Type of towable boom lift:

The main types are: Diesel self-propelled type, trailer type, hand-held type, battery type, vehicle type.

Uses of towable boom lift:

Towable boom lift is widely used for installation, maintenance and climbing operations in municipal, electric power, street lamps, advertising, communication, photography, gardens, transportation, docks, airports and ports, large industrial and mining enterprises and other industries.

It is applicable to all kinds of rugged terrain in the field and has a wide range of space operation. It is mainly used for construction, bridge construction, ship manufacturing, airport, mine, port and wharf, construction of communication and power facilities and engineering machinery and equipment for outdoor advertising.

Diesel towable boom lift, without external power supply, is suitable for field high-altitude erection operation. It uses diesel power to drive walking and lifting, with large power and fast walking speed.

Trailer towable boom lift: 

It can be hung on the car and synchronized with the car. It is suitable for field high-altitude operation. 

Lifting mode: 

•  Use 380-220v power supply. 

•  It is inconvenient to use the power supply. You can use the battery to drive the lifting. Beautiful appearance and convenient walking.Vehicle mounted curved arm elevator: install the curved arm elevator on the vehicle and use the vehicle power to drive the lifting. Suitable for long-distance field high-altitude operation.

Characteristics of towable boom lift

(1) Towable boom lift has a new type of fully hydraulic self-propelled special chassis. The self-propelled aerial work lifting platform vehicle with completely independent intellectual property rights adopts the technologies of electromechanical hydraulic integration, reliability design and computer-aided design, and successfully develops a fully hydraulic driven, self-propelled special chassis, which breaks through the limitation that the previous towable boom lift can only be refitted by automobile or crane chassis.

(2) Driving with load and good operation stability. The chassis structure breaks through the traditional design theory and method, and reduces the center of gravity offset by optimizing the overall layout and load distribution of the upper platform. The unique large angle rear elevation hinge structure is adopted, and a variety of counterweight modules are reasonably set to effectively balance the working torque. The H-shaped variable cross-section composite box girder cutting frame and high load solid rubber tire are adopted to increase the overall stiffness of the chassis, ensure the stability of the whole machine during driving and operation, and realize the function of traveling with load.

(3) Multifunctional and multipurpose aerial work device. Through the boom front-end bracket, the lifting device or manned platform can be quickly installed to realize the functions of material lifting, lifting and manned high-altitude operation. At the same time, it provides an interface for expanding the operation device and rapid switching of various working devices.

(4) Towable boom lift has a unique three-dimensional rotating lifting device. The designed three-dimensional rotary lifting device can not only automatically maintain the posture of the lifted material, but also realize the adjustment requirements of the lifted material at any height, any position and any direction in the space. The speed control is accurate and sensitive, and the micro motion performance is good, which meets the requirements of high-altitude operation and ventilation pipe installation in large caverns.

Working principle of towable boom lift

The hydraulic oil forms a certain pressure by the vane pump and enters the lower end of the hydraulic cylinder through the oil filter, flameproof electromagnetic directional valve, throttle valve, hydraulic control one-way valve and balance valve to make the piston of the hydraulic cylinder move upward and lift the weight. The return oil at the upper end of the hydraulic cylinder returns to the oil tank through the flameproof electromagnetic directional valve. Its rated pressure is adjusted through the overflow valve, and the reading value of the pressure gauge is observed through the pressure gauge.

The piston of the hydraulic cylinder moves downward (i.e. the weight drops). The hydraulic oil enters the upper end of the hydraulic cylinder through the explosion-proof electromagnetic directional valve, and the return oil at the lower end of the hydraulic cylinder returns to the oil tank through the balance valve, hydraulic control check valve, throttle valve and explosion-proof electromagnetic directional valve. In order to make the heavy object drop steadily and brake safely and reliably, a balance valve is set on the oil return circuit to balance the circuit and maintain the pressure, so that the falling speed will not be changed by the heavy object. The flow is adjusted by the throttle valve to control the lifting speed. In order to ensure safe and reliable braking and prevent accidents, a hydraulic control check valve, namely hydraulic lock, is added to ensure safe self-locking in case of accidental bursting of hydraulic pipeline. Overload sound control alarm is installed to distinguish overload or equipment failure.

Disassembly steps of towable boom lift

Step#1. Remove the ring gear guard.

Step#2. Remove the reducer

Step#3. Remove in sequence

Step#4. Snap ring

Step#5. Tubing

Step#6. Hydraulic motor

Step#7. Reducer (three screws)

Step#8. Take off the gear

Step#9. Rotating mechanism

Step#10. The lower two hoses and the upper two thin tubes

Step#11. Remove the four 8# rotating head screws

Step#12. Remove the two wires (plugs)

Step#13. Lifting straight arm

Step#14. Before hoisting, tie the two arms tightly with iron wire to prevent the straight arm from stretching and moving

Step#5. The lifting points are on both sides of the main oil cylinder

What preparations are required before using towable boom lift

It is a widely used product based on the principle of hydraulic elevator and electronic integrated controller, which can timely adjust the height without manually stopping the lifting ladder, make the operation safer and more convenient, improve the operation efficiency and save the rest force. that

• Step 1: check whether the operation of the electrical equipment of the towable boom lift is normal to ensure that it can operate smoothly.

• Step 2: ensure that the pins of each connecting part are stuck, and the touch part is smooth and normal.

• Step 3: conduct the upper and lower limit action test of towable boom lift first, and use the product after it is normal.

• Step 4: check whether the steel wire rope has broken strand, burr and deformation, which conforms to the application specification of steel wire rope.

• Step 5: check whether the transmission settings of each part on the towable boom lift guide rail are jammed and whether the operation can stop smoothly.

• Step 6: the machine can be operated only after the hydraulic pump station, hydraulic cylinder and other important parts of the towable boom lift are debugged normally.

Precautions for installing towable boom lift

1. Align the 18 screws of the rotating gear

2. Pay attention to the key when installing the reducer

3. When installing the reducer head, put down the wire and two pipes, and then connect the hose
