Mast unit base skid structure is constructed from high grade anodized aluminum tubing frames suitable for marine application and it has been specially designed for slickline / e-line PCE stack assembly support applications

The mast is provided with below mentioned sheaves for running wireline. Mast is designed to operate within 60 mph wind speed and the design complies DNVGL – ST - E378

5/16” wire rope sheave (22”)

Mast is fitted with

  1. One main hydraulic winch rated for 12,000 lbs
  2. One Manrider hydraulic winch rated for 3,306 lbs
  3. All winches come with internal brake and fast re-spooling system
  4. Easy deployment of sheave head
  5. One transpotaton skid is provided to carry the jibs and other tools
  6. Mast can be rigged-up within 20 to 25 minutes by two trained and certified operators
  7. External rig power supply socket
  8. Additional 20 Ft jib to operate the mast at 90 Ft height
  9. Load moment indicator with A2B block


  1. Remote operator control console
  2. Two outriggers – Manually positioning towards well side and hydraulic jacks for ground support
  3. Hazardous area rated A2B
  4. Zone-2 rated chopper lights provided on top of the boom
  5. Positive pneumatic boom locking system enables to transfer loads only to the pins instead of loading on hydraulic cylinder
  6. Counter balance valves on hydraulic cylinders and winches
  7. Bottom boom locking pin
  8. Mast is suitable to Rig-up and Rig down during the wind speed within 30 mph


Mast is hydraulically lifted upright position (90°) and extended the booms with a double acting single stage hydraulic cylinder and rope pulley mechanism. The hydraulic cylinders are equipped with dual counter balance valve for safety. The boom lifting and extension is performed by means of direction control valves designated for each cylinder.

V-Shape sheave head is equipped on top of the mast with independant pullyes for main winch and man rider winch. The sheave head is bolted connection and is suitable for 70 Ft height and 90 ft height with jib. During the rig-up time the sheave head will be folded out and turn to vertical position and lock with pin. The sheave head is foldable type and is kept folded toward the boom side in horizontal position during taxi position.

During the booms extended vertically updard a positive locking system is applied automatically in designated slots by means of pneumatic cylinders. The positive loack is working in fail safe mode as the locking is by spring action and realease of the lock only with air supply.

Main winch wire rope is 16 mm with the single sheave hook block at the lifting end. The winch is operated by means of directional control valve on the control console. A manrider winch with 10 mm wire rope with single shur lock hook on the lifting end. The man rider winch is operated from control console by means of direction control valve designated for the same.


The operator console is built with stainless steel machine engraved English letters color coded and is equipped with:

  1. Hydraulic pressure gauge 0 - 3,500 PSI
  2. Mast boom erection control valve
  3. Mast boom extension control valve
  4. Manrider winch direction control valve
  5. Control valves for Outrigger jacking
  6. Hydraulic pressure control valve
  7. Load Moment Indicator (LMI display panel)
