Design details

Description: Compact design makes it ideal for operations in narrow aisles or spaces. This Motorized hydraulic elevator is made up of stronger and rigid manganese steel. With a motor device and a spring towing handle for pulling, pushing & steering the table, it can save man power a lot. Suitable for one single person operation, mainly used in airports, convention and exhibition center, hotel, supermarket, factory, warehouse, station, dock, station and other places for material handling or fixing or construction.

 

Technical Characteristics

Operating principle: (1) Electrically controlled hydraulic system to support lifting movement. (2) Four fixed wheels to assist travelling movements

All the parts are designed so that the forces do not exceed half the yield strength of the material used.

The elevator is fitted with overload valve and slow lowering valve to control the lowering speed. It can be fitted with many extras including roller tops, bellows, ball tops etc.

Hydraulic system

The hydraulic unit comprise a squirrel cage induction motor, a high pressure gear pump, a distributor with solenoid valves and a start up valve, Highly compensated VSC lowing valve

 

Mechanical part

The upper and lower chassis will be oversized. The upper chassis plating is smooth metal plate at least 6mm thick.

The electrical cabinet and systems as well as hydraulic gear will be mounted on the chassis.

 

Lifting arms

The plate will be elevated by actuating 2 single-action hydraulic jacks acting directly on the lifting arms guided by the roller bearings, smoothly lifting up and lowering down.

 

Electrical part

The electrical power supply is 380V, 50 Hz, three-phase, 4 wires. The supply installed beneath the basic chassis, comprise:

-The electrical cabinet,

-The power and control cables,

-The control systems,

-The operating and safety switch gear

All steel tube cable outlets will be protected by insulating ferrules.

 

Electrical cabinet

All electrical and electronic control, regulation and other equipment are placed in this cabinet whose protection index will be IP 55. Side opening drawer for convenient and easy maintenance and operation purpose. Sufficiently large louvers provide good ventilation

The cabinet comprise:

- A main, three-pole isolating switch with fuses preventing single-phase operation,

- A main contactor-circuit breaker,

- Contactors and relays used for operation of the elevator table,

- Magnetic/thermal protection of the motor pump unit,

- The transformers supplying the low controlled voltage (24V)

 

Control button box

The control button box is both at ground and platform for convenient and control. It has many commands, door to lock, protection from rain, moisture and dust.

The box comprise:

- 1 voltage presence lamp,

- ON/OFF button,

- UP and DOWN buttons,

- One emergency stop pushbutton, just acting on raising and lowering movement

 

Precaution

• Auxiliary lowing system
• Anti-burst device for cylinder
• Overload safety protection device
•  screw-type support levelling device
• Rain-proof control cabinet
• Emergency stop botton
