Four-post lift, central manual safety lock release, mobile kit, 4t

The Four-post lift STD-5640PL is a professional-grade parking and service lift designed for lifting vehicles up to 4000kg. Built with a reinforced steel structure and industrial hydraulic system, it provides stable, synchronized lifting and multi-level mechanical safety protection for workshops and service environments.

With a maximum lifting height of 2000mm, the lift offers 187cm usable clearance under the raised platform, ensuring comfortable access for underbody inspection and service operations.

Structural design and platform

• Full-length anti-slip diamond plate steel runways
• Integrated drive-on ramps
• Raised rear wheel stop plates
• Removable heavy-duty center trays
• Central sliding jack tray rail
• Reinforced closed steel runway construction
• Wide steel base plates with multiple anchoring points

The platforms measure 4475mm in length and 480mm in width, providing stable vehicle positioning.

Lifting system

The lift operates with a single hydraulic cylinder installed inside one runway, combined with a steel cable synchronization system.

Key elements:

• Heavy-duty hydraulic cylinder
• Chrome-plated piston rod
• Multi-point steel cable anchoring
• Steel equalizing cables running through columns
• Reinforced underside frame construction
• Protected hydraulic hose routing

The opposite runway does not contain a cylinder, confirming the synchronized cable-driven design.

Hydraulic power unit

Mounted on the main column, the hydraulic unit includes:

• Vertical steel oil reservoir
• Electric motor and gear pump
• Manual lowering valve lever
• Industrial hydraulic connections
• Protected cable routing

Hydraulic oil type: AW-32 or ISO-32
Oil capacity: approx.9L

Safety system

The lift integrates multiple independent safety layers:

Double mechanical safety locks

• Dual locking teeth system
• Simultaneous mechanical engagement
• Load held mechanically, not hydraulically

Central manual lock release

• Mechanical linkage to both locks
• Simultaneous release on both sides
• Independent from electrical and hydraulic systems

Cable failure safety spring

• Preloaded fail-safe spring mechanism
• Automatic lock engagement if cable tension is lost

Upper limit switch

• Installed at top of column
• Prevents over-travel
• Stops lifting at maximum height

Hydraulic safety

• Pressure relief valve (factory preset)
• Controlled manual lowering valve

Electrical control system

• Rotary main power isolator switch
• Emergency stop button
• Illuminated power indicator
• Industrial sealed control box
• Clearly labeled control instructions
• Motor power: 2.2kW
• Power supply: 230V

Mobile kit

The lift includes a mobile kit with 4 wheels.

• Integrated mechanical wheel deployment system
• Durable workshop-grade polymer wheels
• Allows repositioning of the lift within the workshop
• Designed for indoor relocation only
