distance between the topside of the mounting plate and the topside of the foundation block must be 150 mm (see fig).

ATTENTION : Cutting or reducing the reinforcement in the foundation is prohibited.

- 28 - RCVC1.0ENG

1.2.2.5. INSTALLING THE CRANE FOUNDATION The foundation anchors are mounted by means of:

− 4 foundation anchors and 8 associated pins − 1 foundation framework and 8 associated pins − 1 standard mast section − 1 plumb line or measuring device

- Check the framework for any deformation during transport. The difference between respectively the diagonals and the bearing surface heights may be at the most 2 mm.

- Install the foundation anchor on the reinforcement and adjust by means of filling plates.

- Check perpendicularity in both directions after assembly of the lower mast section on the framework. Adjust if necessary.

- Pour the concrete block and wait until it is completely hardened before removing the mast section and the framework

2.4. HOISTING WINCH OPERATING PRINCIPLE The hosting winch is equipped with a three-speed motor coupled to a mechanical gearbox.

At start-up, the brake is released, after which a selection can be made between:

- Low hoisting speed (PV)

- Medium hoisting speed (MV)

- High hoisting speed (GV)

When the hoisting movement is interrupted, a built in (0,5 – 1 sec) electric time delay prevents undue loading of the mechanical brake, in order to avoid abnormal wear.

Normally, the medium (MV) and high (GV) hoisting speeds are used.

Low hoisting speed (PV) should only be used to pick up or position loads and thus only for short times.

CHAPTER 3. SLEWING MECHANISM


- 59 - RCVC1.0ENG

3.1. SYMBOLEN: (EX. RTC 95) R T C

3.1.1. DESCRIPTION:

Select the slewing speed suitable for the required movement. Gradually increase or decrease the slewing speed. Slow down gradually instead of stopping the load abruptly with the slew brake.

The slew brake may only be used to position the jib during hoisting at wind speeds < 13 m/s (46 km/h).

Avoid simultaneous slewing and hoisting to prevent damage to the hoist rope (rope twisting risk).

Couple (N.m) Current brake Voltage regulator Slewing mechanism


- 60 - RCVC1.0ENG

3.2. SLEWING UNIT 3.2.1. DESCRIPTION

The RTC slewing unit consists of: ( zie fig.2.2.1-1):

- A motor with squirrel-cage armature turning at constant speed in the desired direction.

- An electrodynamic coupling/brake to perform the speed changes.

- A gearwheel in which the clutch engages directly on the slewing ring.

- Safety brakes mounted on the electrodynamic coupling/brake.

- Tacho-dynamo, for speed control.

- Slewing limiter.

- The crane can be put in weathervaning both manually and electrically.


- 61 - RCVC1.0ENG

3.2.2. OPERATION

1/ Make the motor run in the desired direction.

2/ The brake releases.

3/ The electrodynamic brake inductor is supplied with direct current.

4/ An amperage change in the inductor produces a speed change. In that way, the desired speed can be obtained by means of the control box.

AT STANDSTILL:

- The power supply to the motor is switched off, power is supplied to the inductor of the electrodynamic brake and the jib is brought to a stop;

- The safety brake only locks when, in case of necessity, the operator presses the thereto-provided button.

ATTENTION: Stopping the jib by counter-slewing is prohibited.

At the end of the workday, the jib must be placed in weathervaning.

4.2. COMPOSITION OF THE TROLLEY WINCH UNIT The DTC trolley winch unit consists of the following components (see fig. 3-2-1):

- Rope drum - Gearbox - Electric squirrel-cage motor - Electromagnetic brake - Disk brake

Three speeds are available: MV: Low speed, realized by a combination of actuation of the

electromagnetic brake and running of the motor at lower voltage (230 -260 V).

PV1: Medium speed, realized by partial actuation of the

electromagnetic brake and control of the motor voltage (380 V).

PV2: High speed; the motor is run at its rated voltage (380 V)

without excitation of the electromagnetic brake. The disk brake of the trolley winch unit is of the regular closed type (i.e. release through voltage control). Normal brake clearance is 0,8 – 1,2 mm. The brake clearance is set in an identical way as for the slewing motor. The brake torque is set by a spring screw Fig. 3-2-1 item 14.

4.3. TROLLEY BRAKE 4.3.1. DESCRIPTION (fig. 4.3.1-1): The electromagnetic brake starts operating as soon as the power supply is cut. Brake clearance in the active range is automatically adjusted.

1. Operating principle

Fig. 4.3.1-1 Brakes:

When the current is cut, the electromagnetic attractive force disappears. The brake spring (2) pushes the pressure disc (6) back on the brake disc (5). This closes the brake. The brake is of the regular, closed type.

Releasing the brake:

When the excitation coils (1) is energized, the pressure disc (6) is attracted and the brake pressure spring (2) is pressed in. By this, the brake discs open up.

Brake clearance:

Normal brake clearance is 0.8 to 1.2 mm. Check the brake clearance for soiling (oil - grease).

Brake moment adjustment:

The brake moment was factory-set

Releasing the brake manually: The brake can be released manually by loosening the brake yoke (3).
