WELLD Flat Top Tower Crane

Hoisting mechanism

The hoisting mechanism of WELLD tower cranes is crucial for vertical movement of loads. Its primary purpose is to lift and lower materials on a construction site. It comprises a motor, gearbox, drum, and wire rope, working in unison to provide the necessary power and control for precise and safe handling of heavy objects, enabling efficient construction processes.

Hoisting mechanism	Items		Unit	Parameters
	Rated single rope tension		t	2.5
	Wire rope	Specification		4Vx39S-Φ14-1960
	Reel	Ropecapacity	m	≥550
	Motor	Model		YZP2-225M2-4
		Power	kW	45
		Rotational speed	r/min	1470(50Hz)

WELLD Flat Top Tower Crane

Trolleying Mechanism

The trolleying mechanism of a tower crane is responsible for moving the hoist trolley horizontally along the jib. Its primary purpose is to position the lifting hook directly over the load to be lifted or the point where the load needs to be placed.This horizontal movement allows the crane operator to precisely control the placement of materials on a construction site, ensuring efficiency and safety during operations.

Trolleying mechanism	Items			Unit	Parameters
		Specification			6×19-Ø7.7-1770
	Wire rope	Length	65	m	Front rope	145	Rear rope
			60	m		135
			55	m		125
			50	m		115
			45	m		105
			40	m		95
			35	m		85
	Trolleying speed			m/min	0～60
	Motor		Model		YVFE132M-4
			Power	kW	5.5
			Rotational speed	r/min	1420

WELLD Flat Top Tower Crane

Slewing Mechanism

The slewing table, or slew ring, is crucial for a tower crane's operation. The primary purpose is to allow the crane's upper structure—jib, counter jib, and machinery—to rotate horizontally 360 degrees. This enables the crane to lift and place materials across a wide working radius without repositioning the entire crane.

Slewing mechanism	Items		Unit	Parameters
	Motor	Model		YTLEJ112L-120-6F1(6F2)
	Motor	Power	kW	5.5×2
	Reducer	Transmission ratio		195
	Reducer	Output moment	N.m	12000×2
	Output gear parameters	Modulus		12
		Number of teeth		16
		Modification coefficient		+0.5
	Main engine speed		r/min	0～0.6

Hydraulic Jacking Mechanism

The jacking mechanism in tower cranes facilitates self-erection. Its purpose is to progressively raise the crane's height by adding mast sections. This crucial system allows the crane to "grow" with the building it's constructing, providing the necessary lifting height for tall structures.

Jacking mechanism	Item		Unit	Parameters
	Pump station, motor	Power	kW	7.5
	Pump station, motor	Rated working pressure	MPa	35
	Jacking cylinder	Cylinder/Rod diameter	mm	φ160 / φ110
		Rated jacking force	t	70
		Jacking speed	m/min	0.6
